The Fermentation and Microbiology (FMB) department of Shell Research Centre in Sittingbourne was a leader in the development of single cell protein (SCP) production from methane and methanol in the 1970's. This updated presentation lists virtually all of the publications from the Shell scientists engaged at that time in the development of a single cell protein production process using methane and methanol as the carbon feedstocks. Their main focus was growing Methylococcus capsulatus in continuous culture on methane.
Ethanol can be produced through anaerobic fermentation of sugars and starches from various raw materials by yeast and bacteria. Saccharine materials like fruits, molasses, sugar beet and sugar cane directly provide fermentable sugars. Starchy materials like grains and tubers must be processed to break down starch into sugars through steps like milling, cooking, and conversion. The sugars are then fermented by organisms like Saccharomyces yeast to produce ethanol. The ethanol is recovered through distillation which separates ethanol (boiling point 78.5°C) from water (boiling point 100°C). Ethanol finds uses as a solvent, fuel, and chemical intermediate. Byproducts are also generated including
Positive selection allows for the isolation of mutants that are resistant to antibiotics by growing cultures on media containing the antibiotic. Only resistant mutant colonies will grow. Negative selection identifies mutants that have lost an ability, such as the ability to synthesize an essential nutrient. The replica-plating technique transfers bacterial colonies from a histidine-enriched master plate to plates with and without histidine. Mutants unable to synthesize histidine will only grow on the plate containing histidine. The Ames test uses a histidine-auxotrophic Salmonella strain to determine if a chemical is mutagenic by seeing if it causes more colonies to grow on a minimal plate lacking histidine.
The document discusses using enzymes in organic solvents rather than aqueous media. This can enhance the utility of enzymes by allowing them to catalyze reactions not possible in water, increase stability, and alter selectivity. Several approaches are described for solubilizing enzymes in organic solvents, including modifying the enzyme with polyethylene glycol chains or using reversed micelle systems. The effects on enzyme activity, stability, and kinetics are discussed for different solvent types and systems.
Glycerol can be produced by using different processes and feedstocks. For example, it can be obtained by propylene synthesis via several pathways [8], by hydrolysis of oil or by transesterification of fatty acids/oils.
This document discusses raw materials used in fermentation processes. It covers various carbon sources like molasses, fruit juices, cheese whey, starches from cereals and tubers. It also discusses cellulosic materials like sulfite waste liquor, wood hydrolysates, and rice straw. Vegetable oils and hydrocarbons can also serve as carbon sources. Ideal fermentation media should satisfy the nutritional needs of microorganisms, support high product yields, use cheap and available raw materials, and not interfere with downstream processing. The type of raw material used depends on factors like cost, availability, and product being fermented.
In this presentation I'm explaining about the production and processing of Ethanol from agricultural wastes and usage of ethanol as a fuel for engines. Also explained about the advantages and disadvantages of ethanol process and an detailed explanation about ethanol process.

Oxygen transfer is an important factor in aerobic fermentation processes. Dissolved oxygen must be maintained above the critical level for the microorganism being used, typically through aeration and agitation of the fermentation broth. The specific oxygen uptake rate of microorganisms increases with increasing dissolved oxygen concentration up to the critical level, above which no further increases in oxygen uptake occur. Maintaining dissolved oxygen concentrations greater than the critical level maximizes biomass production by meeting the microorganism's maximum oxygen demand.

Strategies to enhance production of secondary metabolitesPrashant Singam
1. Strategies to enhance production of secondary metabolites in plant cell cultures include selecting high-productivity cell lines, using elicitors to boost productivity over short periods, and immobilizing cells to improve yields of extracellular metabolites.
2. Elicitors are compounds that induce plant cells to produce more secondary metabolites in response to stress and include fungal or bacterial extracts, polysaccharides, and physical/chemical agents like UV radiation or heavy metals.
3. Immobilizing plant cells by entrapping them in matrices like alginate or polyacrylamide anchors the cells while allowing continuous production and release of metabolites into the medium.
Enzyme immobilization involves attaching enzymes to an inert, insoluble material which provides benefits like increased pH and temperature resistance. It allows the enzyme to be reused through multiple reactions by easily separating it from reaction products. There are physical and chemical methods for immobilization like entrapment within a polymer lattice or covalent attachment to a matrix. Immobilized enzymes have properties like higher stability and altered selectivity compared to free enzymes. Creative Enzymes Inc. offers custom enzyme immobilization services at any scale with high enzyme loading and variable particle sizes.
This document summarizes different types of bioreactors:
1) Stirred tank reactors use mechanical agitation for mixing and are common for enzyme and cell reactions but can damage cells.
2) Bubble column reactors use gas sparging for mixing and have simple design, good heat and mass transfer but low oxygen transfer.
3) Airlift reactors are similar to bubble columns but contain a draft tube to improve circulation and oxygen transfer.
4) Packed-bed reactors use immobilized biocatalysts and have continuous liquid flow but can suffer from blockages and poor oxygen transfer.
5) Trickle-bed reactors use downward liquid and gas flow over packed catalyst particles and are used for gas-

Promoters are regions of DNA that initiate gene transcription. They are located upstream of genes and can range from 100-1000 base pairs long. Promoters contain an RNA polymerase binding site and initiation site to control transcription. There are several types of promoters including constitutive, inducible, tissue-specific, and synthetic promoters. Constitutive promoters induce expression in all tissues, while inducible promoters respond to environmental or chemical factors and tissue-specific promoters function in particular tissues.

Unit 3.0 introduction and history of plant tissue cultureDr. Mafatlal Kher
Plant tissue culture is the process of growing plant cells, tissues or organs in an artificial nutrient medium under sterile conditions. The document discusses the history and development of plant tissue culture techniques. It notes that plant tissue culture is founded on cell theory proposed by Schleiden and Schwann in 1838-1839. Gottlieb Haberlandt is considered the father of plant tissue culture for his pioneering experiments in 1902, though his experiments failed due to inappropriate plant material and nutrient medium. Improved nutrient solutions like Knop's solution, White's medium and Murashige and Skoog medium enabled indefinite growth and multiplication of plant tissues in culture.
A variety of fuels can be made from biomassi resources including the liquid fuels ethanol, methanol, biodiesel, Fischer-Tropsch diesel, and gaseous fuels such as hydrogen and methane. Biofuels research and development is composed of three main areas: producing the fuels, applications and uses of the fuels, and distribution infrastructure.
Biofuels are primarily used to fuel vehicles, but can also fuel engines or fuel cells for electricity generation. For information about the use of biofuels in vehicles, see the Alternative Fuel Vehicle page under Vehicles. See the Vehicles page for information about the biofuels distribution infrastructure. See the Hydrogen and Fuel Cells page for more information about hydrogen as a fuel.
Biotechnology is the use of living organisms to develop useful products. It has been practiced for thousands of years in activities like brewing and baking but the term was coined in 1917. Modern biotechnology applies scientific techniques like genetic engineering to precisely manipulate biological processes. Key developments include the discovery of DNA's structure in 1953 and the first recombinant DNA experiments in 1973, allowing transfer of genes between organisms. Biotechnology now has important applications in medicine, agriculture, and industry.

SPE 199286 - Profiling the Production Performance of Five HPHT Gas Condensate...John Downs
1. The document discusses production performance from five high-pressure, high-temperature gas condensate wells in the Kvitebjorn Field in the Norwegian North Sea that were drilled and completed using cesium formate drilling fluids.
2. Logging data obtained using cesium formate brine showed improved reservoir quality, leading to a 33% increase in estimated hydrocarbon reserves. Actual cumulative production from the field has matched or exceeded revised reserve estimates.
3. Cumulative production from the initial five wells after 14 years is now higher than the original reserves projection for the entire field, demonstrating the benefits of using cesium formate fluids for drilling and completion.
SPE 145562 - Life Without Barite: Ten Years of Drilling Deep HPHT Gas Wells ...John Downs
The tradition of using barite to increase the weight of drilling fluids dates back to the early-1920’s and, while it has been of great benefit to the oil industry over the past 90 years, it has also caused some chronic and persistent well construction problems along the way. These problems, which are very familiar to drillers, include well control difficulties, stuck pipe incidents and formation damage.
The oil industry has known since the 1970’s that replacing barite with suitable non-damaging solutes in reservoir drill-in fluids is an effective way of reducing formation damage, simplifying operations and eliminating the need for expensive formation damage by-pass operations. The development of brine-based drill-in fluids opened up the opportunity to connect more effectively with hydrocarbon reserves by allowing the construction of long high-angle reservoir sections completed in open hole. Despite the advantages on offer, the industry was unable to exploit this novel technology in deep HPHT gas field developments until the mid- to late-1990’s when drill-in fluids based on potassium and cesium formate brine became available in commercial volumes.
Cesium formate brine was first used as a reservoir drilling fluid in the Huldra gas/condensate field in the North Sea in January 2001, and has now been used to drill a total of 29 deep HPHT gas wells. The information presented and reviewed in this paper confirms that the use of potassium and cesium formates as the sole weighting agents in reservoir drill-in fluids has enabled operators to enjoy the full economic benefits of creating low-skin open-hole completions in deep high-angle HPHT gas wells. The review also concludes that the use of these heavy formate brines as drill-in fluids over the past 10 years has facilitated the safe and efficient development of deep HPHT gas reserves by:
• Virtually eliminating well control and stuck pipe incidents
• Enabling the drilling of long high-angle HPHT wells with narrow drilling windows
• Typically reducing offshore HPHT well completion times by 30 days or more
• Improving the definition and visualization of the reservoirs
• Eliminating the need for clean-ups, stimulation treatments or any other form of post-drilling well intervention to remove formation damage caused by the drilling fluid
This has all been made possible by the operators’ acceptance and adoption of the award-winning Chemical Leasing (ChL) and fluid management programmes that form the basis of their contracts with the sole producer of cesium formate brine. The use of the ChL model has played an important role in reducing the unnecessary consumption of what is a very rare and valuable chemical resource
SPE 165151 - The Long-term Production Performance of Deep HPHT Gas Condensat...John Downs
Formate brines have been in use since 1995 as non-damaging drill-in and completion fluids for deep HPHT gas condensate field developments. The number of HPHT fields developed using formate brines now totals more than 40, and includes some of the deepest, hottest and highly-pressured reservoirs in the North Sea. The well completions have been both open-hole and cased-hole.
An expectation from using formate brines as reservoir drill-in and completion fluids is that they will cause minimal damage to the reservoir and help wells to deliver their full productive potential over the life-time of the field. The validity of this expectation has been tested by examining the long-term hydrocarbon production profiles of eight HPHT gas condensate fields in the North Sea where only formate brines have been used as the well completion fluids. In five of these fields the wells were drilled with oil-based muds and completed by perforating in cased hole with high-density formate brines. In another two of the fields the wells were drilled with formate brines and completed with screens entirely in open hole using the same brines. The last of the eight fields was drilled with formate brine and the wells were then completed with same fluid in either open hole or cased hole.
The results of the production analysis provide a unique insight into the impact of a single type of specialist drill-in and completion fluid on the rate of recovery of hydrocarbon reserves from deeply-buried reservoirs in the North Sea
A Ramble through Cornwall - Day 8 - Bodmin to St Neot John Downs
A short (7 mile) walk from the outskirts of Bodmin east to St Neot, skirting the southern border of Bodmin Moor. Mostly walking in fog on this particular day
This document summarizes the key findings of a study on the effects of different well construction fluids on rig time savings. The study analyzed 89 North Sea wells and found that switching from oil-based muds to cesium or potassium formate fluids can save up to 26 days of rig time. Specifically, using formate fluids for open-hole standalone sand screen completions can save over 3.5 weeks compared to cased and perforated completions using oil-based muds. Formate fluids also significantly reduce completion times for both well construction techniques and increase drilling rates of penetration compared to oil-based muds.
DMK chose potassium formate brines over invert oil-based muds for drilling long horizontal wells in the abrasive Montney shales. They experienced significant cost and time savings from increased drilling rates of penetration (ROP), longer bit life, improved wellbore cleaning, and lower equivalent circulating densities (ECDs). Operators saw ROP improvements of 30-50% and bit runs twice as long as with oil-based muds. Using solids-free potassium formate brine allowed excellent horizontal wellbore cleaning without cuttings beds forming and reduced circulating pressures.

‘‘Figma AI’’ is one of the sophisticated Artificial Intelligence based digital design and prototyping tools which has transformed the way of designers shape and share the user interfaces and experience. In essence, Figma AI is a set of advanced AI technologies aimed at improving design operations’ productivity, innovation, and accuracy. Here’s a detailed exploration of what Figma AI offers:Here’s a detailed exploration of what Figma AI offers:
**Intelligent Design Assistance:**
Another form of AI used in Figma is Real-Time Collaboration and Suggestions that go further by providing the designers with improvements as they design. It utilizes design, layout, and user flow analysis algorithms that involve machine learning to give well-structured recommendations based on the site’s design and layout as well as other designs in the current market. Moreover, this capability not only brings advantages in the aspect of time; it also benefits from the viewpoints of homogeneity and practicability across the projects.
**Automated Prototyping:**
It is also noteworthy that Figma AI can autonomously work on creating prototypes. Designers can provide the core functionalities and limitations of a system and the AI engine forms hypotheses of the prototypes which can be animated and include features like buttons and sliders. This minimize hours of work, and enable designers to work on polishing interaction and user experience aspects rather than having to create prototypes from the ground.
**Adaptive Design Systems:**
Figma AI helps in using the design systems that automatically adapt to various optimal graphic sizes and contexts of the devices. From the users’ statistics and reviews, it can propose slight modifications of the design elements that work best on different devices. This makes the deliveries user-friendly for all consumers irrespective of how they come across the product.
**Natural Language Interface:**
Another great special inclusion in Figma AI is the incorporation of NLI, which incorporates natural language to come with designers in a plain language. Designers can state or explain what they want to design, ask about some principles in the design or even more ask to create a certain asset in design, while Figma AI answers with a related design suggestion or completes a given task.
**Collaborative Design Insights:**
Being an AI tool meant to help the design teams coordinate, Figma AI provides an insight into collaborative design choices and users’ feedback. It detects areas of possible design discrepancies, proposes changes based on amass data, and facilitates the quick redesign at the same time avoiding inefficiency of the design.
**Ethical Design Considerations:**
Acknowledging the hereby discussed problem of ethical design practices, Figma AI employs algorithms that bring attention to certain biases or accessorial concerns emerging from design decisions.

Shell’s pioneering research into the growth of
continuous cultures of Methyloccus capsulatus on
methane paved the way for three independent
commercial SCP ventures in more recent times:
• Statoil Norferm – product tradename “Bioprotein”
• UniBio – product tradename “UniProtein “
• Calysta – product tradename “Feedkind “
All three ventures run continuous cultures of Methylococcus
capsulatus on methane to produce SCP – as pioneered at a
pilot scale by Shell in 1970’s
