Feb 07, 2015· Quora User, PhD in Chemical and Biomedical Engineering. Vitamin B12 (Cobalamin) is a complex cobalt-based organic compound that is produced naturally only by bacteria, especially those that are anaerobic (e.g., environments that lack oxygen such as large intestine). Animals, plants, or fungi don''t have the enzymes to produce B12.
Bioleaching is the extraction of a metal from sulfide ores or concentrates using materials found native to the environment; namely, water, air and microorganisms. In other words, bioleaching is the commercialization of the ability of certain bacteria and archaea, found in nature, to catalyze the oxidation of sulfide minerals.
Carbapenemase Producing Organisms (CPO) refers to bacteria in the family of Enterobacteriaceae (e.g. Eli, Klebsiella, etc) and those that do not belong to this family such as Pseudomonas, that are resistant to carbapenem antibiotics by producing an enzyme to break down the carbapenem antibiotics.
Ethanol fermentation, also called alcoholic fermentation, is a biological process which converts sugars such as glucose, fructose, and sucrose into cellular energy, producing ethanol and carbon dioxide as by-products. Because yeasts perform this conversion in the absence of oxygen, alcoholic fermentation is considered an anaerobic process. It also takes place in some species of fish where it provides energy .
Cellulase-producing bacteria were isolated from soil and identified as Pseudomonas fluorescens, Bacillus subtilIs, E. coli, and Serratia marcescens. Optimization of the fermentation medium for maximum cellulase production was carried out. The culture conditions like pH, temperature, carbon sources, and nitrogen sources were optimized. The optimum conditions found for cellulase production were ...
Bacterial Spores: Structure, Importance and examples of spore forming bacteria. It contains more layers than vegetative cells. Resistance of Bacterial spore may be mediated by dipicolinic acid, a calcium ion chelator found only in spores. When the favorable condition prevail, (i.e. availability of water, appropriate nutrients) spores germination occurs which forms vegetative cells of pathogenic bacteria.
Sep 04, 2016· Endospore is a resistant, dormant structure produced by certain bacteria. As the name suggests, it is formed inside the bacterial cell when the conditions are unfavorable for bacterial growth. Commonly known endospore forming bacteria belong to the Phylum Firmicutes.
Saprophytic bacteria such as Lacto bacilli popularly known as starters make the milk sour and produce various flavours. These bacteria are largely employed in butter industry for ripening milk and producing flavours in butter. (b) Cheese making industry: Bacteria are employed in this industry.
If the body does not produce any or enough insulin, people need to take a manufactured version of it. The major use of producing insulin is for diabetics who do not make enough or any insulin naturally. Before researchers discovered how to produce insulin, people who suffered from Type I diabetes had no .
Aug 26, 2019· Produced by certain "sulfur bacteria" in the groundwater, well, or plumbing system. Produced by sulfur bacteria or chemical reactions inside of water heaters. From pollution (this is rare). May Help Other Bacteria Grow. Sulfur bacteria produce a slime and can help other bacteria grow, such as iron bacteria.
May 19, 2015· Architecture. The team picked bacillus bacteria for its hardiness and longevity. The bacteria and its food source, calcium lactate, are packed into tiny capsules that dissolve when water enters the concrete cracks. Once released, the bacteria consume the calcium lactate, causing a chemical reaction that creates limestone, which then fills in the gaps.
– Inject the produced water into the same formation or another suitable formation; involves transportation of produced water from the producing to the injection site. Treatment of the injectate to reduce fouling and scaling agents and bacteria might be necessary. While waste water is generated in this option, the waste is emplaced back underground.
MIT spinout Manus Biosynthesis engineers microbes to produce rare and expensive ingredients for noncaloric beverages, perfumes, toothpastes, detergents, pesticides, and therapeutics. Spun out of the MIT Department of Chemical Engineering, Manus technologies could lead to new discoveries in drug development and product ingredients.
population of marine fish revealed their ability to produce high amounts of histamine at low temperatures [5,9,6,10]. The tropical climate of India with an average temperature ranging between 25-40˚C is suitable for proliferation of histamine forming bacteria in fish and fish products. Various stages of fish
Apr 21, 2015· The team found that in the germ-free mice, their EC cells produced around 60% less serotonin than the mice with normal gut bacteria. And when they restored bacteria colonies in the gut of the germ-free mice, their EC cells began producing normal levels of serotonin - showing the effect on the EC cells can be reversed.
Limestone—A Crucial and Versatile Industrial Mineral Commodity. other sea-dwelling creatures use these two chemicals to make protective shells by combining them to form calcite or "aragonite," which is the same chemical composition as calcite but has a different crystal form. Some limestones have been changed . by the introduction of ...
Apr 24, 2017· Bacteria are extremely diverse, and some forms of bacteria don''t replicate through binary fission. The cyanobacteria Stanieria replicates within the cell wall, producing dozens or even hundreds of offspring called baeocytes. The cell wall ruptures, and all the baeocytes are released simultaneously.
The Pros & Cons of the Use of GMO Insulin. GMO insulin is also known as synthetic insulin, or human insulin. It is produced with genetically modified bacteria, instead of the traditional method that produces what is known as pork insulin. In this method, sometimes called natural insulin, the pancreas of a cow or pig is used to produce insulin.
It is developed in a narrow strip just above the tide line on ancient limestone rocks. If you break off a piece, you will see that the black color is present near the surface and it grades to gray inside. Second, origin – it is being dissolved largely by algae, bacteria and fungi so it is often called "biokarst".
Isolate Arba Minch Waste Water (AWW) identified as Bacillus spp was found to be the best producer. The optimum pH, temperature, and incubation period for best PHB production by the isolate were 7, 37 °C, and 48 h respectively at 150 rpm. PHB production was best .
Mar 25, 2018· Studies show gut bacteria are able to synthesize quite significant amounts of several amino acids: leucine, lysine, threonine. There is research that suggests beneficial gastrointestinal microbiota helps produce up to 20% circulating threonine and lysine, in adults and up to 20% of total dietary leucine in adult men.
biochemical limestone Limestones are rich in calcium carbonate. In a biochemical limestone the calcium carbonate is locked into the fossil shells and skeletons of marine organisms. (In a chemical limestone, the calcium carbonate is in the form of calcite mineral crystals.) As marine plants and animals die in the ocean, scavengers, waves or currents may break them apart, resulting in biochemical sediment .
Jan 11, 2019· Bacteria that produce electricity do so by generating electrons within their cells, then transferring those electrons across their cell membranes via tiny channels formed by surface proteins, in a process known as extracellular electron transfer, or EET.
Yogurt is a fermented milk product that contains the characteristic bacterial cultures Lactobacillus bulgaricus and Streptococcus thermophilus. All yogurt must contain at least 8.25% solids not fat. Full fat yogurt must contain not less than 3.25% milk fat, lowfat yogurt not more than 2% milk fat, and nonfat yogurt less than 0.5% milk.
Limestone is a sedimentary rock, made up mostly of the mineral calcite, a form of calcium carbonate, CaCO3. The calcium carbonate is originally produced by living organisms. Later, some of it goes into solution in sea water. Limestone rocks include mainly organic remains and precipitated carbonate. Limestone makes up about 10% of the total volume of all sedimentary rocks.
