The Gastrins: Their Production and Biological Activities
Annual Review of Physiology, 2001▪ Abstract  Gastric epithelial organization and function are controlled and maintained by a variety of endocrine and paracrine mediators. Peptides encoded by the gastrin gene are an important part of this system because targeted deletion of the gene, or of the gastrin-CCKB receptor gene, leads to decreased numbers of parietal cells and decreased ...

Biological production of 2,3-butanediol
Applied Microbiology and Biotechnology, 20012,3-Butanediol (2,3-BDL), which is very important for a variety of chemical feedstocks and liquid fuels, can be derived from the bioconversion of natural resources. One of its well known applications is the formation of methyl ethyl ketone, by dehydration, which can be used as a liquid fuel additive. This article briefly reviews the basic properties of

Biological production of 5-methylthioribose
Canadian Journal of Microbiology, 1973Production of methylthioribose by Escherichia coli was investigated under various growth conditions using sulfate as the exogenous source of sulfur. Methylthioribose was shown by tracer and chromatographic methods to be a normal biosynthetic product secreted into the medium and accumulated there.

Hydrogenases for biological hydrogen production
Bioresource Technology, 2011Biological H2 production offers distinctive advantages for environmental protection over existing physico-chemical methods. This study focuses specifically on hydrogenases, a class of enzymes that serves to effectively catalyze H2 formation from protons or oxidation to protons.

What Are Biologics, Biological Products and Biological Drugs?
2014Following the deaths of 14 children from contaminated antitoxins and smallpox vaccines, Congress in 1902 passed the Biologics Control Act, which is also known as The Virus-Toxin Law. This act required manufacturers to be licensed for safety and was a precursor and model for the Food Drugs and Cosmetics Act of 1938 which also emphasized safety.

Electricity-mediated biological hydrogen production
Current Opinion in Microbiology, 2010Anaerobic bacteria have the ability to produce electricity from the oxidation of organic substrates. They also may use electricity to support chemical reactions that are energetically unfavorable. In the fermentation of sugars, hydrogen can be formed as one of the main products.

Osmoregulation and Biological Energy Production
1980The interests of the Department of Energy (DOE) in osmoregulation research are fairly straightforward. As you are all aware, there is much being made these days about the importance of biomass and how biomass can serve as an alternate to fossil fuels. Many of these claims are highly optimistic while others tend to minimize the contribution that biomass

Biological Processes for Hydrogen Production
2016Methane is produced usually from organic waste in a straightforward anaerobic digestion process. However, hydrogen production is technically more challenging as more stages are needed to convert all biomass to hydrogen because of thermodynamic constraints.

The Biological Productivity of Waters
Journal of the Fisheries Research Board of Canada, 1966[The concept of biological production is best approached from the point of view of a product, defined as a group of organisms (not necessarily all belonging to the same species) which have similar food habits, and which are useful to man or are of special interest for some other reason.
