In genetics, a strain is said to be auxotrophic if it carries a mutation that renders it unable to synthesize an essential compound. For example, a yeast mutant with an inactivated uracil synthesis pathway gene is a uracil auxotroph (e.g., if the yeast Orotidine 5'-phosphate decarboxylase gene is inactivated, the resultant strain is a uracil ...
Nutritional yeast (also known as nooch [4]) is a deactivated (i.e. dead) yeast, often a strain of Saccharomyces cerevisiae, that is sold commercially as a food product. It is sold in the form of yellow flakes, granules, or powder, and may be found in the bulk aisle of natural food stores .
FCD are important in many fields including clinical practice, research, nutrition policy, public health and education, and the food manufacturing industry and is used in a variety of ways including: national programmes for the assessment of diet and nutritional status at a population level (e.g. epidemiological researchers assessing diets at a ...
Microbial food cultures are live bacteria, yeasts or moulds used in food production. Microbial food cultures carry out the fermentation process in foodstuffs. Used by humans since the Neolithic period (around 10 000 years BC) [1] fermentation helps to preserve perishable foods and to improve their nutritional and organoleptic qualities (in this case, taste, sight, smell, touch).
Recently many state and local menu-labeling laws have been passed requiring restaurants to post nutrition information on menus and menu boards, or have it readily available upon customer request. [4] Restaurants have had to perform nutrition analysis in order to generate nutrition information and conform to these laws.
The biochemical data includes 1104 protein (and DNA) sequences and more than 900 biochemical reactions (Fig. 1) that are linked to these metabolite entries. [1] Each metabolite entry in the YMDB contains more than 80 data fields with 2/3 of the information being devoted to chemical data and the other 1/3 devoted to enzymatic or biochemical data.

Since URA3 allows for both positive and negative selection, it has been developed as a genetic marker for DNA transformations and other genetic techniques in bacteria and many fungal species. It is one of the most important genetic markers in yeast genetic modification. While URA3 is a powerful selectable marker, it has a high background.
