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 ...
Next to the above-mentioned selection makers a few auxotrophic strains were generated to work with auxotrophic makers. The URA3 marker (URA3 blaster method) is an often-used strategy in uridine auxotrophic strains; however, studies have shown that differences in URA3 position in the genome can be involved in the pathogeny of C. albicans.

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 .
A calculator uses nutritional information such as total sugar, sodium, energy and other variants to obtain a rating for the product. Points are added for "healthy" nutrients such as fibres, proteins and vegetable matter whilst points are deducted for "unhealthy" nutrients that have been scientifically linked to chronic health disease, such as ...
Nutritional yeast in particular is naturally low in fat and sodium and a source of protein and vitamins as well as other minerals and cofactors required for growth. Many brands of nutritional yeast and yeast extract spreads, though not all, are fortified with vitamin B 12, which is produced separately by bacteria. [96]
Nutritional yeast is a type of yeast (like baker’s yeast or brewer’s yeast) that’s grown specifically to be used as a food product. The yeast cells are killed during manufacturing and not ...
Another method of selection is the use of certain auxotrophic markers that can compensate for an inability to metabolise certain amino acids, nucleotides, or sugars. This method requires the use of suitably mutated strains that are deficient in the synthesis or utility of a particular biomolecule, and the transformed cells are cultured in a ...
A study recently published in Nutrients explored the nutritional value of certain processed foods with protein claims. Recently, the general public has increased its consumption of food products ...
