Description

General description

Yeast extract is produced by various yeast species mainly by Saccharomyces cerevisiae or baker’s yeast. In addition to its use as a supplement in culture media for microbial research and biotechnology, yeast extract is also used as a component of the complex media for industrial fermentations.It also serves as a nutritional source for various microbial media.

Application

For general bacteriological use with a variety of microorganisms.

Yeast Extract has been used as a component of:

complex media for culturing E. coli clones for shake flask experiments
culture media for culturing bacterial species Gluconacetobacter xylinus
yeast extract beef (YEB) media for the transformation of Agrobacterium

Yeast extract is used as a bacteriological media component for a variety of microorganisms and molecular genetics applications.

Other Notes

Water soluble portion of autolyzed yeast with intact B-complex vitamins. Yeast extract is a mixture of amino acids, peptides, water soluble vitamins and carbohydrates and can be used as additive for culture media.

Caenorhabditis elegans as a model to screen plant extracts and compounds as natural anthelmintics for veterinary use.

Luciana M Katiki et al.

Veterinary parasitology, 182(2-4), 264-268 (2011-06-18)

The most challenging obstacles to testing products for their anthelmintic activity are: (1) establishing a suitable nematode in vitro assay that can evaluate potential product use against a parasitic nematode of interest and (2) preparation of extracts that can be

A comparison of the use of different swab materials for optimal diagnosis of amoebic gill disease (AGD) in Atlantic salmon (Salmo salar L.).

Carolina Fernandez-Senac et al.

Journal of fish diseases, 43(11), 1463-1472 (2020-09-04)

Routine gill swabbing is a non-destructive sampling method used for the downstream qPCR detection and quantitation of the pathogen Neoparamoeba perurans, a causative agent of amoebic gill disease (AGD). Three commercially available swabs were compared aiming their application for timelier

Origin and incidence of 2-methoxy-3,5-dimethylpyrazine, a compound with a "fungal" and "corky" aroma found in cork stoppers and oak chips in contact with wines.

Pascal Chatonnet et al.

Journal of agricultural and food chemistry, 58(23), 12481-12490 (2010-11-10)

This study identifies a previously isolated bacterium as Rhizobium excellensis, a new species of proteobacteria able to form a large quantity of 2-methoxy-3,5-dimethylpyrazine (MDMP). R. excellensis actively synthesizes MDMP from L-alanine and L-leucine and, to a lesser extent, from L-phenylalanine
