一般描述
A water-soluble extract of autolyzed yeast cells, yeast extract is a mixture of amino acids, peptides, and water-soluble vitamins, for example, intact vitamin B12 complex and carbohydrates, and can be used as an additive for culture media and fermentation media. It can also be used in the resuscitation of a large variety of fastidious microorganisms.
应用
Yeast extract is recommended for use in culture media and the cultivation of various microorganisms. It provides multi-functional nutrient supplements that can also be used in microbial fermentation.

Recent attention has been given to the relationships between diet, longevity, aging and resistance to various forms of stress. Flies do not simply ingest calories. They sense different concentrations of carbohydrate and protein macronutrients and they modify their feeding behavior

Due to their cytotoxic activities, many anticancer drugs cause extensive damage to the intestinal mucosa and have antibiotic activities. Here, we show that cisplatin induces significant changes in the repertoire of intestinal commensal bacteria that exacerbate mucosal damage. Restoration of

Sugar refinery washing water (SRWW) contains abundant levels of carbon sources and lower levels of contaminants than other types of wastewater, which makes it ideal for heterotrophic cultivation of microalgae. Here, carbon sources in SRWW were utilized for conversion into

Ameliorating methane (CH4) emissions from ruminants would have environmental benefits, but it is necessary to redirect metabolic hydrogen ([H]) toward useful sinks to also benefit animal productivity. We hypothesized that inhibiting rumen methanogenesis would increase de novo synthesis of microbial
