General description

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.

Application

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.

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

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

Quorum sensing (QS) enables bacterial multicellularity and selective advantage for communicating populations. While genetic "switching" phenomena are a common feature, their mechanistic underpinnings have remained elusive. The interplay between circuit components and their regulation are intertwined and embedded. Observable phenotypes

The mechanisms that regulate cytoskeletal remodeling during the transition between mitosis and interphase are poorly understood. In fission yeast the MOR pathway promotes actin polarization to cell tips in interphase, whereas the SIN signaling pathway drives actomyosin ring assembly and
