General description

Yeast extract is an extract of autolyzed yeast cells. Yeast extract is a mixture of amino acids, peptides, water soluble vitamins and carbohydrates and can be used as additive for culture media. It is a non-animal and low endotoxin peptone suitable for use in fermentations media for cultivation and resuscitation of a large variety of fastidious microorganisms. It is rich in vitamins and other nutritive substances and so, recommended for general laboratory media

Application

Yeast extract is recommended for use in culture media and for the mass cultivation of various microorganisms. It provides multi-functional nutrient supplements that can also be used in microbial fermentation.

LsrR quorum sensing "switch" is revealed by a bottom-up approach.

Sara Hooshangi et al.

PLoS computational biology, 7(9), e1002172-e1002172 (2011-10-08)

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 mitosis-to-interphase transition is coordinated by cross talk between the SIN and MOR pathways in Schizosaccharomyces pombe.

Samriddha Ray et al.

The Journal of cell biology, 190(5), 793-805 (2010-09-02)

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
