一般描述

酵母提取物粉末由选定的酿酒酵母菌株制成。推荐用于微生物培养基、发酵和其它生物学研究。酵母提取物是在受控条件下生产，从而保留其维生素含量和其它营养价值，如肽、游离氨基酸、核酸、矿物质、痕量元素和磷化合物。它富含维生素，尤其是那些B 族复合维生素，通常用于在培养基中以 0.3 - 0.5% 的浓度提供这些因子。

应用

酵母提取物尤其可用于培养基中用于培养牛奶或其它乳制品中存在的微生物，还用于检测和富集病原体和指示生物的培养基。

Biosynthesis of Nutraceutical Fatty Acids by the Oleaginous Marine Microalgae Phaeodactylum tricornutum Utilizing Hydrolysates from Organosolv-Pretreated Birch and Spruce Biomass.

Alok Patel et al.

Marine drugs, 17(2) (2019-02-20)

Polyunsaturated fatty acids (PUFAs) are essential for human function, however they have to be provided through the diet. As their production from fish oil is environmentally unsustainable, there is demand for new sources of PUFAs. The aim of the present

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

Absolute Quantification of the Central Carbon Metabolome in Eight Commonly Applied Prokaryotic and Eukaryotic Model Systems.

Lisa M Røst et al.

Metabolites, 10(2) (2020-02-26)

Absolute quantification of intracellular metabolite pools is a prerequisite for modeling and in-depth biological interpretation of metabolomics data. It is the final step of an elaborate metabolomics workflow, with challenges associated with all steps-from sampling to quantifying the physicochemically diverse
