A protein-free chemically defined medium for the cultivation of various micro-organisms with food safety significance was written by Wang, D.;Greenwood, P.;Klein, M. S.. And the article was included in Journal of Applied Microbiology in 2021.Application of 137-08-6 This article mentions the following:
To develop a broadly applicable medium free of proteins with well-defined and reproducible chem. composition for the cultivation of various micro-organisms with food safety significance. The defined medium was designed as a buffered minimal salt medium supplemented with amino acids, vitamins, trace metals and other nutrients. Various strains commonly used for food safety research were selected to test the new defined medium. We investigated single growth factors needed by different strains and the growth performance of each strain cultivated in the defined medium. Results showed that the tested strains initially grew slower in the defined medium compared to tryptic soy broth, but after an overnight incubation cultures from the defined medium reached adequately high cell densities. The newly designed defined medium can be widely applied in food safety studies that require media with well-defined chem. constituents. Significance and Impact of the Study : Defined media are important in studies of microbial metabolites and physiol. properties. A defined medium capable of cultivating different strains simultaneously is needed in the food safety area. The new defined medium has broader applications in comparing different strains directly and provides more reproducible results. In the experiment, the researchers used many compounds, for example, Calcium (R)-3-(2,4-dihydroxy-3,3-dimethylbutanamido)propanoate (cas: 137-08-6Application of 137-08-6).
Calcium (R)-3-(2,4-dihydroxy-3,3-dimethylbutanamido)propanoate (cas: 137-08-6) belongs to alcohols. Similar to water, an alcohol can be pictured as having an sp3 hybridized tetrahedral oxygen atom with nonbonding pairs of electrons occupying two of the four sp3 hybrid orbitals. Tertiary alcohols cannot be oxidized at all without breaking carbon-carbon bonds, whereas primary alcohols can be oxidized to aldehydes or further oxidized to carboxylic acids.Application of 137-08-6
