Metabolism microbial

In section 9.3, we discussed in general terms the use of microbial metabolism to selectively remove the side chain from sterols to produce steroids. This removal may also be accompanied by some modification to the ring structure. We did not, however, discuss in any detail any specific reactions. In this section we will focus on some specific reactions. 

In the soil, an imbalance of amino acids, the presence of D-amino acids derived from microbial metabolism, or analogs and homologs of constituent protein amino acids could produce a deviation in the...

Application of modem analytical procedures and physical methods for structure determination. In studies of microbial metabolism, the advantages resulting from the requirement for only extremely small quantities of material needed for gas- and liquid-chromatographic quantification, coupled to mass spectrometric identification, can hardly be overestimated.

The application of substrates isotopically labeled in specific positions makes it possible to follow the fate of individual atoms during the microbial degradation of xenobiotics. Under optimal conditions, both the kinetics of the degradation, and the formation of metabolites may be followed— ideally when samples of the labeled metabolites are available. Many of the classical studies on the microbial metabolism of carbohydrates, carboxylic acids, and amino acids used radioactive...

As might be expected, bacteria have been isolated from the plants that prodnce flnoroacetate, and these include an unidentified Pseudomonas sp. (Goldman 1965), a strain of Burkholderia Pseudomonas) cepacia from Dichapetalum cymosum (Meyer et al. 1990), and a strain of Morax-ella sp. (Kawasaki et al. 1981). In addition, fluoroacetate is an unusual product of microbial metabolism ...
