Oxidation of Meloxicam by Streptomyces griseus
The aim of the present investigation was to biotransform the anti-inflammatory compound meloxicam by enzymes present in whole cells of five actinomycete cultures to produce novel bioactive derivatives. Among the actinomycetes screened, Streptomyces griseus NCIM 2622 was found to possess the enzyme system(s) that oxidize meloxicam into two metabolites whereas that present in S. griseus NCIM 2623...
متن کاملGenetic recombination in Streptomyces griseus.
Low-frequency (10(-6)) genetic recombination was observed in a cephamycin-producing strain of Streptomyces griseus. The recombinants were predominantly heteroclones. Heteroclone analysis was performed involving four heteroclones of one cross. In 100 mutants correlation was found between the type of auxotrophy and the level of antibiotic activity. A cross of this strain with a streptomycin-produ...
متن کاملStudies on the biochemistry of streptomyces. III. Glucose catabolism in Streptomyces griseus.
The operation of the tricarboxylic acid cycle and fixation of CO2 in Streptomyces griseus has recently been demonstrated in a series of tracer studies, Gilmour et al. (1955); Butterworth et al. (1955). As to the nature of the pathways of glucose catabolism in this organism, the operation of the Embden-Meyerhof glycolytic scheme and the direct oxidative pathway were indicated by inhibition studi...
متن کاملStudies on Streptomyces phage. I. Growth characteristics of the Streptomyces griseus host-phage system.
Within recent years, phages capable of infecting various Streptomyces species have been reported (Saudek and Colingsworth, 1947; Reilly et al., 1947; Koerber et al., 1950; Perlman et al., 1951; and Alexander and McCoy, 1956). Hoehn (1949) and subsequently Gilmour and Buthala (1950) demonstrated that streptomyces phage is indigenous to soil, the natural habitat of the host. The streptomyces host...
متن کاملCycloheximide production by Streptomyces griseus: alleviation of end-product inhibition by dialysis-extraction fermentation.
The use of dialysis fermentation with the continuous extraction of the dialysate has resulted in a twofold increase in the cycloheximide titer due to relief from product inhibition. Continuous extraction of the dialysate has eliminated the necessity for large reservoir volumes of fermentation medium normally used in dialysis fermentation. The apparatus used in this procedure is described.
