Overproduction of Clavulanic Acid by UV Mutagenesis of Streptomyces clavuligerus
Clavulanic acid is produced industrially by fermentation of Streptomyces clavuligerus and researches have increased its production by strain improvement, recombinant DNA technology, and media composition and growth condition optimization. The main objective of this study was to increase the level of clavulanic acid production from Streptomyces clavuligerus (DSM 738), using UV irradiation. After...

متن کاملpcd mutants of Streptomyces clavuligerus still produce cephamycin C.
Biosynthesis of cephamycin C in Streptomyces clavuligerus involves the initial conversion of lysine to alpha-aminoadipic acid. Lysine-6-aminotransferase and piperideine-6-carboxylate dehydrogenase carry out this two-step reaction, and genes encoding each of these enzymes are found within the cephamycin C gene cluster. However, while mutation of the lat gene causes complete loss of cephamycin pr...
متن کاملRegulation of nitrogen catabolic enzymes in Streptomyces clavuligerus.
The levels of several enzymes involved in assimilation of different nitrogen compounds were investigated in Streptomyces clavuligerus in relation to the nitrogen source supplied to the cultures. Threonine dehydratase, serine dehydratase, proline dehydrogenase, histidase and urocanase were not decreased in the presence of ammonium. The latter two enzymes were induced by histidine in the culture ...
