production of avermectin b1b from streptomyces avermitilis 41445 by batch submerged fermentation
results however the maximum production of avermectin b1b (17 mg/l) was obtained by using sm2 growth medium containing soluble corn starch, yeast extract, kcl, caco3 and mgso4 which was detected qualitatively by using tlc and quantitatively by hplc. conclusions maximum production was observed with initial medium ph of 7, 10% inoculum size with incubation temperature of 31°c for 10 days of fermen...
متن کاملProduction and Screening of High Yield Avermectin B1b Mutant of Streptomyces avermitilis 41445 Through Mutagenesis
BACKGROUND Secondary metabolite production from wild strains is very low for economical purpose therefore certain strain improvement strategies are required to achieve hundred times greater yield of metabolites. Most important strain improvement techniques include physical and chemical mutagenesis. Broad spectrum mutagenesis through UV irradiation is the most important and convenient physical m...
متن کاملproduction and screening of high yield avermectin b1b mutant of streptomyces avermitilis 41445 through mutagenesis
conclusions: the hereditary stability analysis of the uv mentioning 45 minutes revealed the uv exposure time for mutants and 3 represented the colony taken from the plate irradiated for 45 minutes mutant showed that the production of avermectin b1b remained constant and no reverse mutation occurred after 15 generations. results: avermectin b1b-hyper-producing mutant, produced using these three ...
متن کاملSignificance of Heavy-Ion Beam Irradiation-Induced Avermectin B1a Production by Engineered Streptomyces avermitilis
Heavy-ion irradiation technology has advantages over traditional methods of mutagenesis. Heavy-ion irradiation improves the mutation rate, broadens the mutation spectrum, and shortens the breeding cycle. However, few data are currently available regarding its effect on Streptomyces avermitilis morphology and productivity. In this study, the influence of heavy-ion irradiation on S. avermitilis w...
متن کاملIsolation, Characterization and Selection of Avermectin-Producing Streptomyces avermitilis Strains From Soil Samples
BACKGROUND Streptomyces avermitilis, belonging to Actinomycetes, is specialized for production of avermectin, used as an anthelmintic and insecticidal agent. It is mostly found in soil and its isolation is very crucial for medically important avermectin production. OBJECTIVES In the present study, 10 bacterial isolates lacking antimicrobial activities were isolated from the soil samples colle...
