Morphogenesis, Biomass and Oxytetracycline Production of Streptomyces rimosus in Submerged Cultivation

Streptomyces rimosus在浸沉培養時之形態化育、生質量與地靈黴素生產

摘要


以分光光度儀、HPLC和螢光素-螢光素酶法測定ATP時,其最低之檢出濃度分別為1.0μM,3.3μM和100nM。在浸沉培養65小時時,大部分之Streptomyces rimosus TM-55以菌絲片斷存在,培養168小時則形成短桿狀菌絲,而培養504小時則有部分菌絲被分解。培養24小時時其ATP含量最高,而後隨培養過程而逐漸降低。地靈黴素產量亦隨培養過程而增加,於166小時達最高力價178.9μg/ml而後逐漸下降。形態化育在Streptomyces浸沉培養生產地靈黴素時佔很重要之角色,短菌絲片段較有利於抗生素生產。

The minimal concentration of adenosine triphosphate (ATP) which could be detected with spectrophotometry, HPLC and luciferin-luciferase methods was 1.0μM, 3.3μM and 100nM, respectively. In submerged cultivation, most Streptomyces rimosus TM-55 was in hyphae fragment form at 65 h, became short-rod mycelia at 166 h, and lysed at 504 h incubation. The ATP content had maximal value at 24 h, then gradually decreased during cultivation. The oxytetracycline potency increased as incubation occurred, had maximal potency 178.9 μg/ml at 166 h, and then gradually decreased. Morphogenesis was very important in oxytetracycline production in submerged cultivation of Streptomyces; short-rod mycelia had high oxytetracycline production.
