15 صفحه اولStructure and Antibacterial Activity of Ambobactin, a New Telomycin-Like Cyclic Depsipeptide Antibiotic Produced by Streptomyces ambofaciens F3.
A new telomycin-like cyclic depsipeptide, ambobactin (1), was isolated from the metabolites of Streptomyces ambofaciens F3, an endophyte of Platycladus orientalis. Its structure was elucidated on the basis of extensive spectroscopic analysis and advanced Marfey's method. Ambobactin is structurally related with telomycin, except that the configuration of the 3-methyltryptophanes in their structu...
متن کاملStudy on Activity and Stability of Proteases from Bacillus Sp. Produced by Submerged Fermentation
Objective: Investigations were carried out to isolate bacteria from saline-alkali soils and determined optimized alkaline protease activity and stability produced by a wild strain of bacillus sp. in submerged fermentation (SMF). Methods: Optimum temperature for enzyme activity in the crude extract was 40 ◦C at a pH between 8.0 and 9.0. The studies on pH stability showed that the enzyme...
