9alpha-Fluorohydrocortisone is hydroxylated by Streptomyces roseochromogenes in the 16alpha-, the 2beta-, and in both the 16alpha- and 2beta- positions. 16alpha-Hydroxylation appears to be the more predominant and rapid pathway of transformation. The degree of 2beta-hydroxylation is dependent upon the strain used and may be increased to the point of its(More)
A new antibacterial antibiotic, designated LL-E19085 alpha, was isolated from the fermentation broth of an actinomycete strain. Based on cultural, physiological, morphological and chemical characteristics, culture LL-E19085 was identified as a new subspecies of Micromonospora citrea. Antibiotic LL-E19085 alpha demonstrated potent activity against a spectrum(More)
Antibacterial antibiotics LL-E19020 alpha and beta were isolated from the fermentation broth of an actinomycete strain. Based on cultural and physiological characteristics, culture LL-E19020 was identified as a new subspecies of Streptomyces lydicus. The LL-E19020 alpha and beta antibiotics were found to possess a very narrow antibacterial spectrum against(More)
Treatment of fragmented preparations of sarcoplasmic reticulum with diethyl ether decreases the calcium uptake capacity of reticulum, while the ATP-binding capacity as well as the ATP-splitting activity of reticulum were increased. Diethyl ether-treated reticulum preparations retained both the “basal” and the “extra” splitting activities of Hasselbach and(More)
The producing organism for the new broad spectrum glycocinnamoylspermidine antibiotics designated LL-BM123beta, gamma1 and gamma2 was characterized as a Nocardia sp. by chemical analysis of the cell wall, growth requirements, morphology and physiological reactions. Fermentation conditions to elaborate and analytical methods to characterize these antibiotics(More)
