چکیده
Enterocin is a new antibiotic isolated from cultures of two strains of Streptomyces, which were given the names Streptomyces candidus var. enterostaticus WS-8096 and variant M-127 of Streptomyces viridochromogenes. Its elementary analysis and mass spectroscopic measurement suggest the molecular formula is C22H20010. The ultraviolet absorption gave two maximal peaks at 250 nm and 283 nm in methanol. Enterocin has static activities against gram-positive and gram-negative bacteria and no activity against fungi and yeast.

Capuramycin, a new nucleoside antibiotic. Taxonomy, fermentation, isolation and characterization.
A new antibiotic capuramycin was isolated from the culture filtrate of Streptomyces griseus 446-S3 by adsorption and partition column chromatography. Based on its chemical structure being an uracil nucleoside with a caprolactam substituent, this substance was named as capuramycin. This paper describes the taxonomy of a producing organism, fermentation, isolation, characterization and biological...

A new antibiotic, cyanocycline A, was isolated from the fermentation broth of Streptomyces flavogriseus strain No. 49, a soil isolate. The molecular formula of cyanocycline A was determined to be C22H26N4O5. The antibiotic has a cyano group and a N-heterocyclic quinone moiety in its structure. Cyanocycline A was found to have broad spectrum antimicrobial and antitumor activity.
متن کاملAntibiotic G-418, a new Micromonospora-produced aminoglycoside with activity against protozoa and helminths: fermentation, isolation, and preliminary characterization.
Antibiotic G-418 is a new aminoglycoside produced as the major component by a new species of Micromonospora, M. rhodorangea NRRL 5326. The antibiotic is prepared by submerged fermentation in a soybean-dextrin medium. Antibiotic G-418 is adsorbed on a cationic-exchange resin and separated from other impurities by passing it down a Dowex (1 x 2) resin column. The antibiotic, which contains 2-deox...

Lavendomycin, a new basic peptide antibiotic containing novel amino acids, has been isolated from the culture broth of a streptomyces designated as Streptomyces lavendulae subsp. brasilicus. The antibiotic obtained as colorless crystals (C29H50N10O8, MW 666) is active against Gram-positive bacteria in vitro and in vivo, however, inactive against Gram-negative bacteria and fungi. An acute toxici...
