چکیده

A strain of Bacillus polymyxa produced a new peptide antibiotic complex, named LI-F, composed of more than ten components. The components, antibiotics LI-F03, F04, F05, F07, and F08 were isolated from the complex by reversed phase HPLC. They are active against fungi, yeasts, and Gram-positive bacteria. The fast atom bombardment mass spectra revealed that the individual isolated antibiotics are still mixture of two homologous components, being very difficult to separate from each other.

Studies on Polymyxin: Isolation and Identification of Bacillus polymyxa and Differentiation of Polymyxin from Certain Known Antibiotics.

Polymyxin is an antibiotic substance occurring in the culture filtrates of Bacillus polymyxa. The isolated substance is unique in its specificity for gram-negative bacteria. A summary of the more important results obtained during the course of several years, including chemotherapeutic and toxicity data, has been reported (Stansly, Shepherd, and White, 1947). The present contribution is concerne...

Isolation, identification and antimicrobial susceptibility of pathogenic Aeromonas media isolated from diseased Koi carp (Cyprinus carpio koi)

Aeromonas infections are the most common bacterial disease of cultured fish in China. In this study, a gram-negative bacillus was isolated from the liver of diseased koi carp (Cyprinus carpio koi), and named strain KC-2. The results of morphological and biochemical tests, as well as phylogenetic analysis derived from 16S rRNA and gyrB sequences indicated that the isolated strain KC-2 was highly...

Plipastatins: new inhibitors of phospholipase A2, produced by Bacillus cereus BMG302-fF67. I. Taxonomy, production, isolation and preliminary characterization.

Plipastatins have been isolated as part of a program designed to find inhibitors of porcine pancreatic phospholipase A2. They were purified from fermentation broth of Bacillus cereus BMG302-fF67 and finally separated into four fractions by reverse phase HPLC. The respective fractions were designated as plipastatins A1, A2, B1 and B2. Plipastatins also inhibited phospholipases C and D.
