Mycocerein, a novel antifungal peptide antibiotic produced by Bacillus cereus.
A peptide was obtained from culture filtrates of a bacterium which was newly isolated and tentatively named Bacillus cereus SW. The peptide was composed of Asx, Ser, Glx, Leu, Tyr, Pro, and an unknown amino acid in a ratio of 2:1:1:1:1:1:1, but, unless hydrolyzed with HCI, it was ninhydrin reaction negative. The peptide effectively inhibited the growth of all fungi and yeasts so far examined, w...
متن کاملPrumycin produced by Bacillus cereus.
The isolation of prumycin from cultured broths of Streptomyces kagawaensis has been reported by HATA et al.') It inhibits the growth of some bacteria and fungi,') and shows antitumor action.') The structure determined by OMURA et al.3,4) to be 4-D-alanylamino-2-amino-2,4-dideoxy-Larabinose. We isolated this antibiotic from cultured broths of a strain BMG366-UF5 which was isolated from a soil sa...
متن کاملYM-47522, a novel antifungal antibiotic produced by Bacillus sp. II. Structure and relative stereochemistry.
YM-47522 (1) was isolated from the fermentation broth of Bacillus sp. YL-03709B as an antifungal antibiotic. The structure of 1 was elucidated by spectroscopic analyses. YM-47522 (1) consisted of C13 carboxylic acid amide and cinnamate moieties. The relative stereochemistry was also proposed on the basis of chemical transformation into a 1,3-diol acetonide and its NMR data.
متن کاملCepacidine A, a novel antifungal antibiotic produced by Pseudomonas cepacia. II. Physico-chemical properties and structure elucidation.
Cepacidine A is a novel glycopeptide with a potent antifungal activity, which is produced by Pseudomonas cepacia AF 2001. Its molecular weight was determined by FAB-MS (m/z 1215). The compound is comprised of glycine (1), serine (2), 2,4-diaminobutyric acid (1), aspartic acid (1), beta-hydroxy tyrosine (1), beta-hydroxy asparagine (1), xylose (1) and 5,7-dihydroxy-3,9-diamino-octadecanoic acid ...
متن کاملIsolation and identification of Bacillus cereus of dry bulk and packaged vegetables by culture and PCR
Background: Bacillus cereus is an endemic, Gram-positive, rod-shaped, motile, beta hemolytic bacterium. Some strains are harmful to humans and cause foodborne illness and it's spore is resistant against difficult condition In recent years life style and feeding habits have changed and an increase in the use of ready to eat product has raised concern about quality and health assessment. Dehydrat...
