Antibiotics produced by Streptomyces.
Streptomyces is a genus of Gram-positive bacteria that grows in various environments, and its shape resembles filamentous fungi. The morphological differentiation of Streptomyces involves the formation of a layer of hyphae that can differentiate into a chain of spores. The most interesting property of Streptomyces is the ability to produce bioactive secondary metabolites, such as antifungals, a...
متن کاملThe structures of atpenins A4, A5 and B, new antifungal antibiotics produced by Penicillium sp.
The structures of atpenins A4, A5 and B, new antifungal antibiotics produced by Penicillium sp., have been deduced to be I, II and III, respectively, on the basis of spectroscopic and 1H and 13C NMR spectral data. The molecular structure of atpenin A4 with absolute configurations was finally confirmed to be 2'S,4'S,5'S-5,6-dimethoxy-4-hydroxy-5'-chloro-2',4'- dimethyl-1'-oxoheptyl-2-hydroxypyri...
متن کاملAtpenins, new antifungal antibiotics produced by Penicillium sp. Production, isolation, physico-chemical and biological properties.
Penicillium sp. FO-125, a soil isolate, was found to produce a new antifungal antibiotic complex named atpenin. Three components A4, A5 and B were isolated from the fermentation broth of the producing strain by solvent extraction, silica gel column chromatography and HPLC. The molecular formula of atpenins A4, A5 and B were determined to be C15H22NO5Cl, C15H21NO5Cl2 and C15H23NO5, respectively,...
متن کاملIdentification of some secondary metabolites produced by four Penicillium species
Fungi produce a wide range of secondary metabolites such as antibiotics, toxins, alkaloids, fatty acids, ketones and alcohols during active cell growth. The present study was aimed to identify secondary metabolites from some Penicillium species, using GC-MS. Many important compounds such as 3-oxoquinuclidine in Penicillium jenseii, formamidine in Penicillium pusillum, orcinol and 1,3,8-p-mentha...
متن کاملMycotoxins and other secondary metabolites produced in vitro by Penicillium paneum Frisvad and Penicillium roqueforti Thom isolated from baled grass silage in Ireland.
Secondary metabolites produced by Penicillium paneum and Penicillium roqueforti from baled grass silage were analyzed. A total of 157 isolates were investigated, comprising 78 P. paneum and 79 P. roqueforti isolates randomly selected from more than 900 colonies cultured from bales. The findings mostly agreed with the literature, although some metabolites were not consistently produced by either...
