A new cyclic lipopeptide antibiotic, enamidonin.
Wehave been screening microbial fermentation for inhibitors of mitogenic activity of epidermal growth factor1?2). During the screening, a new lipopeptide antibiotic, enamidonin (Fig. 1) which shows detransforming activity of a rat cell line transformed with a temperature sensitive Rous sarcoma virus (src^-NRK cells), has been isolated from a culture broth of Streptomyces sp. 9 1 -75. The produc...
متن کاملPurification and Characterization of a Major Extracellular Chitinase from a Biocontrol Bacterium, Paenibacillus elgii HOA73
Chitinase-producing Paenibacillus elgii strain HOA73 has been used to control plant diseases. However, the antimicrobial activity of its extracellular chitinase has not been fully elucidated. The major extracellular chitinase gene (PeChi68) from strain HOA73 was cloned and expressed in Escherichia coli in this study. This gene had an open reading frame of 2,028 bp, encoding a protein of 675 ami...
متن کاملIn vitro and in vivo activity of LY 146032, a new cyclic lipopeptide antibiotic.
The in vitro activity of LY 146032, a cyclic lipopeptide antibiotic belonging to the class of agents designated A21978C, was compared with those of vancomycin, cefpirome, cefotaxime, and clindamycin against selected gram-positive bacteria. The new drug inhibited all staphylococcal isolates, including methicillin-resistant strains, at concentrations of less than or equal to 1.0 microgram/ml. The...
متن کاملThe Profile and Antimicrobial Activity of Bacillus Lipopeptide Extracts of Five Potential Biocontrol Strains
In this study the efficacy of two different methods for extracting lipopeptides produced by five Bacillus strains-ethyl acetate extraction, and acid precipitation followed by methanol extraction-was investigated using mass spectrometry. High performance thin layer chromatography (HPTLC) was also used for the simultaneous separation of complex mixtures of lipopeptide extracts and for the determi...
