New polyene antifungal antibiotic produced by a species of Actinoplanes.
A new species of Actinoplanes, which has been deposited with the designation NRRL 5325 at the Northern Utilization Research and Development Division of the U. S. Department of Agriculture, produces a polyene antifungal complex designated as Sch 16656. The complex, consisting of one major and three minor components, is isolated from the fermentation broth by a solvent extraction procedure and pu...
متن کاملBE-40665D, a new antibacterial antibiotic produced by an Actinoplanes sp.
In the course of our screening program for new antibacterial substances, an Actinoplanes strain A40665 isolated from a soil sample collected in Oita Prefecture, Japan, was found to produce an active compound. This compound, BE-40665D, was isolated from the mycelial cake of culture broth and the structure was elucidated as shown in Fig. 1. BE-40665D inhibited the growth of Gram-positive bacteria...
متن کاملAcrebol, a novel toxic peptaibol produced by an Acremonium exuviarum indoor isolate.
AIMS To identify a toxin and its producer isolated from woody material in a building where the occupants experienced serious ill health symptoms. METHODS AND RESULTS Hyphal extracts of an indoor fungus, identified as the cycloheximide-tolerant species Acremonium exuviarum, inhibited motility of boar spermatozoa (EC(50) 5 +/- 2 microg of crude solids ml(-1)) and caused cytolysis of murine neur...
متن کاملInfluence of Additives on the Yield and Pathogenicity of Conidia Produced by Solid State Cultivation of an Isaria javanica Isolate
Recently, the Q biotype of tobacco whitefly has been recognized as the most hazardous strain of Bemisia tabaci worldwide, because of its increased resistance to some insecticide groups. As an alternative control agent, we selected an Isaria javanica isolate as a candidate for the development of a mycopesticide against the Q biotype of sweet potato whitefly. To select optimal mass production med...
متن کاملCharacterization of a novel AmpC β-lactamase produced by a carbapenem-resistant Cedecea davisae clinical isolate.
A Cedecea davisae isolate, which was intermediate or resistant to third-generation cephalosporins and carbapenems, was recovered from a urine sample. Susceptibility testing, isoelectric focusing, and analysis of outer membrane proteins showed that AmpC β-lactamase expression combined with porin deficiency accounted for the carbapenem resistance. A cloning experiment followed by phenotypic and e...
