Abstract
An actinobacterial strain designated as BN-6 was isolated from swallow bird mud nest by agar plate dilution method. It showed the morphological, physiological and biochemical characteristics of the genus Streptomyces. On the basis of 16S rRNA gene sequence analysis and physiological tests, this isolate was found to be most closely related with Streptomyces vinaceusdrappus NRRL2363. The strain BN-6 produced a broad spectrum active metabolite in Glucose Soybean meal (GS) medium and was extracted with HP Dianion resin. The resin extracted product showed activity against Gram-positive, Gram-negative bacteria, acid fast bacilli and fugal cultures, suggesting it broad spectrum characteristics. The bioautography on silica gel plates using Micrococcus luteus MTCC106 as test organism indicated the presence of a single metabolite having a Rf value of 3.2 and 9.1 in two different solvent systems. The characteristic peak obtained in UV–VIS spectrophotometer at 214 nm and chemical analysis indicates that it may be peptide class of metabolite.
