Actinomycete strains OM-6519(T) and K04-0144(T) produce the bioactive compounds lactacystin and cyslabdan, respectively. Here, the taxonomic positions of these two strains were determined. The morphological and chemical features of strains OM-6519(T) and K04-0144(T) indicated that they belonged ...
Fluoroquinolones are antimicrobial agents that are widely used clinically, but the increasing resistance of Acinetobacter baumannii (A. baumannii) to these agents is a matter of concern. We investigated mutant prevention concentrations (MPCs) of three fluoroquinolones, levofloxacin (LVX), pazufl...
Two new hydroanthraquinones, paradictyoarthrins A (1) and B (2), were isolated from the mangrove-derived fungus Paradictyoarthrinium diffractum BCC 8704. Structures of the new compounds were elucidated by analyses of the NMR spectroscopic and mass spectrometry data. The absolute configuration of...
A moderate growing strain designated as MPKL 26(T) was isolated from a soil sample of Bidar Fort, Karnataka, India. The strain MPKL 26(T) was Gram positive, bent rod in shape. The optimum pH and temperature for growth was 7.0 and 30 °C, respectively. The 16S ribosomal RNA gene sequence analysis ...
Vancomycin, a glycopeptide antibiotic, has long been a drug of choice for life-threatening Gram-positive bacterial infections. Vancomycin confers its antibacterial activity by inhibiting bacterial cell wall biosynthesis. However, over the time, vancomycin has also been rendered ineffective by va...
Gram-positive bacteria can cause various infections including hospital-acquired infections. While in the biofilm, the resistance of bacteria to both antibiotics and the human immune system is increased causing difficulties in the treatment. Bacillus subtilis, a non-pathogenic Gram-positive bacte...
