4). The isolate was gram positive and spore forming bacteria. Other biochemical properties have been given below (Table 1) The isolate produced a white opaque zone surrounding it (Fig. 5) and also observed iridescent of light that confirmed lecithinase and lipase activity respectively. Hemolysis of the red cells (Fig. 6a) suggested the possibility of production Dasatinib of any biosurfactant.26 Surface tension of the culture medium decreased with time (Fig. 6b). This proved the production of any surfactant molecule by the isolate

during its metabolism. The isolate showed high gelatinase activity which was evident from zone of clearance (Fig. 7). There have been reports that high protease activity (gelatinase is a matrix metalloproteinase) may be potential candidates for use as insecticidal agents.27 Phylogenetic tree (Fig. 8) based on neighbor-joining method showed the isolate was a new strain of Bacillus weihenstephanensis. It was named as B. weihenstephanensis strain AN1. The area of Haldia Refinery has been enriched with polycyclic aromatic hydrocarbon degrading bacteria. B. weihenstephanensis strain AN1 was chosen for further as it was able to degrade PAHs like benzo[a]pyrene, anthracene, fluoranthene and pyrene considerably. FDA-approved Drug Library datasheet The isolate produced amylase, lipase, biosurfactant and other biochemicals. It showed high gelatinase activity.

A new bacterial strain has been isolated and identified that may be used for removal of oil or PAH contaminated soil or water. The isolate may find its application for production of industrially important biochemicals like lipase, amylase and biosurfactant. The bacteria may be tested GPX6 further for its use in pest control. All authors have none to declare. “
“Staphylococcus aureus is a Gram positive pathogen that causes a wide variety of diseases

in humans, ranging from local soft-tissue infections to life-threatening septicaemia. S. aureus causes disease by producing many extracellular virulence factors, including several proteases, lipases, hemolysins, superantigens and cell wall associated adherence proteins. As with many pathogens, maximal expression of S. aureus virulence factors occurs during the post-exponential phase of growth. 1 One of the defence mechanisms of S. aureus is the capacity to form biofilms. Bacteria embedded in biofilms are often difficult to eradicate with standard antibiotic regimens and inherently resistant to host immune responses. 2, 3 and 4S. aureus can colonize at any biotic and a biotic anatomical locales, this is due to production of cell wall associated adherence proteins and virulence factor. Glycolysis is a major pathway in S. aureus 85% of the glucose is consumed through EMP pathway. 5 The extensive growth in glucose enhanced glycolysis suppressed the TCA cycle, decreases the activity of pentose cycle and suppressed the formation of many enzymes even the oxidation of pyruvic acid was decreased in glucose grown organism.
