“The marine strain Pseudomonas otitidis was isolated to hydrolyze

the cooked sunflower oil (CSO) followed by the production of lipase. The optimum culture conditions for the maximum lipase production were determined using Plackett-Burman design and response surface methodology. The maximum lipase production, 1,980 U/ml was achieved at the optimum culture conditions. After purification, an 8.4-fold purity of lipase with specific activity of 5,647 U/mg protein and molecular mass of 39 kDa was obtained. The purified lipase was stable at pH 5.0-9.0 and temperature 30-80 A degrees C. Ca2+ and Triton X-100 showed stimulatory effect on the lipase activity. The purified lipase was highly stable in the non-polar solvents. The functional groups of the lipase were determined by Fourier transform-infrared 17DMAG (FT-IR) spectroscopy. The purified lipase showed higher hydrolytic activity towards CSO over the other cooked oil wastes. About 92.3 % of the CSO hydrolysis was observed by the lipase at the optimum time 3 h, pH 7.5 and temperature 35 A degrees C. The hydrolysis of CSO obeyed pseudo first selleck inhibitor order rate kinetic model. The thermodynamic properties of the lipase hydrolysis were studied using the classical Van’t Hoff equation. The hydrolysis of CSO was confirmed by FT-IR studies.”
“The

heat shock protein 70 (Hsp70) family members function as ATP-dependent molecular chaperones that assist in the folding of newly synthesized polypeptides and in the refolding of misfolded/aggregated Selleck AZD5153 proteins. These heat shock proteins comprise at least eight sets of molecular groups that share high homology, but differ from each other in their expression level and subcellular localization. Hsp72, which is also known as Hsp70 and Hsp70-1, is localized mainly in the cytoplasm but is also found in the nucleus. Stress-induced Hsp72 functions as a chaperone enabling the cells to cope with harmful

aggregations of denatured proteins during and following stress. The difference in the function of Hsp72 from that of other Hsp70 members, however, remains unclear. We report the establishment of a monoclonal antibody specific for Hsp72 using the rat medial iliac lymph node method. Immunoblot analysis revealed that our monoclonal antibody against Hsp72 specifically identified the 65 kDa protein. Immunocytochemical staining also revealed that Hsp72 localized in the cytoplasm and nucleus, and aggregated in the nucleus in response to heat stress. This MAb against Hsp72 will allow for further studies to elucidate the mechanism by which Hsp72 is localized in the cell in response to stress stimuli, and aid in the identification of specific interacting molecules.”
