Candida tropicalis biofilm inhibition by ZnO nanoparticles and EDTA.

Objective: Biofilm of Candida tropicalis denote as a complex cellular congregation with major implication in pathogenesis. This lifestyle of fungus as a biofilm can inhibit immune system and antifungal therapy in treatment of infectious disease especially medical device associated chronic disease. In this study effects of Zinc Oxide (ZnO) nanoparticles and EDTA were evaluated on C.

A statistical approach for optimization of alkaline lipase production by ascidian associated- RSK CAS9.

A marine ascidian-associated bacterium, RSK CAS9, was optimized for lipase production by response surface methodology using marine waste as substrate. The central composite design was employed, and the optimal medium constituents for maximum lipase production (1355.81 U/ml) were determined to be tuna powder (14.
