چکیده انگلیسی
The current study suggests the utility of ZnO nanoparticles to increase the thermotolerance of phytase enzymes; thereby aiding their effective utilization to provide better phosphate uptake when applied in animal feeds. Microbial isolates with predominant phytase activity were isolated from industrial wastewater to obtain a promising thermotolerant isolate of Penicillium decumbens. The purified phytase showed activities at mash preparatory temperature (32.59â¯Â±â¯0.045â¯Umlâ1â¯minâ1 at 55â¯Â°C), animal feed pelletising temperature (37.83â¯Â±â¯0.127â¯Umlâ1â¯minâ1 at 80â¯Â°C) and steam sterilization temperature (18.56â¯Â±â¯0.027â¯Umlâ1â¯minâ1 at 100â¯Â°C) of animal feeds as per standard phytase assays. The supplementation of ZnO nanoparticles found to increase thermostability of phytase from 18.56â¯Umlâ1â¯minâ1 to 30.5â¯Umlâ1â¯minâ1 at 100â¯Â°C. The antibacterial role of the nanocomposites was checked against human pathogens to obtain satisfactory results against standard antibiotics. Thus the incorporation of ZnO nanoparticles in combination with phytase provided a dual benefit of increasing its thermostability and antimicrobial property thereby increasing its shelflife.
