The aim of this study was to optimize protease production using a novel Bacillus sp. ZR-5 strainisolated from the soil, and evaluate its application in detergent industry. The proteolytic activityof the strain was demonstrated using gelatin hydrolysis screening test. Protease productionoptimization was carried out using a two-step approach: a conventional method in order toidentify the best car...
Abstract : In-situ process is one of the biodiesel production methods in which seeds are used directly in the reaction without oil extraction. The objective of this research is to optimize the biodiesel production conditions for the in-situ reaction using tomato seeds as a feed. The effects of reaction parameters such as molar ratio of oil to alcohol and catalyst to oil weight percent ratio on ...
Due to the importance of Bacillus thuringiensis (Bt) in the biological fight, it is necessary to optimize its fermentation process and decrease its production cost. Statistical analysis is used not only to optimize fermentation conditions but also to describe and predict the culture behavior. In production of biological insecticide, one of the important phases is named as sporulation upon which...
Introduction: The need for food produced from animal husbandry has made it a growing industry which result in increment of livestock waste. On the basis of environmental and economic considerations, these materials require treatment and management. Anaerobic digestion and creation of biogas are the most effective methods of waste management. Several parameters affect the anaerobic digestion of ...
The present research studies the performance of Converter Sludge (CL)as a nano-activator of persulfate (PS) in Permeable Reactive Barrier (PRB) as an in-situ technology for leachate treatment.In batch experiments, the acidic conditions (pH = 3) have been the most suitable for removal operations, where COD and NH3 removal efficiencies are 69.15% and 60.96%, respectively. The Box–Behnken design (...
