Then the fermentation kinetics of enzyme production was studied. The results show that with the addition of FWH to the fermentation medium with a final concentration of 4% (optimal concentration), alkaline protease value reached a maximum value (89 U/ml), which is 63% higher than that of the control medium.  Also fermentation kinetics of alkaline protease by isolated Bacillus sp. was studied. Several kinetic models were evaluated; the combination of the Moser and Boulton kinetic model gave the best prediction. This nonlinear mathematical model performed satisfactory on biomass, substrate, and enzyme predictions.}, keywords = {Alkaline protease,Fish waste hydrolysate,Modeling,Bacillus}, url = {https://www.ije.ir/article_72523.html}, eprint = {https://www.ije.ir/article_72523_995af2816015540775c4ffa78febdee5.pdf} }
