摘要

Abstract

The liquid-state fermentation conditions for β-1,3-1,4-glucanase production by Aspergillus awamori CAU33,a fungal strain isolated from soil sample,were optimized using a combination of one-factor-at-a-time method and response surface methodology.The highest β-1,3-1,4-glucanase activity of 8 447 U/mL was achieved after 6 days of culture at 35 ℃ in a medium consisting of corncob 55 g/L,soybean peptone 25 g/L,and Triton X-114 23 g/L at an initial pH of 4.5,about 17.6 times higher than before the optimization.
