Resumo
Extracellular β-1,3-glucanase was produced by Trichoderma harzianum Rifai cultivated in the Agaricus blazei (Agaricus brasiliensis) extract as a substrate in submerged fermentation. A 22-central composite factorial design was developed using the time of culture (x1/day) and Agaricus blazei extract concentration (x2/(g/L)) as variables, and the results were analyzed using response surface methodology (RSM). The results showed that the Agaricus blazei extract concentration was the most important variable in the production of β-1,3-glucanase, and the maximum β-1,3-glucanase activity (0.77 U/mL) was obtained in one day of cultivation. The β-glucan present in the cell wall of Agaricus blazei mushroom proved to be a good substrate for inducing the production of specific β-1,3-glucanase by Trichoderma harzianum Rifai.
