Abstract

|
|
The effectiveness of three kinds of enzymes (chitinase, β-glucuronidase, and lysing enzyme complex), employed aselicitors to enhance the β-glucan content in the sawdust-based cultivation of cauliflower mushroom (Sparassis latifolia), wasexamined. The elicitors were applied to the cauliflower mushroom after primordium formation, by spraying the enzyme solutionsat three different levels on the sawdust-based medium. Mycelial growth was fully accomplished by the treatments, but themetabolic process during the growth of fruiting bodies was affected. The application of a lysing enzyme resulted in an increase inthe β-glucan concentration by up to 31% compared to that of the control. However, the treatment resulted in a decrease inmushroom yield, which necessitated the need to evaluate its economic efficiency. Although we still need to develop a moreefficient way for using elicitors to enhance functional metabolites in mushroom cultivation, the results indicate that the elicitationtechnique can be applied in the cultivation of medicinal/edible mushrooms.
