|
For the production of mycelia of mushroom by submerged culture, the experiment was carried out. mushroom. The optimum culture broth for Ganoderma lucidum NG-L were composed of CMC 0.8%(w/v) and (NH₄)₂SO₄ 0.2%, with 10%(v/v) of inoculum size and pH 5.5 when the milk whey was used as basal medium. In case of Grifola frondosa ATCC48688, the optimum broth were composed of soluble starch 2%(w/v) and KNO₃ 0.1%(w/v), with 8%(v/v) of inoculum size and pH 5.2. Among several plant growth hormones, indole-3-acetic acid and gibberellin A₃-3acetate stimulated the mycelial growth of Ganoderma lucidum NG-L and Grifola frondosa ATCC 48688 respectively. The culture broth of these mushrooms inhibited the growth of B. subtilis and P. aeruginosa.
