New synthetic medium for growth of mycelium of Pleurotus species

The nutritional requirements of mycelial growth for Pleurotus spp. were studied. As the carbon sources, soluble starch and dextrin, nitrogen sources, arginine and ammonium tartrate, and calcium sources, enhanced mycelial growth. Optimum C/N ratio was 100 : 1. On the base of results from the experiment on nutritional requirements, the following receipe is suggested for growth of Pleurotus spp.; starch 15 g, arginine 3.484 g, ammonium tartrate 3.06 g, 0.314 g, 8.138 g, 1.584 g, 1.5 g for P. sajor-caju and 2.5 g for P. ostreatus. 0.02 g, 0.03 g, 0.02 g, optimum pH 6.0. This new synthetic medium is tentatively designated as Park's medium.
