Mixed Fermentation of G.lucidum XinZhi and Flammulina velutipes for High-yield Zinc Production
摘要
Abstract
Glucidum XinZhi and Flammulina velutipes were used as the original strains for mixing fermentation to discuss technology conditions of high-yield zinc. Quality of zinc from mycelium was determined by atomic absorption spectrum method. The results showed that the best medium was 2% starch, 2% potato, 1% sucrose, 2% com meal, and 1% soybean meal. The optimal fermentation conditions were cultured time 8 days, temperature 27 ℃, shaking speed ISO r/min, and medium volume 100 mL/250mL. Quality of intracellular zinc was 45.6 mg/kg at above optimal conditions, 15.8% and 63.5% higher than that by Glucidum XinZhi and Flammulina velutipes respectively. Therefore mixed fermentation had a more complete process, higher availability of nutrition, promising growth and more quality of intracellular zinc.关键词
