Optimization of fermentation conditions for polysaccharide of Tricholoma matsutake using response surface methodology
摘要
Abstract
Response surface methodology was adopted to optimize fermentation conditions for polysac-charide of Tricholoma matsutake. Firstly, based on the results of carbon sources and nitrogen source experiments, a Plackett-Burman design was used to investigate the effects of different factors on production of polysaccharide, and three significant factors were corn flour, soybean meal, and KH2PO4. The path of steepest ascent was used to define optimal response region for these three factors. Optimal level combinations of factors were obtained through Box-Behnken design. The optimal fermentation conditions for polysaccharide of Tricholoma matsutake were as follows; corn flour 4. 54% , soybean meal 4. 96% , KH2PO4 0. 15% , MgSO4 -7H2O 0. 05% , VB1 0. 001% , initial pH 5.5, rotation speed 180 r/min, and fermentation time 10 d. Under optimal fermentation conditions, the yield of polysaccharide reached 5. 97 g/L.关键词
