摘要
从黄天菊花、白背毛、苏黑、银白、正白、紫毛木耳7个黑木耳菌种中筛选产孢外多糖较多且生长较快的菌株紫毛木耳,并以紫毛木耳为菌种,研究了不同碳源、氮源、起始pH值和温度对其产孢外多糖的影响。结果表明,起始pH为6.0、温度25℃、酵母膏0.3%、葡萄糖2%,为产多糖较合适条件,每100ml培养液中多糖的量达74.5mg。
This article mainly studied the fermentaion condition producing extracellular polysaccharide by submerged fermenation of Auricularia auricula.An Auricolaria species which could produce more polysaccharide and grow well was screened.The conditions on producing polysaccharide would be different carbon source?nitrogen source?pH and temperature.It was concluded that pH6.0?25℃?0.3%yeast extract and 2%glucose were the optimum condions of producing polysaccgarude.
