摘要
Abstract
The effects of anthocyanin extracts from Lycium ruthenicum Murr on the growth of mycelium and synthesis of extracellular polysaccharide(EPS)were studied by adding them into the fermentation system of Agaricus bitorquis(Quél.)Sacc.Chaidam.The addi-tion method of anthocyanins and fermentation temperature were optimized,and the dynamic changes of residual sugar(reducing sugar)content,pH value and dissolved oxygen in the control system were studied.The study showed that compared with the blank control group,the extraction of anthocyanins of Lycium ruthenicum Murr was added in half flow(fermentation 0-36 h flow,the rate of 0.83 mL/min,the total amount of 1 800 mL)and cultured at variable temperature(23 ℃ for 0-36 h,25 ℃ for 36-96 h,23 ℃ for 96-120 h),my-celial biomass increased by 89.04％and polysaccharide yield increased by 65.46％.According to the established dynamic models of cell growth,EPS production and substrate consumption,the correlation coefficients of the fitting curves of the regulation group model were all＞0.93,indicating that the model could well reflect the fermentation process.Therefore,the anthocyanins of Lycium ruthenicum Murr can significantly promote the growth and synthesis of EPS of Agaricus bitorquis(Quél.)Sacc.Chaidam.This research provides theoretical sup-port for the large-scale development and application of the characteristic edible fungi on the Qinghai-Tibet Plateau.关键词
