Screening and identification of exopolysaccharide-producing yeasts
产胞外多糖酵母菌株的筛选鉴定及发酵产糖

Objective] Most of microbial extracellular polysaccharide(EPS) has the favorable functionality and peculiarity,but little research has been done about EPS that were synthesized by yeasts.Screening of EPS-producing yeasts and studies on the optimal culture composition are the main purpose of this study.Methods] Yeasts were obtained by screening from natural samples using spread-plate method,Yield of EPS synthesized by yeasts was estimated by phenol-sulfate acid method,Based on 5.8S rDNA sequence determinat...
