米根霉孢子凝聚条件的研究
Research on Rhizopus oryzae spore aggregation
摘要
Abstract
Rhizopus oryzae,as an important industrial microorganism,its morphology had large influence on product production.In this research,the effects of pH and glucose concentration of culture medium on spores aggregation were investigated.The zeta potential and hydrophobicity of spores at different swelling time were tested for spore aggregation.The spore aggregation ratio reached 88.62 ％ under the conditions of pH 3.0,320 g/L glucose,34 ℃,200 r/m.As a result,the pelletization way of Rhizopus oryzae was switched to coagulative way,which provided a solid base for filamentous fungal morphology control,especially for Rhizopus oryzae.关键词
