摘要
选择法国面包酵母为菌种,在高锌条件下进行90代的适应性培养,获得了具有较高产率的富锌酵母株,含锌量4000～15000μ/g。对该株酵母的最适生长条件(无机锌浓度、菌种接种量、酸碱度、碳源、氮源)及小鼠急性毒性进行了研究。
The French bread yeast(Saccharomyces ceyevlsiae) with comparatively high productivity and zinc content was subjected to adaptive culture under high zinc concentration. After ninety generations'culture of the yeast, its zinc content was 4000～15000μg/g.Its growth conditions was researched, including concentration of inorganic zinc, amount of inoculation, pH, carbon and nitrogen sources. Its acute toxicity in mice was also investigated.
