富锗酵母生产工艺的优化
Optimization conditions on germanium-enriching yeast production
【摘要】 以啤酒酵母为生产菌种、麦芽汁玉米浆为培养基,在发酵液中添加GeO2,通过生物富集作用生产富锗酵母。由正交试验得出生产富锗酵母的最佳工艺条件,即在麦芽汁培养基中添加3%玉米浆,100mg/kgGeO2,糖度10°Bx,发酵时间为24h,锗含量达978.4μg/g。
【Abstract】 Germanium-enriching yeast was obtained through bio-enrichment using Saccharomyces cerevisiae as initial strains,wort-corn paste with GeO2 were used as medium.The optimum conditions for gemanium-enriching yeast production were obtained through orthogonal experiment: 3% corn paste and 100 mg/kg GeO2 were added into wort medium,sugar content was 10°Bx,the content of Ge reached to 9784.μg/g after fermenting for 24 h.
