| 摘要: |
| 为了对富铬酵母的工业化生产提供参考依据,用活性干酵母为菌种制备富铬酵母,通过单因素试验和正交试验,以富铬酵母中有机铬总量为指标,确定了富铬酵母的优化发酵条件为:Cr3+质量浓度300 μg/mL,接种量120 mL/L,pH 6.5,培养时间28 h,装液量280 mL/L,发酵温度28 ℃。 |

| Abstract: |
| In ordr to provide reference for the industrial production of chromium enriched yeast by angel active yeast,by using single factor tests and a L18(37) orthogonal design,and analysed by the total organic Cr of chromium enriched yeast,the fermentation conditions were optimized as:culture volume was 280 mL/L,300 μg/mL Cr3+ and 120 mL/L inoculation at 28 ℃ for 28 h at 200 r/min,with the initial pH adjusted to 6.5. |
