通过考察不同糠醛浓度对米根霉 (Rhizopus oryzae LS-1) 发酵产乳酸过程中糖酸转化率和糖利用率的影响, 探索了解Rhizopus oryzae LS-1对木质纤维水解副产物糠醛抑制物的耐受性, 寻找Rhizopus oryzae LS-1对糠醛抑制物的耐受浓度. 结果表明: Rhizopus oryzae LS-1对糠醛的耐受浓度为12.5g/L, 在0~12.5g/L可提高糖酸转化率和糖利用率. 当糠醛浓度大于12.5g/L时, 菌株生长完全受到抑制. 研究结果对乳酸生产用木质纤维素水解液的脱毒处理工艺具有指导作用.
通過攷察不同糠醛濃度對米根黴 (Rhizopus oryzae LS-1) 髮酵產乳痠過程中糖痠轉化率和糖利用率的影響, 探索瞭解Rhizopus oryzae LS-1對木質纖維水解副產物糠醛抑製物的耐受性, 尋找Rhizopus oryzae LS-1對糠醛抑製物的耐受濃度. 結果錶明: Rhizopus oryzae LS-1對糠醛的耐受濃度為12.5g/L, 在0~12.5g/L可提高糖痠轉化率和糖利用率. 噹糠醛濃度大于12.5g/L時, 菌株生長完全受到抑製. 研究結果對乳痠生產用木質纖維素水解液的脫毒處理工藝具有指導作用.

Through studying effects of glucose acid conversion rate and glucose utilization rate on different furfural concen-tration, tolerance of Rhizopus oryzae LS-1 on furfural inhibitor in lignocelluloses hydrolysates were explored, and tolerance con-centration was searched. Results showed that tolerance threshold for Rhizopus oryzae LS-1was 12.5g/L, when furfural was indi-vidually added. Yield of lactic acid increased when furfural concentration was lower than 12.5g/L. quantitative view to the lactic acid production under the inhibition of lignocellulose degradation products were gave, and it has some guiding significances for overcome the difficulties of the lignocellulosic hydrolysates fermentation.
