Biological Detoxification of the Inhibitors in Corncob Acid Hydrolysate Using Aspergillus niger

The biological detoxification of lignocellulose hydrolysate is an effective method through which to enhance microbial fermentation efficiency. In this study, inhibitor-tolerant strain A. niger (Aspergillus niger) was used for the corncob hydrolysate. results showed that M13 can tolerate a concentration at least 7.50 ± 0.19 g/L acetic acid, 1.81 0.13 furfural, and 1.02 0.10 HMF (5-Hydroxymethylfurfural). spores had higher efficiency than mycelial pellets with rate 0.1566 g/L/h, 0.1125 0.015 g/L/h HMF, respectively. cell preferentially consumed then before simultaneously degrading acid glucose. could accumulate small amounts citric directly from undetoxified about 6 g/L. Therefore, serve as excellent potential fermenting when using lignocellulosic hydrolysates.
