摘要
秸秆稀酸水解过程会产生甲酸、乙酸、乙酰丙酸、糠醛、酸溶木质素等副产物,其存在会对后续微生物发酵过程产生严重的负面影响。因此,秸秆稀酸水解液的脱毒处理是必不可少且重要的环节。本文从秸秆稀酸水解液中发酵抑制物的产生、类型、抑制机理和稀酸水解液脱毒方法进行综述,重点介绍了最具有工业应用前景的脱毒技术——吸附树脂在秸秆稀酸水解液脱毒中的应用进展。
During the process of straw dilute-acid hydrolysis,by-products such as formic acid,acetic acid,levulinic acid,furfural and acid-soluble lignin will be inevitably produced,which will have a serious negative impact on the subsequent microbial fermentation process.Therefore,detoxification of the hydrolysate is an essential and important step for microbial fermentation.In this paper,the production,types and inhibition mechanism of fermentation inhibitors in dilute acid hydrolysate of straw were reviewed,and the detoxification methods of dilute acid hydrolysate of straw were summarized.On this basis,the application of adsorbent resin in detoxification of dilute acid hydrolysate of straw was introduced.
