MFCs降解藻类生物质的预处理方法研究进展

open access: yesGongye shui chuli, 2022
微生物燃料电池(MFCs)能够在降解有机物的同时将化学能转化为电能,近年来其独特的能源环境效应在降解藻类生物质方面引起广泛关注。然而,成分复杂的藻类细胞壁会阻碍藻类生物质在微生物燃料电池中的降解。为了提高微生物燃料电池降解藻类生物质的效能,通常需要对藻类生物质进行预处理,破坏藻类细胞壁使生物基质释放,并将难降解的大分子有机物分解为易降解的小分子有机物。综述了目前应用于微生物燃料电池降解藻类生物质的预处理方法,包括机械法、加热法、微波法和超声波法等物理预处理法,酸、碱、氧化等化学预处理法,酶或微生物细胞 ...
