Hydrogen production from biological processes has been hailed as a promising strategy for generating sustainable energy. Fermentative hydrogen production processes such as dark and photofermentation are considered more sustainable and economical than other biological methods such as biophotolysis. However, these methods have constraints such as low hydrogen yield and conversion efficiency, so practical implementations still need to be made. The present review provides an assessment and feasibility of producing biohydrogen through dark and photofermentation techniques utilizing various lignocellulosic biomass wastes as substrates. Furthermore, this review includes information about the strategies to increase the productivity rate of biohydrogen in an eco-friendly and sustainable manner, like integration of dark and photofermentation techniques, pretreatment of biomass, genetic modification of microorganisms, and application of nanoadditives.
生物制氢被誉为一种产生可持续能源的有前景的策略。诸如暗发酵和光发酵等发酵制氢过程被认为比其他生物方法(如生物光解)更具可持续性和经济性。然而,这些方法存在诸如氢气产率和转化效率低等限制,因此仍需进行实际应用。本综述评估了利用各种木质纤维素生物质废弃物作为底物,通过暗发酵和光发酵技术生产生物氢的可行性。此外,本综述还包括以生态友好和可持续的方式提高生物氢生产率的策略信息,如暗发酵和光发酵技术的整合、生物质的预处理、微生物的基因改造以及纳米添加剂的应用。
