The fermentative production of H2 from residual glycerol is an attractive alternative for clean energy production from a waste product. Selection of operational variables for microbial populations with an adequate diversity in order to improve H2 yields is an issue faced during optimization of biological production of H2. Operational and environmental factors affect both microbial diversity and the activity of specific enzymes. Therefore, these variables must be controlled to obtain the best H2 yields. This review covers the main variables involved in the fermentative production of H2 from crude glycerol and the biochemistry of the anaerobic digestion of glycerol, with a focus on the microbial diversity involved in this process.
利用残余甘油发酵生产氢气是从废弃物中生产清洁能源的一种有吸引力的替代方法。为了提高氢气产量，在优化生物制氢过程中，选择具有足够多样性的微生物群体的操作变量是一个面临的问题。操作和环境因素会影响微生物多样性以及特定酶的活性。因此，必须控制这些变量以获得最佳的氢气产量。本综述涵盖了从粗甘油发酵生产氢气所涉及的主要变量以及甘油厌氧消化的生物化学，重点关注该过程中涉及的微生物多样性。
