This study produced biohydrogen from maize straws by an enriched consortium via photo-fermentation pathway. The maize straws can be utilized by the consortium as substrate only after micro-grinding and enzyme hydrolysis pretreatments. Batch tests at 30?g/L maize straw, pH 7.0, 30?¢XC, illumination intensity 2000?lx yielded 9.33?mol H2/mol glucose with illumination energy conversion rate of 13.7% and substrate-energy conversion rate of 5.3%. Equivalently, the biohydrogen productivity is about 3?mmol/g maize straw. Reaction temperature can affect hydrogen production rate but only minimally affect the delayed time. The activation energy for biohydrogen production was estimated to be 5.65?kJ/mol. ? 2016 Hydrogen Energy Publications LLCEnzyme hydrolysisHydrogen productionMicro-grindingStrawsTemperature[SDGs]SDG7Activation energy; Bacteria; Energy conversion; Enzymes; Grinding (machining); Hydrolysis; Straw; Substrates; Temperature; Bio-hydrogen production; Energy conversion rates; Enzyme hydrolysis; Hydrogen production rate; Illumination intensity; Micro-grinding; Photosynthetic bacterias; Photosynthetic hydrogen productions; Hydrogen productionjournal article10.1016/j.ijhydene.2016.07.0292-s2.0-84978828531https://www.scopus.com/inward/record.uri?eid=2-s2.0-84978828531&doi=10.1016%2fj.ijhydene.2016.07.029&partnerID=40&md5=b324e380b6ad1ba41f5675f2d343658d
