Hydrogen-producing granules with an excellent settling ability were cultivated in an upflow anaerobic sludge blanket reactor treating a sucrose-rich synthetic wastewater. The physicochemical characteristics of granules were evaluated in this study. The mature granules had a diameter ranging from 1.0

The experiment was conducted to evaluate the performance of an upflow anaerobic sludge blanket (UASB) with granules for H 2 production from a sucroserich synthetic wastewater at various substrate concentrations (5.33-28.07 g-COD/L) and hydraulic retention times (HRTs) (3-30 h) for over 3 years. The
## Abstract A novel approach to rapidly initiate granulation of hydrogenβproducing sludge was developed in an anaerobic continuous stirred tank reactor at 37Β°C. To induce microbial granulation, the acclimated culture was subject to an acid incubation for 24 h by shifting the culture pH from 5.5 to
