Biohydrogen productions from hydrolysate of water hyacinth stem (Eichhornia crassipes) using anaerobic mixed cultures

Response surface methodology (RSM) with central composite design (CCD) was applied to optimize key factors affecting hydrogen production (HP) from diluted acid hydrolysate of water-hyacinth stem (WHS) by heat-treated anaerobic sludge in a batch fermentation process. Key factors affecting namely subs...
