Abstract
In this research, extremely halotolerant hydrogen-producing bacteria from slat damaged soil ini Thailand were investigated, by utilizing the in dark fermentation process to produce bihydrogen from sugars acquired from waste sources, these extremophilic bacteria can oofer the advantage of cost cutting for fresh water, oxygen and sterilization in the development oh ‘ Next Generation Industrial Biotechnology’. The biohydrogen production experiments at 3-10% and 15-26% NaCI were conducted. A comparison study was made before and after acclimatization period of 2 years. During the acclimatization period, the substrate for the bacteria was kept at 26% NaCI condition. The result showed that before the acclimatization period, the highest production of 2.78 mol H2/mol glucose occurred at 15% salinity, with no hydrogen production observed at 26%, with hydrogen yields of 0.66-1.15 mol h2/mol glucose, this indicates that extremely halotolerant hydrogen-producing bacteria can exist under high salt concentrations. Further studies will be made to investigate the microbial community characteristics and their applications for hydrogen production from lignocellulosic biomass.
