ABSTRACT:
The invention provides an isolated haloalkaliphilic microorganism designated as strain sapolanicus belonging to the genusHalanaerobium, which is capable of producing hydrogen from biomass. Methods of producing biohydrogen comprising the fermentation of the microorganism with alkaline pretreated biomass are also provided. Fermentation is preferably carried out without neutralization of the pretreated biomass and at a pH of greater than or equal to about 10.
