Identification sporeforming bacteria in associations of hydrogen-generating microorganisms

Abstract

The purpose. To determine species composition of spore-forming bacteria of associations of hydrogen-generating microorganisms for assessment of an opportunity of their biotechnological application. Methods. Phonotypical and phylogenetic analysis, chemical­alytical, gas chromatography. Results. Bacillus and Clostridium predominate in structure of an probed associations. Under morphological, cultural-biochemical and molecular-genetic characteristics they identified 3 strains to species. The strain of anaerobic bacteria is identified as Clostridium butyricum VU-11. strains of aerobic bacteria - as Bacillus licheniformis BS-3 and Bacillus atrophaeus BS-1. Conclusions. Bacillic-clostridial associations are perspective for cost effective synthesis or power supply H2 from a wide spectrum of renewable biomass, including food waste.
