According to the thermodynamical prognosis developed by us the investigation of the interaction of Bacillus-Clostridium community and six representative metals was performed. To representative metals we refer: oxidisers (CrO42-), substitutes (Ni2+, Co2+) and combined action metals that combine the characteristics of both oxidizers and substitutes (Cu2+, Hg2+, Fe3+). The natural soil hydrogen-producing microbial communities appeared to be resistant to the metals in their high total concentration of 120 mg/l and also able to extract these metals from the solution (up to 96%).The obtained regularities are the base for the development of new combined biotechnologies, allowing to neutralize ecologically hazardous food wastes, treat metal contaminated sewages and simultaneously obtain environmentally friendly energy source – hydrogen.
