Microbiology research will help neutralize the smell of landfills
Scientists at the TSU Biological Institute have launched a research project aimed at creating effective ways to dispose of household and industrial waste. Landfill gases poison lives in the literal and figurative sense. In the summer of 2018, there were reported cases of mass poisoning of people as a result of hydrogen sulfide emissions in urban landfills. The task of microbiologists is to find out exactly which bacteria secrete hydrogen sulfide and find ways to neutralize them.
- The topic of household waste disposal is becoming more acute and is now being offered research funds, -says Olga Karnachuk, project leader, head of the Department of Plant Physiology and Biotechnology at TSU. - Every year in Russia millions of tons of garbage are generated. Spoiled products and waste from pig farms and poultry farms during decomposition form hydrogen sulfide, one of the main components of the unpleasant odor associated with landfills. It is produced by sulfate-reducing bacteria that use sulfate for nutrition.
