dc.description.abstractThe study showed that a significant fraction of coliform bacteria survive for more than six months in soil at different temperatures and moisture contents. Survivability of coliform bacteria at subzero temperatures decreased with an increase in moisture content and with an increase in temperature. Total coliform bacteria in soil samples placed outdoors during winter had lower survivability in comparison to samples placed at controlled temperatures below O⁰c. High survivability of total coliform bacteria at controlled, subzero temperatures was assumed to be related to the reduced metabolic activities of the bacteria.en_US
