[Impact of sewage sludge composting conditions on colibacillus growth].
An exothermic reaction that takes place during organic residue composting causes the death of pathogenic microorganisms, protozoa, and helminth eggs. However, the bacteria of the colibacillus group can preserve vital activities under such conditions. Sewage sludge fermentation gives off not only heat, but also moisture that, by lowering the temperature of composted mass, serves as a factor contributing the propagation of these microorganisms. Close observance of composting technology prevents the development of colibacilli.
