Summary
A mixed population of microorganisms isolated from the municipal garbage compost was cultivated in a full nutrient liquid medium under aerobic conditions. In order to simulate the presence in compost of both noncolloidal and colloidal solid particles, glass beads, bentonite, or humic acid were added to the cultures. The growth of microorganisms and the CO2 evolution rose with bentonite and humic acid, but the humic acid did not enhance the growth of the potential pathogenic bacteria. Solid particles appreciably influenced the endurance to heat stress of microorganisms supporting their adaptation to the changed temperature.
