- Water activity is a better index for microbial growth than water content since microorganism only uses available water of the food sample. Some factors affecting the responses of microorganisms to water activity are the production of metabolites, taxonomic classification and solute concentration.
water-filled pore space. Soil respiration was much lower at a bulk density of 1.8 Mg/m. 3 . compared to 1.4 Mg/m. 3, with a 65% reduction of microbial activity at 60% water-filled pore space. This indicates that soil bulk density affects soil microbial activity in ways other than just alteration of soil moisture levels.
