The soils in good physical condition have better aeration and moisture content which is essential for optimum microbial activity. With increase in bulk density, the volume of pores decreases and vice versa . Soil 1 6. in agriculture are either degraded by the soil organisms or are liable to leave toxic residues in soil which are hazardous to cause profound reduction in the  normal microbial activity in the soil. Most of the soil microorganisms are mesophilic (25 to 40 °) and optimum temperature for most mesophiles is 37° C. True psychrophiles are almost absent in soil, and thermopiles though present in soil behaves like mesophiles. Factors Affecting the Bulk Density of Inorganic Soils: As moisture increases, respiration rates increase until the pores are overly saturated, resulting in lower oxygen content and lower soil organism respiration. Stnt-LIIS. - The global yeast extract market is anticipated to be valued at US$ 1.1 Bn in 2019. Soil temperature: Next to moisture, temperature is the most important environmental factor influencing the biological physical & chemical processes and of microbes, microbial activity and population in soil. While in the absence of adequate moisture in soil, some of microbes die out due to tissue dehydration and some of them change their forms into resting stages spores or cysts and tide over adverse conditions. The soil bacterial community is under the constant influence of its environment. Most studies in soil microbiology have been concerned with either specific groups of the soil microflora or specific activities such as nitrifi- cation, organic matter transformations, or repression of plant pathogens.
