Impact of Paper Mill Effluent

This book focuses on the impact of paper mill effluent on soil quality, microorganisms and its enzymes involved in the degradation of organic waste matter and nutrient cycling. The microorganisms play a vital role in nutrient cycling and soil fertility. Bacteria and fungi synthesize and secrete enzymes such as starch hydrolyzing bacteria, nitrifying bacteria and phosphate solubilising bacteria. Those microbial secreted enzymes constitute an important part of soil matrix as extracellular enzymes. Thus, there is a considerable interest in the study of enzyme activities of soil which may reflect the potential capacity of the soil to form certain biological transformation of importance to soil fertility.
