摘要

Proteinaceous material constitute the main source of nitrogen in soil organic matter. Use of this nitrogen is limited by the breakdown of proteins into peptides and free amino acids. Proteases, therefore, are important in the use of protein N. The aim of this study is to assess the effect of subtilisin, which is a soil extracellular endopeptidase from Bacillus sp., both on soil microbial biostimulation and biodiversity. In addition to the protease, keratins, an insoluble-protein and low-bioavailable substrate, was added to enhance the effect of protease in soil. Protease, both on its own and in combination with keratins, has a biostimulant effect on soil microbial activity that was reflected in the protease, dehydrogenase and phosphatase activities.
