Massive discharge of wastes produced by the processing of leather so far confers the most important environmental challenge facing the tanneries worldwide. Waste material from tanneries mostly consists of skin remnants and proteinaceous substances as by-products of leather processing. In these conditions, protease-producing bacteria play a vital role in degrading wastes in this sludge. Therefore, an investigation was made to study the effect of long-term tannery sludge contamination on the diversity of both protease-producing microbes and of bacterial extra
