Abstract
Biodegradation of toxic organic contaminants has been documented to involve a large number of bacterial, fungal, and plant microbial enzymes. Biodegradation is a cost-effective biotechnology powered by microbial enzymes. This chapter intends to provide detailed information on the application of microbial enzymes in the bioremediation of heavily polluted environment. Detailed information on the application of microbial enzymes and their modes of action were also provided in detail. Various types of microbial enzymes were also provided in detail. Specific information on high-rate up-flow anaerobic bed reactor and digester wastewater effluents were also highlighted while the process involved in the degradation efficiency in soil washing effluence by polycyclic aromatic hydrocarbons were stated. Techniques involved in the removal of phenanthrene, fluoranthene, and pyrene in soil washing effluent, the immobilization of specific microorganism and their enzymes with a cross-linking system when investigated using polyvinyl alcohol, sodium alginate, and nano alumina composites.
