Efficiency of newly isolated proteolytic, lipolytic and amylolytic bacterial isolates on degradation of different agro-wastes

Abstract

Three bacterial strains with proteolytic, lipolytic and amylolytic activities were tested for their efficiency in enhancing the biodegradation of different organic wastes. The organic material was inoculated initially with fungal inoculant (5.0 g/kg). Bacterial consortia (1% v/w) were added after thermophilic phase and composting was carried out for 100 days. The samples drawn regularly and analyzed for organic carbon, total nitrogen, humus content and available P. The results showed that bacterial consortia inoculation enhanced the decomposition of different residues and reduced the composting time by 20–30 days.
