POTENTIAL OF BACTERIA AS FAT BIODEGRADATION IN THE DOMESTIC WASTE POLLUTED ENVIRONMENT

Contamination of fat waste into the aquatic environment originating from industrial food processing, restaurants and kitchens or by accidental oil spills is now increasingly found. Biodegradation using a bacterial consortium can be an effective way to overcome this. The main objective of this research is to isolate and identify strains of bacteria from fat waste that is capable of biodegradation of domestic fat waste. Samples were taken from the BTDC sewage sediment processing waste, Indonesia Power waste management, Badung River estuary dam and restaurant waste storage in several hotels in Nusa Dua Bali. Enrichment techniques were followed in all samples followed by isolation of bacterial strains to determine which strains could reduce fat in vitro. Some morphology for bacterial strains was carried out to determine bacterial characteristics and continued identification using the BBL Crystal System Identification kit. It is expected that from this research found fat degrading bacteria which will be used as a strarter for processing organic fat waste.
