An aerobic pure culture (18) was isolated from the tablet of mixed culture bacteria which is originated from a farm land. The gram positive isolate able to degrade phenol about 550 mg/l.d. Morphology of the isolate changes with the culture ages. it was in rod shape during the logarithmic growth phase and changes to the o valform during the stationary phase. The range of temprature growth is 27-34C and the optimum temprature of the isolate is 30C with doubling time about 7 hours. Substrate could be utilized by the isolate are alcohol, aromatic compound and carbohydrate. Methanol, ethanol, isopropanol (each 10%; v/v), 4-Chlor phenol (0.2 mM), 4-nitrophenol(0.25 mM), anniline (1 mM) and glucose are some substrate has been tested for the bacterial growing. Salt (NaCl) tolerance for the isolate is up to 2% (v/v) and the addition of ammonium salt would be support the bacterial growthKey words:Bacterial tablet, aerobic, phenol degradation, 4-chlor phenol, 4-nitro phenol, anniline, glucose, methanol, ethanol, iso-propanol, isolation, partial characterization.

Biodegradation test of aromatic compounds by pure cultureof bacterial isolate I4 from bacterial tablet using mineral mediumas growth medium was done. Aromatic compounds tested ascarbon sources used were phenol, p-chlorphenol, p-nitrophenol,2,4 dichlorphenol and benzene. The oval colony forming and highmotility isolate is an aerobic and gram negatif bacteria. Theisolate was able to use citric acid as carbon source, producedacid .from methyl red test and gave negative result of indol test.The isolate formed a slightly blue-green colour colony on agarslant, and it did not use ethanol as carbon source. Thecharacteristic of the isolate I4 indicated that it belonged to thegenus Pseudomonas. Test using selective media confirmed thatthe isolate I4 is a Pseudomonas fluorescence. The capability ofthe bacteria to oxidize of 2,4 dichlorphenol was relatively fast.Experimental results showed that the bacteri grew on benzene atconcentration of 10% (v/v), and degraded 2,4 dichlophenol withrelatively high rate.Keywords: Bacterial tablet, aromatic compounds, phenol. pchlorphenol,2,4 dichlorphenol, p-nitrophenol, benzene, pure culture,Pseudomonas fluorescence, isolate I4

Municipal solid waste is still a big problem in the cities of Indonesia especially in the Capital and capital of province. Open dumping in TPA is operated through all of Indonesian cities, this bring to consequences a bad influence to the environment. Conversion of Organic solid waste either to energy or biofertilizer is one of the best choices on the solid waste management. These methods will create a good manageable of cities environment, producing fertilizer for the farmer, energy for the communal and jobs for the people. Municipal organic wastes were grinded andfermented in anaerobic aerobic conditions. Anaerobic conditions produce rrydrogen or methane as bioenergy meanwhile aerobic fermentation was used to get either compost or liquid oiofertilizer. The result of Bioenergy and biofertilizer production showed that Municipal organic waste has a great potential as substrate for bioenergy such as hydrogen and methane or substrate for biofertilizer. The biofertilizer could be either as compost or liquid biofertilizer which are rich with growth promoting substances produces by specific bacteria during municipal organic solid waste fermentation.Key words: Municipal, organic solid waste, management, bioenergy, bioJertilizer
