Abstract
A bacterium producing novel lipolytic enzyme was isolated from house sewage and identified as Acinetobacter sp. BD5 based on physiological characterization and 16S rDNA sequencing. The lipolytic activity of Acinetobacter sp. BD5 was tested using an EL agar medium and CE agar medium supplemented with 1% tributyrin and olive oil, respectively. The formation of a clear zone around the colony was detected by agar medium supplemented with 1% tributyrin and olive oil, respectively and Acinetobacter sp. BD5 formed powder-like zone around the colony on LB agar medium containing Tween 20. The quantitative lipolytic activity was determined by using p-NP butyrate as substrate. Acinetobacter sp. BD5 secreted the lipolytic enzyme during exponential growth phase, reaching a maximum amount after 6 hours of incubation. The lipolytic enzyme was found to be optimally active at $60^{\circ}C$ and retained more than 70% at $70-80^{\circ}C$. It displayed a high degree of activity in a pH of 7.0 to 10.6, with an optimal pH of 9.0.
