Screening of lipolytic bacteria from domestic compost resulting an isolate namely AL17. Morphological analysis shows that the isolates were rod shape and belong to negative gram bacteria. The 16S rRNAs genes of the bacteria have been sequenced, and phylogenetic analysis showed that the isolates were close to genus Pseudoxanthomonas. The enzyme production was synchronized with bacterial growth and reached a maximum level during the late-stationary phase. The optimum pH and temperature of enzyme activity were at pH 9.0 and 60°C.The isolate also showed alcohol tolerance in medium containing 3% and 5% methanol. The ability of bacterial cells to tolerate methanol is an important cell characteristic that determines their use as a biocatalyst in transesterification and other industrial process.
