From 40 isolates tested, 10 isolates showed lipolytic activity on agar plate media containing olive oil and rhodamine B. The isolates showed lipolytic activity in the range of 15 – 315 U/L on p-nitrophenyl palmitate (pNPP) as substrate. Two isolates, namely PI6A and PI13C, were further characterized and showed maximum specific activity at a mid exponential of growth phase. Identification of the isolate was performed through ribotyping method. Chromosomal DNA from these isolates was extracted and the 16S rRNA gene fragments were amplified, resulting fragment length at around 1.5 kb on agarose gel. Further analysis of the 16S rRNA gene sequences using homological and phylogentetical methods showed that the PI6A and PI13C were close to Bacillus licheniformic and Bacillus subtilis respectively.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]16S rRNA,Compost,Lipase,Pasir Impun,Thermophiles[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
