Bacterial lipases are the most important collection of biocatalysts used for a variety of biotechnological applications. In the current study the morphological, biochemical and Molecular characteristics to the extracellular lipase producing bacteria were identified. The bacterial isolates were selected as lipase producing bacteria using Rhodamine-B agar plate. the production of Lipase from the organism were determined with varying incubation temperature (20 to 50°C) and range of incubation time (16-120) hrs. 16 bacterial isolates were identified as Staphylococcus hemolyticus strain SHKS1 with Genbank acc. MK977614.1. By comparing the observed DNA sequences of these local samples with the retrieved DNA sequences (GenBank acc. MG595372.1) as showed high lipase activity according to experimental conditions about 140 U/ml. The current study showed that enzymatic activity of crude lipase extract was maximum in 72 hrs incubation period and 37°C.
