چکیده

A lipase producer psychrophilic microorganism isolated from Arctic sample was studied. The genomic DNA of the isolate was extracted using modified CTAB method. Identification of the isolate by morphological and 16S rRNA sequence analysis revealed that the isolate is closely related to Arthrobacter gangotriensis (97% similarity). A. gangotriensis was determined as positive lipase producer based on the plate screening using specific and sensitive plate assay of Rhodamine B. The PCR result using Arthrobacter sp.'s full lipase gene sequence as the template primers emphasised a possible lipase gene at 900 bp band size. The gene is further cloned in a suitable vector system for expression of lipase.

Draft Genome Sequence of Pseudomonas psychrophila MTCC 12324, Isolated from the Arctic at 79°N

Pseudomonas psychrophila MTCC 12324 is a facultatively psychrophilic bacterium isolated from the Arctic fjord Ny-alesund in the Svalbard Archipelago. Here, we present a 5.2-Mb draft genome sequence of P. psychrophila MTCC 12324, reported for the first time, from the Arctic. This enables a study of the cold adaptation mechanisms to survive under the extreme cold conditions.

Isolation, Optimization, and Molecular Characterization of a Lipase Producing Bacterium from Oil Contaminated Soils

Lipases have many applications in biotechnology, thanks to their ability of acylglycerides hydrolysis. They alsp possess the unique feature of acting at the lipid-water interface, which distinguishes them from esterases. Commercially useful lipases are produced by microorganisms with the extracellular lipase being produced by many bacteria including Pseudomonas. The greatest production of lipas...

Crystal Structure of Proteus mirabilis Lipase, a Novel Lipase from the Proteus/Psychrophilic Subfamily of Lipase Family I.1

Bacterial lipases from family I.1 and I.2 catalyze the hydrolysis of triacylglycerol between 25-45°C and are used extensively as biocatalysts. The lipase from Proteus mirabilis belongs to the Proteus/psychrophilic subfamily of lipase family I.1 and is a promising catalyst for biodiesel production because it can tolerate high amounts of water in the reaction. Here we present the crystal structur...
