dc.description.abstractWe have investigated the biotechnological potential of Arctic marine bacteria for their ability to produce a broad spectrum of cold-active enzymes. Marine bacteria exhibiting these features are of great interest for both fundamental research and industrial applications. Macrobiota water and sediment samples have been collected during 2010 and 2011expeditions around the Lofoten and Svalbard islands. Bacteria were isolated from this material and identified through 16S rRNA gene sequence analysis for the purpose of establishing a culture collection of marine Arctic bacteria. <p>Herein, we present the functional screening for different extracellular enzymatic activities from 100 diversely chosen microbial isolates incubated at 4 and 20°C. The production of esterase/lipase, DNase and protease activities were revealed in 67%, 53% and 56% of the strains respectively, while 41%, 23%, 9% and 7% of the strains possessed amylase, chitinase, cellulase and xylanase activities, respectively. Our findings show that phylogenetically diverse bacteria, including many new species, could be cultured from the marine arctic environment. The Arctic polar environment is still an untapped reservoir of biodiversity for bioprospecting.en_US
