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.
