| Abstract: | A total of 34 yeast isolates were characterized from 4 water samples collected from Kongsfjord at Ny Alseund region of Norwegion Artic during the Indian Artic summer expedition of 2009.They were studied for the effect of tempereture and salt concentration on growth as well as for their ability to produce various hydrolytic enzymes at two different temperatures. Result showed that 5 out of 8 genera were common to all the stations. Cryptococcus was the predominant genera folowed by Trichosporan and Rhodotorula 82% of the yeast isolates were oxidative in nature and except filobasidium all the isolates used nitrate as a nitrogen source for growth. Yeast isolates from all the ststions showed growth at 4 and 20 degree centigarade. These temperatures were chosen as most of the bacterial and yeast isolates showed psychrotrop[hic nature. 94% of the yeast isolates showed growth at 2.0M and lipolytic activity were marginally less than 4.None of the isolates produced amylase enzymes when incubated at 4 and 20. The present study highlights the wide tolerence of the psychrotrophic yeast isolates to temperature and salinity as well as their potential in biotechnology |

| Abstract: | Emergence of antibiotic resistance among aquaculture pathogens has made it necessary to look into environment friendly, effective and sustainable methods such as probiotic and immunostimulants among others.. In the present study, LAB were isolated from the gut of fish species namely Rastrelliger kanagurta and analyzed for their antibacterial activity against various fish, shrimp and human pathogens. Different LAB species such as Lactobacillus plantarum, L. bulgaricus, L. brevis and L. viridiscens were encountered in the gut of R. kanagurta. Several strains showed good activity against fish, shrimp and human pathogens. LAB from the gut of such marine species may be developed as possible probiont for environment friendly health management of fresh water, estuarine and marine species currently exploited in aquaculture |

| Abstract: | Considering the extent of warming in the artic region and the resultant changes in the dynamic marine enviornments there is a need to monitor the bacterial diversity in the fjord enviornments especially in terms of cultivable bacteria. The present study reports the diversity of cultivable hetrotrophic bacteria from the water and sediment samples of kongsfjord their growth responses to important enviornmental variables and ability to produce industrially important hydrolytic enzymes. |
