Sukinda valley of Jajpur district in Odisha is one of the most important chromite hubs of India. The water logged places of this area show the growth of a few numbers of chromium resistant microalgae. Here an experiment was carried out to find out the thermo-tolerant microalgal diversity in the chromium metal polluted sites of Sukinda mining area. Microscopic study and SEM analysis were done for the morphological identification of the algae. Four different thermo- tolerant micro algal strains were identified from the sampling sites of this region among which one green micro alga (Chlorella sp.) and three cyanobacteria (namely Oscillatoria sp., Microcystis sp. and Fischerella sp.) were found. The temperature and hexavalent chromium tolerance properties of these algae were studied taking a temperature range of 25 to 55˚C and Cr (VI) concentration of 10 to 100 PPM. Maximum temperature and Cr (VI) tolerance were observed in Fischerella sp. and Chlorella sp. respectively. Hence, these organisms can be used for the phycoremediation of warm industrial effluents rich in Cr (VI).
