Research on cellulase has progressed very rapidly over the last five decades. Now a day, majority of commercial cellulases are being produced by fungi such as, Trichoderma. However halophilic fungi can be a valuable resource for the same. The present study deals with the extracellular cellulases from Halophilic fungi isolated from the Great Rann of Kutch, India. The isolates, designated as B10-1 and D10-2 were having mycelia structure similar to Aspergillus spp. and grew optimally with 10% w/v NaCl. B10-1 and D10-2 grew optimally at pH 6 with slow growth at higher pH. In case of B10-1 and D10-2, the optimum cellulose concentration for cellulase production was 0.5% w/v and 1.5% w/v respectively. Both the isolates produced cellulase optimally at 10% NaCl and pH 6. B10-1 and D10-2 exoglucanase were purified to 10.98 fold and 4.23 fold respectively by (NH4)2SO4 fractionation. Partially purified extracellular exoglucanase was characterized further. The enzymes displayed optimum activity at...
