The physiological researches of each yeasts strain were carried out by using over 5
tests for assimilation of carbon and their catalase activity (Table 6 & 7). The utilization of
four polysaccharides namely carboxy methyl cellulose (CMC), starch, xylan and pectin was
tested. All the strains isolated were found to assimilate the named polysaccharides and
produce detectable amount of extra cellular cellulase, amylase, xylanase and pectinase
respectively. Moreover, the strains also exhibited catalase ability of various degrees.
