In the present study, psychrophilic yeasts, which grow on lactose as a sole carbon source at low temperature and under acidic conditions, were isolated from soil from Hokkaido, Japan. The phenotypes and sequences of 28S rDNA of the isolated strains indicated a taxonomic affiliation to Guehomyces pullulans. The isolated strains were able to grow on lactose at below 5 degrees C, and showed cold-active acid beta-galactosidase activity even at 0 degrees C and pH 4.0 in the extracellular fractions… CONTINUE READING
