Carboxymethyl Cellulose Hydrolyzing Yeast Isolated from South East Sulawesi, Indonesia
ABSTRACT: The objective of
study was to isolate, identify and characterize the CMC-ase producing yeast
from South East Sulawesi, Indonesia. We isolated 142 strains and obtain 53
strains (37.32%) were CMC-ase producer consist of 26 species residing within 10
genera. Candida was the most diverse genus consisting of 15 species. It is important
to note that several strains residing within this genus could be candidate for
new taxa, among others Candida aff. cylindracea PL2W1, Candida aff. insectorum
PL3W6, Candida aff. friedrichii MKL7W3, Candida aff. lessepsii, Candida aff.
tenuis. Five new candidates for novel species of cellulolytic yeast close to Yamadazyma
mexicana: were Yamadazyma aff. mexicana (5 strains). Pichia, Pseudozyma,
Sporodiobolus, and Sporobolomyces were other cellulolytic yeasts found in South
East Sulawesi. It is obvious, that leaf litter was agood source for
cellulolytic yeasts. This CMC-ase producing yeasts dominate this biome, and
production of extracellular cellulase is critical strategy for such yeast to
survive in cellulose rich ecosystem such as leaf-litter. This finding would
suggest that yeasts play key role on hydrolyzes of cellulose and important
resources for sustainable energy research.
