Many studies have been done on cellulase and several genes encoding for ?-glucosidase have been reported. Here we describe the cloning and sequence analysis of partial putative ?-glucosidase gene from Aspergillus terreus SUK-1. Its potential to produce cellulase enzyme has been studied and reported. A pair of specific primer was designed from the conserved regions of several fungal sequences taken out from the GenBank. PCR amplification has successfully amplified a DNA fragment of approximately 233 bp and this fragment was cloned (designated as SA3). The sequence analysis with BLAST showed high similarity towards ?-glucosidase gene and protein. 80% and 79% homology were observed between SA3 nucleotide sequence and ?-glucosidase gene of A. niger and both A. kawachii and A. aculeatus. Whereas, amino acid sequence of SA3 showed 83% homology towards ?-glucosidase of A. niger, A. kawachii and A. aculeatus.} }
