Abstract
L Glutaminase and L- methioninase, therapeutic enzyme obtained from microbial source have been considered in the treatment of cancer. A total 20 water samples were obtained from the Yale Gonbad hot spring in Qazvin province, Iran. Production capabilities L Glutaminase and L- methioninase were tested on m9 and mcd plates, respectively. Enzyme-producing isolates were identified by conventional test and then confirmed using molecular methods. The PCR amplicons were directed for sequencing and Phylogenetic tree were drawn using Mega version 6 software. Twelve colonies were obtained from all tested samples. Three extratermophilic isolates showed L-glutaminase activity in M9 medium but only 1 isolates have L-methioninase activity in MCD medium. The phylogenetic tree drawn from the 16 S rRNA gene sequence showed were 100% similar to B. licheniformis and strains of S. epidermidis and L. sphaericus. In this study, Bacillus licheniformis was identified as a dominant and a native strain for the production of L-glutaminase and L-methioninase.
