Molecular identification of Staphylococcus xylosus MAK2, a new α-l-rhamnosidase producer

A bacterial strain, MAK-2, was isolated as a producer of α-l-rhamnosidase from a soil sample of Dehradoon, India. The strain was identified based on morphology, physiological tests and 16S rDNA analysis. The phylogenetic analysis based on the 16S rDNA sequence, identified the isolate as Staphylococcus xylosus, a nonpathogenic member of CNS (coagulase-negative staphylococci) family. The strain was capable of producing α-l-rhamnosidase by hydrolysing flavonoids thus confirming potential application in the citrus-processing industry.
