equence similarities were determined by the BLAST
program against the database of type strains with validly published prokaryotic names at the EzTaxon 2.1 server
[11]. Molecular Evolutionary Genetics Analysis software
(MEGA version 4.0) [12] was used for phylogenetic analyses.
The sequences of identified phylogenetic neighbours
were aligned with the sequences of representative strains,
using Clustal W inbuilt with MEGA 4. Neighbour-Joining
method was employed to construct the phylogenetic tree
with 1000
