The phylogenetic shift in the HCH-dumpsite exhibited a relatively higher abundance of genes coding for chemotaxis/motility, chloroaromatic and HCH degradation (lin genes), which provides evidence for the horizontal transfer of HCH catabolism genes.
Novosphingobium panipatense sp. nov. and Novosphingobium mathurense sp. nov., from oil-contaminated soil.
Results indicate that strains SM16T and SM117T belong to separate species of the genus Novosphingobium, for which the names Novosphersobium panipatense sp.

Evolution of mercuric reductase (merA) gene: A case of horizontal gene transfer
The close association among members of different groups in merA gene tree, as supported by high bootstrap values, deviations in GC content and codon usage pattern indicate the possibility that horizontal gene transfer events might have taken place during the evolution of this gene.
Flavobacterium ummariense sp. nov., isolated from hexachlorocyclohexane-contaminated soil, and emended description of Flavobacterium ceti Vela et al. 2007.
Phylogenetic inference and phenotypic properties indicated that strain DS-12(T) represents a novel species of the genus Flavobacteria, for which the name Flavobacterium ummariense sp.
