Genomic analysis of a functional haloacid-degrading gene of Bacillus megaterium strain BHS1 isolated from Blue Lake (Mavi Gölü, Türkiye)
Purpose: Bacillus megaterium strain BHS1, isolated from an alkaline water sample taken from Mavi Gölü (Blue Lake, Türkiye), can grow on minimal medium containing 2,2-dichloropropionic acid. We characterized this bacterium at the genomic level. Methods: The HiSeq platform was used to carry out genome...
