Draft Genome Sequence of a Moderately Halophilic Bacillus megaterium Strain, MSP20.1, Isolated from a Saltern of the Little Rann of Kutch, India

Abstract

The 4.37-Mbp draft genome of a moderately halophilic Bacillus megaterium strain, MSP20.1, isolated from a saltern of the Little Rann of Kutch, India, is reported here. To understand the mechanism(s) of moderate halophilism and to isolate the gene(s) involved in osmotolerance and adaptation, the genome of MSP20.1 was sequenced.

Study of Bacillus megaterium potential application for high metal content residues biotreatment

“…It has been previously reported that Bacillus megaterium possesses high levels of resistance to hostile conditions [7,8], including the exposition to metals like Hg and Ni [9,10], and some B. megaterium strains also present the demonstrated ability to remove metals from solid and liquid residues [10][11][12], establishing their potential to treat phosphogypsum waste [13], and spent catalysts [14,15]. Specifi cally, B. megaterium strain MNSH1-9K-1 presents the ability to resist up to 200 ppm of each Ni and V contained in a liquid mixture, being able to remove up to 15.38 ± 1.30 ppm of Ni contained in the former liquid medium [12].…”

Expression Analysis of Ni- and V-Associated Resistance Genes in a Bacillus megaterium Strain Isolated from a Mining Site

“…It is a common model organism for a variety of cellular processes including morphology, replication, and sporulation, and it is used in industrial applications for production of recombinant proteins [11] and vitamin B12 [6,18,32]. Recently, B. megaterium has been characterized for an intrinsically high level of resistance to hostile conditions including 20 % of salinity [21,28] and metal exposition (e.g., mercury and nickel) [20,26]. Because of this capacity, B. megaterium has been used in the biological treatment of wastes with high metal content like nickel, vanadium, rhenium, and platinum [6,14,21].…”

Because of this capacity, B. megaterium has been used in the biological treatment of wastes with high metal content like nickel, vanadium, rhenium, and platinum [6,14,21]. Particularly, nickel is considered a hazardous metal which is part of several industrial wastes, including those from petrochemical process, thus creating serious problems in terms of environmental pollution due to their accumulation [1].…”
