Genome sequence and description of the mosquitocidal and heavy metal tolerant strain Lysinibacillus sphaericus CBAM5

Abstract

Lysinibacillus sphaericus CBAM5, was isolated from subsurface soil of oil well explorations in the Easter Planes of Colombia. This strain has potential in bioremediation of heavy-metal polluted environments and biological control of Culex quinquefasciatus. According to the phylogenetic analysis of 16S rRNA gene sequences, the strain CBAM5 was assigned to the Lysinibacillus sphaericus taxonomic group 1 that comprises mosquito pathogenic strains. After a combination assembly-integration, alignment and gap-filling steps, we propose a 4,610,292 bp chromosomal scaffold. The whole genome (consisting of 5,146,656 bp long, 60 contigs and 5,209 predicted-coding sequences) revealed strong functional and syntenial similarities to the L. sphaericus C3-41 genome. Mosquitocidal (Mtx), binary (Bin) toxins, cereolysin O, and heavy metal resistance clusters from nik, ars, czc, mnt, ter, cop, cad, and znu operons were identified.
