Genome description of a potentially novel species of Brevibacterium sp. strain IMA_C3 isolated from an integrated mangrove aquaculture pond

Brevibacterium sp. strain IMA_C3, a Gram-positive bacterium, was isolated from an integrated mangrove aquaculture pond in close proximity to Sundarbans mangrove. The bacterium was isolated from mangrove leaf litter and grown on Luria-Bertani medium with salinity of 20. The 16S rRNA sequence of this isolateshowed 99.67% identity with Brevibacterium linens AE038-8 from the INSDC DNA databases (GenBank/DDBJ/ENA). Whole-genome sequencing was carried out using long-read sequencing using Oxford Nanopore Technologies chemistry in MinION platform, followed by genome annotation undertaken against the RefSeq and GTDB databases. The genome is approximately 4.1 Mb in size, with G+C content of 64.59%. Functional analysis of the draft genome revealed presence of genes related to complex carbon utilization, nitrogen and phosphate metabolism, and metal transport. Additionally, the genome encodes for secondary metabolites, including ε-Poly-L-lysine, ectoine, terpene, and phenazine, that could have potential applications in controlling viral infections in indigenous shrimp populations within integrated mangrove aquaculture systems.
