Genomic insights into Brevibacterium sediminis strain IMA_C3 isolated from an integrated mangrove aquaculture pond
Abstract
Abstract Brevibacterium sediminis strain IMA_C3, a Gram-positive bacterium, was isolated from an integrated mangrove aquaculture pond near the Sundarbans mangrove. The bacterium was isolated from mangrove leaf litter and grown on Luria-Bertani medium at a salinity of 20. Phylogenetic analysis based on 16S rRNA sequencing showed a 99.67% identity with Brevibacterium linens AE038-8 from the International Nucleotide Sequence Database Collaboration DNA databases (GenBank/DDBJ/ENA). Whole-genome sequencing was carried out using long-read sequencing on the Oxford Nanopore MinION platform, with genome annotation performed against the NCBI Reference Sequence Database and The Genome Taxonomy Database databases. The genome is ~4.1 Mb in size, with a G+C content of 64.59 mol%. Functional analysis of the genome revealed genes related to complex carbon utilization, nitrogen and phosphate metabolism and metal transport. Additionally, the genome encodes secondary metabolites, including ε-poly-l-lysine, ectoine, terpene and phenazine, which could have potential applications in controlling viral infections in indigenous shrimp populations within integrated mangrove aquaculture systems.
