To date, the genus Mangrovimonas consists of only one species, Mangrovimonas yunxiaonensis strain LY01 that is known to have algicidal effects against harmful algal blooms (HABs) of Alexandrium tamarense. In this study, the whole genome sequence of three Mangrovimonas-like strains, TPBH4T(=LMG 28913T,=JCM 30882T), ST2L12T(=LMG 28914T,=JCM 30880T) and ST2L15T(=LMG 28915T,=JCM 30881T) isolated from estuarine mangrove sediments in Perak, Malaysia were described. The sequenced genomes had a range of assembly size ranging from 3.56Mb to 4.15Mb which are significantly larger than that of M. yunxiaonensis LY01 (2.67Mb). Xylan, xylose, L-arabinan and L-arabinose utilization genes were found in the genome sequences of the three Mangrovimonas-like strains described in this study. In contrast, these carbohydrate metabolism genes were not found in the genome sequence of LY01. In addition, TPBH4T and ST2L12T show capability to degrade xylan using qualitative plate assay method.
