In this work, a strain named YPW1 was isolated from the sediments of an artificial mangrove in Yanpu harbor, China. A complete genome of YPW1 was sequenced and assembled. The 16S rRNA gene assigned strain YPW1 into genus Microbulbifer, and the maximum values of average nucleotide identity and digital DNA–DNA hybridization of ZHDP1 genome were 90.36 and 68.1, respectively, indicating that YPW1 was a potential new species in genus Microbulbifer. A total of 10 representative genomes from genus Microbulbifer were selected to compare with YPW1. The results showed that the genome of strain YPW1 possessed more carbohydrate-active enzyme genes to transform various recalcitrant polysaccharides into bioavailable monosaccharides than those of the selected genomes. Furthermore, among the selected genomes, YPW1 was the only strain with nitrate, nitrite, and nitric oxide reductases which could appoint nitrous oxide, a powerful greenhouse gas, as the end-product of its denitrification process. Therefore, strain YPW1 was a potential novel member of genus Microbulbifer with special ecological roles in the cycles of carbon and nitrogen in mangrove ecosystems.

In this study, the complete mitogenome of Lysmata vittata (Crustacea: Decapoda: Hippolytidae) has been determined. The genome sequence was 22003 base pairs (bp) and it included thirteen protein-coding genes (PCGs), twenty-two transfer RNA genes (tRNAs), two ribosomal RNA genes (rRNAs) and three putative control regions (CRs). The nucleotide composition of AT was 71.50%, with a slightly negative AT skewness (−0.04). Usually the standard start codon of the PCGs was ATN, while cox1, nad4L and cox3 began with TTG, TTG and GTG. The canonical termination codon was TAA, while nad5 and nad4 ended with incomplete stop codon T, and cox1 ended with TAG. We compared the order of genes of Decapoda ancestor and found that the positions of the two tRNAs genes (trnA and trnR) of the L. vittata were translocated. The phylogenetic tree showed that L. vittata was an independent clade, namely Hippolytidae.

In this work, a strain named YPW1 was isolated from the sediments of an artificial mangrove in Yanpu harbor, China. Whole genomic sequencing was conducted to reveal the potential ecological roles of strain YPW1 for the environment. The result of 16S rRNA gene alignment assigned strain YPW1 into Microbulbifer genus, and then, 10 representative genomes from Microbulbifer genus were selected to compare with YPW1. Results showed that the genome of strain YPW1 possessed more carbohydrate-active enzyme genes to transform various recalcitrant polysaccharides into bioavailable monosaccharides than those of the selected genomes. Furthermore, among the selected genomes, YPW1 was the only strain with nitrate, nitrite, and nitric oxide reductases which could appoint nitrous oxide, a powerful greenhouse gas, as the end-product of its denitrification process. Therefore, strain YPW1 was a member of Microbulbifer genus with special ecological roles that served as the center for the degradation and utilization of polysaccharides and the performer of denitrification with greenhouse gas as the end-product, and the abundance and biological activity of YPW1 could be an indicator to reflect the ecological function of this artificial mangrove in energy material providing and climate regulation.
