Abstract

Species of the genus Halomonas are halophilic and their flexible adaption to changes of salinity and temperature brings considerable potential biotechnology applications, such as degradation of organic pollutants and enzyme production. The type strain Halomonas lutea YIM 91125T was isolated from a hypersaline lake in China. The genome of strain YIM 91125T becomes the twelfth species sequenced in Halomonas, and the thirteenth species sequenced in Halomonadaceae. We described the features of H. lutea YIM 91125T, together with the high quality draft genome sequence and annotation of its type strain. The 4,533,090 bp long genome of strain YIM 91125T with its 4,284 protein-coding and 84 RNA genes is a part of Genomic Encyclopedia of Type Strains, Phase I: the one thousand microbial genomes (KMG-I) project. From the viewpoint of comparative genomics, H. lutea has a larger genome size and more specific genes, which indicated acquisition of function bringing better adaption to its environment. DDH analysis demonstrated that H. lutea is a distinctive species, and halophilic features and nitrogen metabolism related genes were discovered in its genome.

Highlights

We present a summary classification and a set of features for H. lutea strain YIM 91125T, together with the description of the genomic sequencing and annotation, and provide brief findings of its genome sequence as compared to genomes of other Halomonas species
Strain YIM 91125T (= DSM 23508T = KCTC 12847T = CCTCC AB 206093T) is the type strain of Halomonas lutea [1]
Halomonadaceae comprises the largest number of halophilic and halotolerant bacteria described to date, and Halomonas is the largest genus in this family

Summary

Introduction

We present a summary classification and a set of features for H. lutea strain YIM 91125T, together with the description of the genomic sequencing and annotation, and provide brief findings of its genome sequence as compared to genomes of other Halomonas species. The comprehensive genomes of this genus will facilitate our understanding of the ecological roles that Halomonas species play in those hypersaline habitats and their relationships with other halophilic and nonhalophilic microorganisms.
