Abstract

Sulfurifustis variabilis and Sulfuricaulis limicola are autotrophic sulfur-oxidizing bacteria belonging to the family Acidiferrobacteraceae in the order Acidiferrobacterales. The type strains of these species, strain skN76T and strain HA5T, were isolated from lakes in Japan. Here we describe the complete genome sequences of Sulfurifustis variabilis skN76T and Sulfuricaulis limicola HA5T. The genome of Sulfurifustis variabilis skN76T consists of one circular chromosome with size of 4.0 Mbp including 3864 protein-coding sequences. The genome of Sulfuricaulis limicola HA5T is 2.9 Mbp chromosome with 2763 protein-coding sequences. In both genomes, 46 transfer RNA-coding genes and one ribosomal RNA operon were identified. In the genomes, redundancies of the genes involved in sulfur oxidation and inorganic carbon fixation pathways were observed. This is the first report to show the complete genome sequences of bacteria belonging to the order Acidiferrobacterales in the class Gammaproteobacteria.

Genome project history Sulfurifustis variabillis skN76T and Sulfuricaulis limicola HA5T were selected for sequencing as representatives of sulfur-oxidizing bacteria belonging to the order Acidiferrobacterales, to reveal characteristics of their genomes

Summary

Introduction

Sulfurifustis variabilis skN76T and Sulfuricaulis limicola HA5T are gammaproteobacterial sulfur-oxidizing bacteria isolated from sediments of Lake Mizugaki and Lake Harutori, respectively [1, 2]. Introduction Sulfurifustis variabilis skN76T and Sulfuricaulis limicola HA5T are gammaproteobacterial sulfur-oxidizing bacteria isolated from sediments of Lake Mizugaki and Lake Harutori, respectively [1, 2]. We show the complete genome sequences of Sulfurifustis variabilis skN76T and Sulfuricaulis limicola HA5T as the first genomes of the order Acidiferrobacterales.
