Abstract
Here we report the draft genome sequence of strain Q-1, an iodide (I−)-oxidizing heterotrophic bacterium in the class Alphaproteobacteria isolated from natural gas brine water. The genome sequence contained a multicopper oxidase gene probably responsible for iodide oxidation. A photosynthetic gene cluster was found but genes for carbon-fixation were absent.
Highlights
We report the draft genome sequence of strain Q-1, an iodide (I؊)-oxidizing heterotrophic bacterium in the class Alphaproteobacteria isolated from natural gas brine water
Iodide-oxidizing bacteria are able to oxidize iodide (IϪ) to molecular iodine (I2) and have been isolated from natural gas brine water containing very high concentrations (60 M to 1.2 mM) of iodide [1]. They are aerobic heterotrophic bacteria in the class Alphaproteobacteria and can be enriched from natural seawater supplemented with iodide, due to much higher I2 tolerance than the other heterotrophic bacteria in seawater [2]
Strain Q-1 was isolated from brine water in Miyazaki, Japan, and was phylogenetically related to the halophilic photosynthetic bacterium Rhodothalassium salexigens, with a 16S rRNA gene sequence similarity of 90% [1]
Summary
We report the draft genome sequence of strain Q-1, an iodide (I؊)-oxidizing heterotrophic bacterium in the class Alphaproteobacteria isolated from natural gas brine water. Iodide-oxidizing bacteria are able to oxidize iodide (IϪ) to molecular iodine (I2) and have been isolated from natural gas brine water containing very high concentrations (60 M to 1.2 mM) of iodide [1]. Such bacteria have been found to be involved in microbial clogging of well pipes in iodine-producing facilities [3, 4]. Strain Q-1 was isolated from brine water in Miyazaki, Japan, and was phylogenetically related to the halophilic photosynthetic bacterium Rhodothalassium salexigens, with a 16S rRNA gene sequence similarity of 90% [1].
