Abstract

Arenibacter sp. strain C-21, isolated from surface marine sediment of Japan, accumulates iodine in the presence of glucose and iodide (I-). We report here the draft genome sequence of this strain to provide insight into the molecular mechanism underlying its iodine-accumulating ability.

Highlights

Arenibacter sp. strain C-21, isolated from surface marine sediment of Japan, accumulates iodine in the presence of glucose and iodide (I-)
We isolated Arenibacter sp. strain C-21 from surface marine sediment collected from Sagami Bay, Kanagawa, Japan [2]
Subsequent studies revealed that glucose, oxygen, and calcium ion were required for iodine uptake by this strain [3]

Summary

Introduction

Arenibacter sp. strain C-21, isolated from surface marine sediment of Japan, accumulates iodine in the presence of glucose and iodide (I-). When strain C-21 was grown in the presence of 0.1 ␮M iodide ion (I-), it accumulated iodine with a maximum concentration factor of 5.5 ϫ 103. Subsequent studies revealed that glucose, oxygen, and calcium ion were required for iodine uptake by this strain [3]. Glucose-independent uptake of iodine was observed if a hydrogen peroxide-generating system or iodide-oxidizing system was present.
