Abstract

Rhodococcus sp. B7740 was isolated from Arctic seawater and selected for its capacity to synthesize carotenoids. Here, we report the complete genome sequence of Rhodococcus sp. B7740 to provide the genetic basis for a better understanding of its carotenoid-accumulating capabilities, and we describe the major features of the genome.

Highlights

Increasing research has recently focused on the modification of wild strains of microorganisms by genetic engineering in order to increase their production of carotenoids [2], including metabolic engineering of Rhodococcus [3]
B7740 is a psychrotolerant, carotenoid-producing bacterium isolated from Arctic seawater [4]
We report the complete genome sequence of Rhodococcus sp

Summary

Introduction

Carotenoids are noted for their antioxidant and anticancer abilities, as well as for boosting the immune system and for other effects. Carotenoids have attracted extensive attention as a natural food additive [1]. Microbial fermentation is currently the healthiest and easiest way of producing carotenoids, though production of wild strains of microorganisms still needs to be improved. Increasing research has recently focused on the modification of wild strains of microorganisms by genetic engineering in order to increase their production of carotenoids [2], including metabolic engineering of Rhodococcus [3]. B7740 is a psychrotolerant, carotenoid-producing bacterium isolated from Arctic seawater [4].
