  • Rhodococcus jostii RHA1

Rhodococcus sp. RHA1 belongs to the actinobacteria . These are aerobic, gram - positive, acid-fast rods. With approx. 9.7 million base pairs, arranged in a linear chromosome and three linear plasmids , the genome is one of the largest bacterial genomes at all. The genome has been completely sequenced since October 2006.

The bacterial strain was assigned to the species Rhodococcus jostii as Rhodococcus jostii RHA1 , and it is also known as Rhodococcus sp. (strain RHA1) and Rhodococcus jostii strain RHA1. The term strain comes from English and means bacterial strain .

As a representative of the Actinomycetales order in the Actinobacteria department , Rhodococcus jostii RHA1 is one of the bacteria with a high GC content , i.e. a high proportion of the nucleobases guanine and cytosine in the bacterial DNA . Genetic testing showed a GC content of 67 mole percent. The genome of the bacterial chromosome is 7805 kilobase pairs (kb) in size . The strain investigated also has three plasmids , the size of which at 1123 kb, 443 kb and 332 kb, respectively, is significantly smaller compared to the bacterial chromosome, but which are remarkable for plasmids.

The organism is able to convert polychlorinated biphenyls (PCB) and can thus live on contaminated soil. On a soil contaminated with lindane, Rhodococcus sp. RHA1 has also been extracted.

An industrial use of Rhodococcus takes place via the production of bioactive steroids, acrylamide and acrylic acid (Banerjee, A. & Sharma, R. 2002). Due to their rapid growth rate, Rhodococci are also ideally suited to serve as an experimental system for Streptomyces or pathogenic relatives such as Mycobacterium tuberculosis (Gurtler, V. & Mayall, BC 2004).
