Complete genome sequence of Acidithiobacillus ferrooxidans YNTRS-40, a strain of the ferrous iron- and sulfur-oxidizing acidophile

Acidithiobacillus ferrooxidans YNTRS-40 ( A. ferrooxidans ) is a chemolithoautotrophic aerobic bacterium isolated from Tengchong, Yunnan Province, China and with a broad growth pH range of 1.0-4.5. This study reported the genome sequence of this strain and the information of genes related to the adaptation of diverse stresses and the oxidation of ferrous iron and sulfur. Results showed that YNTRS-40 possesses chromosomal DNA (3,209,933-bp) and plasmid DNA (47,104-bp). The complete genome of 3,257,037-bp was consist of 3349 CDS genes comprising 6 rRNAs, 52 tRNAs and 6 ncRNAs. There are many encoded genes associated with diverse stresses adaptation and ferrous iron and sulfur oxidation such as rus operon, res operon, pet Ⅰ , pet Ⅱ , sqr gene, doxDA , cydAB and cyoABCD . This study will provide essential information for further application of A. ferrooxidans YNTRS-40 in industry.
