Comparative Genome Analysis Provides Insights into Both the Lifestyle of Acidithiobacillus ferrivorans Strain CF27 and the Chimeric Nature of the Iron-Oxidizing Acidithiobacilli Genomes

Frontiers in Microbiology, 2017
The iron-oxidizing species Acidithiobacillus ferrivorans is one of few acidophiles able to oxidize ferrous iron and reduced inorganic sulfur compounds at low temperatures (<10°C). To complete the genome of At.

Sequence analysis of the riboflavin biosynthesis genes from acidithiobacillus ferrooxidans.

, 2006
Acidithiobacillus ferrooxidans is a bacteria with economic relevance in metal bioleaching. We describe here the sequence analysis of the riboflavin operon in this bacteria. Expression analysis of the rib genes was performed by Real-Time PCR.
