As a result, Brooks has his eye on a natural gold releaser, a soil bacterium called Thiobacillus ferro-oxidans, that may be able to help his plants go about their business without some of the economic ( and environmental ) drawbacks of his present method.

In presence of oxygen, aerobic bacteria like " Acidithiobacillus thiooxidans ", " Thiobacillus thioparus ", and " Thiobacillus concretivorus ", all three widely present in the environment, are the common corrosion-causing factors resulting in biogenic sulfide corrosion.

""'Acidithiobacillus caldus " "'formerly belonged to the genus " Thiobacillus " prior to 2000, when it was reclassified along with a number of other bacterial species into one of three new genera that better categorize sulfur-oxidizing acidophiles.

Little is known of the nature of the association ( mode of infection, transmission, metabolic requirements, etc . ) but phylogenetic analysis indicates that these symbionts belong to the alpha group of the class Proteobacteria, relating them to " Rhizobium " and " Thiobacillus ".

""'Acidithiobacillus thiooxidans " "', formerly known as " Thiobacillus thiooxidans " until its reclassification into the newly designated genus " Acidithiobacillus " of the gamma subclass of Proteobacteria, is a Gram-negative, rod-shaped bacterium that uses sulfur as its primary energy source.

If an affected area is treated with sulfur and " Thiobacillus " spp ., the bacteria oxidise the sulfur to sulfuric acid, which destroys the pest, as the potato scabs cannot tolerate acidic conditions . " Thiobacillus thioparus " may contribute to the formation of acid rain through the oxidation of sulfur dioxide to sulfurous acid.

DNA hybridization studies have revealed that strains KU and BC13 exhibited 100 % homology with each other, yet showed no DNA hybridization of significance ( 2-20 % ) with other species in the genus including " A . ferrooxidans " and " A . thiooxidans ", or with other similar Proteobacteria, such as " Thiomonas cuprina " or " Thiobacillus thioparus ".

Basal species can be autotrophs or detritivores, including " decomposing organic material and its associated microorganisms which we defined as detritus, micro-inorganic material and associated microorganisms ( MIP ), and vascular plant material . " Most autotrophs capture the sun's energy in chlorophyll, but some autotrophs ( the chemolithotrophs ) obtain energy by the chemical oxidation of inorganic compounds and can grow in dark environments, such as the sulfur bacterium " Thiobacillus ", which lives in hot sulfur springs.
