Italian term

batteri solfossidanti

Italian to English Tech/Engineering Chemistry; Chem Sci/Eng oxidation
Hi guys,

Dealing with corrosion of plaster due to microbial attack. This sort of bacteria appears on a list of corrosive elements. Any guess to what it is?
Thanks

Discussion

Armand C. Sep 26, 2009:
I beg to disagree. The term, "solfossidanti", indicates clearly enough that it's about OXIDIZING the sulphur. <br>"Sulphur metabolizing" is indeed a "cover all term", but precisely for this reason it's inappropriate here. Metabolization of sulphur comprises both oxidizing and reducing sulphur -- processes that occur in different conditions and with different bacteria species. (The oxidizing species are aerobic and convert H2S or the S2- ion to sulphates, while the reducing ones are anaerobic and determine the very opposite process.)
Dr Lofthouse Sep 25, 2009:
I'd think I'd use 'sulfur metabolizing bacteria' as a cover all term , as there is doubt regarding the substrate (sulphide , sulphur, sulphate etc) and because corrosion is caused by oxidation and reduction -

Thank you, Cedric!
disagree Armand C. : Ridurre i solfati e proprio, chimicamente, la reazione opposta all'ossidazione dell'acido solfidrico. Inoltre, Thiobacillus ed Acidothiobacillus NON sono la stessa specia.

sulfur-oxidizing bacteria

a sulfur oxidizing bacteria (SOB), primarily genus Thiobacillus aerobic bacteria, which colonize on pipe crowns, walls, and other surfaces above the waterline in wastewater pipes and structures, metabolize the H2S gas and oxidize it to H2SO4. This oxidizing process can take place where there is an adequate supply of hydrogen sulfide gas greater than 2 ppm, high relative humidity, and atmospheric oxygen.

http://en.wikipedia.org/wiki/Biogenic_sulfide_corrosion

The stability of cement in the environment may be impaired by sulfur-oxidizing bacteria that corrode the cement by producing sulfuric acid.
