AbstractNineteen fungal strains having an ability to oxidize elemental sulfur in mineral salts medium were isolated from deteriorated sandstones of Angkor monuments. These fungi formed clearing zone on agar medium supplemented with powder sulfur due to the dissolution of sulfur. Representative of the isolates, strain THIF01, was identified as Fusarium solani on the basis of morphological characteristics and phylogenetic analyses. PCR amplification targeting 16S rRNA gene and analyses of full 16S rRNA gene sequence indicated strain THIF01 harbors an endobacterium Bradyrhizobium sp.; however, involvement of the bacterium in the sulfur oxidation is still unclear. Strain THIF01 oxidized elemental sulfur to thiosulfate and then sulfate. Germination of the spores of strain THIF01 was observed in a liquid medium containing mineral salts supplemented with elemental sulfur (rate of germinated spores against total spores was 60.2%), and the culture pH decreased from pH 4.8 to 4.0. On the contrary, neither germination (rate of germinated spores against total spores was 1.0%) nor pH decrease was observed without the supplement of elemental sulfur. Strain THIF01 could also degrade 30 ppmv and ambient level (approximate 500 pptv) of carbonyl sulfide. © 2010 Springer Science+Business Media, LLC.
