L'angolo della Geologia: Stibnite
Stibnite - Antimonite. La stibnite Sb2S3 è un minerale, un solfuro di antimonio. Sono suoi sinonimi antimonite e stibina. Il nome stibnite deriva da stibio, voce desueta per antimonio, e (antimo)nite. Il nome stibina deriva dal greco στίβι = nero-antimonio, conosciuto già nell'antichità. Il nome antimonite deriva forse dall'arabo 'utmud.
Antimonite
Antimonite or arsenite activates ArsA ATPase activity. In the absence of the metalloids, ArsA has a low level of ATPase activity. Arsenite stimulates ATP hydrolysis by 3- to 5-fold, whereas a 10- to 20-fold stimulation is observed with antimonite as the activator. All other oxyanions tested had no effect on ATPase activity (Hsu & Rosen, 1989 ...

Arsenite transport into paddy rice ( Oryza sativa ) roots
Introduction. Studies on the kinetics of arsenic uptake into plant roots have focused almost entirely on arsenate as this is the dominant form of plant available arsenic in aerobic soils (Meharg & Hartley-Whitaker, 2002).In anaerobic soils arsenate is readily reduced to arsenite (undissociated arsenious acid, H 3 AsO 3) (Abedin et al., …

Chemolithotrophic Biological Nitrogen Fixation Fueled by Antimonite …
Nitrogen (N) deficiency in mining-contaminated habitats usually hinders plant growth and thus hampers tailing revegetation. Biological N fixation (BNF) is an essential biogeochemical process that contributes to the initial accumulation of N in oligotrophic mining-contaminated regions. Previous studies reported that chemolithotrophic rather …
