    Metabolism of trimethylarsine oxide (1988)
    New York, NY [u.a.] : Wiley-Blackwell
    Applied Organometallic Chemistry 2 (1988), S. 479-482

    Topics: Chemistry and Pharmacology
    Notes: Trimethylarsine oxide [(CH3)3AsO] has been shown to be easily reducible by various biological species, including both aerobic and anaerobic micro-organisms, some skin organisms, soil bacteria, sludge and rumen fluid. The results suggest an enhanced mobility for arsenic owing to facile production of the volatile (CH3)3As species.

    The metabolism of methylarsine oxide and sulfide (1989)
    New York, NY [u.a.] : Wiley-Blackwell
    Applied Organometallic Chemistry 3 (1989), S. 71-78 
    Details
    ISSN: 0268-2605
    Keywords: Arsenic ; metabolism ; Candida humicola ; methylarsines ; methylarsine oxide ; methylarsine sulfide ; micro-organisms ; Chemistry ; Organic Chemistry

    Topics: Chemistry and Pharmacology
    Notes: Methylarsine oxide and sulfide are more toxic to Candida humicola than arsenite; the sulfide is rapidly metabolized to trimethylarsine (Me3As) and methylarsine (MeAsH2) and the oxide to dimethylarsinic acid [Me2AsO(OH)]. Cell-free extracts of C. humicola also convert the oxide to Me2AsO(OH). The glutathione (RSH) derivative Me2AsSR is metabolized by C. humicola to Me3As and Me2AsH, but some other Me2AsSR′ compounds are unaffected. Studies involving the interaction of the arsenic(III) compounds with natural ecosystems and other micro-organisms such as Scopulariopsis brevicaulis, Straptococcus sanguis, Escherichia coli, and Veillonella alcalescens are described.

    The uptake of arsenicals by Candida humicola (1990)
    New York, NY [u.a.] : Wiley-Blackwell
    Applied Organometallic Chemistry 4 (1990), S. 119-125 
    Details
    ISSN: 0268-2605
    Keywords: Arsenate uptake ; Candida humicola ; active transport ; arsenicals ; diffusion ; two-site model ; Chemistry ; Organic Chemistry
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: The uptake of arsenate by Candida humicola requires an active transport system and may operate through low- and high-affinity sites. Arsenite, methylarsonate and dimethylarsinate are deduced to enter the cell by slow passive diffusion.
