Figure 5From: Selenite reduction by the obligate aerobic bacterium Comamonas testosteroni S44 isolated from a metal-contaminated soil Comparison of Se(IV) and Se(VI) reduction and tungstate inhibition in C. testosteroni S44. Cultures were amended with 0.2Â mM Se(IV) (A), 5.0Â mM Se(VI) (B), respectively, and with or without 10Â mM tungstate. Tungstate did not inhibit Se(IV) reduction both in CDM, LB and TSB media whereas it inhibited Se(VI) reduction in all media.Back to article page
