Wang, Hefei; Zhao, He-Ping; Zhu, Lizhong published an article in Environmental Science & Technology. The title of the article was 《Role of Pyrogenic Carbon in Parallel Microbial Reduction of Nitrobenzene in the Liquid and Sorbed Phases》.Name: ABTS Diammonium The author mentioned the following in the article:
Surface functional groups and graphitic C comprise the electroactive components of pyrogenic C. The role of pyrogenic C with different electroactive components content in mediating electron transfer in biochem. reactions has not been systematically studied. The authors determined the pyrogenic C electron exchange capacity was 0.067-0.120 mmol e-/g pyrogenic C with maximum elec. conductivity (EC) of 4.85 S/cm. Nitrobenzene was simultaneously reduced in liquid and sorbed phases by Shewanella oneidensis strain MR-1 in the presence of pyrogenic C. Pyrogenic C did not affect aqueous nitrobenzene reduction; reduction of sorbed nitrobenzene was much slower than that of the aqueous species. Enhancing the pyrogenic C oxygenated functional moiety content by HNO3 oxidation elevated bio-reduction rates of aqueous and sorbed species. Anthraquinone groups were deemed the most likely oxygenated functional redox compounds based on voltammetric curve tests and spectroscopic anal. Pyrogenic C reactivity for mediating sorbed nitrobenzene reduction was pos. correlated with its EC, which was demonstrated to be related to condensed aromatic structures. This work elucidated the mechanism for pyrogenic C-mediated biotransformation of nitrobenzene and helped properly evaluate the pyrogenic C role in biogeochem. redox processes occurring in nature. In the experiment, the researchers used ABTS Diammonium(cas: 30931-67-0Name: ABTS Diammonium)
ABTS Diammonium(cas: 30931-67-0) belongs to anime. Primary amines having a tertiary alkyl group (R3CNH2) are difficult to prepare with most methods but are made industrially by the Ritter reaction. In this method a tertiary alcohol reacts with hydrogen cyanide (HCN) in the presence of a concentrated strong acid; a formamide, RNH―CHO, is formed first, which then undergoes hydrolysis.Name: ABTS Diammonium
