Conversion of nitrite of nitrate by nitrite-resistant yeasts.
Agricultural and Biological Chemistry, 1988 Candida species YK 11 and YK 92 and Geotrichum candidum YK 57, which were isolated as nitrite-resistants, converted nitrite in the culture medium to nitrate stoichiometrically during growth. The nitrite-oxidizing reaction was confirmed under aerobic conditions in the intact cell system with 15mM nitrite, 150mM glucose, and 100mM Tris-HCl buffer (pH 7.0)

Nitrate Reduction to Nitrite, a Possible Source of Nitrite for Growth of Nitrite-Oxidizing Bacteria [PDF]
Applied and Environmental Microbiology, 1977 Growth yields and other parameters characterizing the kinetics of growth of nitrite-oxidizing bacteria are presented. These parameters were measured during laboratory enrichments of soil samples with added nitrite. They were then used to reanalyze data for nitrite oxidizer growth in a previously reported field study (M. G. Volz, L.

Advanced Functional Materials, EarlyView.Sulfur‐doped graphitized carbon nanofibers act as adaptive catalyst–support platforms, enabling dynamic sulfur‐mediated reconstruction and strong metal–support interactions. This unique behavior enhances catalyst stability and controls reaction pathways, achieving highly selective urea oxidation (∼92% N2) coupled with efficient hydrogen evolution ...
