Vibrio succinogenes grew anaerobically at the expense of formate oxidation, with nitrous oxide (N2O) serving a terminal oxidant. N2O was quantitatively reduced to dinitrogen (N2). In the presence of 5 x 10(-2) atm (ca. 5 kPa) of acetylene (C2H2), which inhibits the reduction of N2O, growth of V. succinogenes was completely inhibited. Nitrate was reduced to nitrite or to ammonia, depending on the extent of availability of formate, but N2 was not produced by reduction of nitrate. During the reduction of nitrate to ammonia, all eight electrons transported to a molecule of nitrate appeared to be coupled for energy-yielding reactions.
琥珀酸弧菌在以甲酸氧化为代价的情况下进行厌氧生长,一氧化二氮(N₂O)作为末端氧化剂。N₂O被定量还原为氮气(N₂)。在存在5×10⁻²个大气压(约5千帕)乙炔(C₂H₂)的情况下,乙炔会抑制N₂O的还原,琥珀酸弧菌的生长被完全抑制。硝酸盐根据甲酸的可利用程度被还原为亚硝酸盐或氨,但硝酸盐还原不会产生N₂。在硝酸盐还原为氨的过程中,传递到一分子硝酸盐的所有八个电子似乎都被耦合用于产能反应。
