Pseudomonas aeruginosa PAO1 reduced nitrous oxide to dinitrogen but did not grow anaerobically in nitrous oxide. Two transposon insertion Nos- mutants of Pseudomonas stutzeri exhibited the P. aeruginosa phenotype. Growth yield studies demonstrated that nitrous oxide produced in vivo was productively respired, but nitrous oxide supplied exogenously was not. The defect may be in electron transport or in nitrous oxide uptake.
铜绿假单胞菌PAO1可将一氧化二氮还原为氮气,但在一氧化二氮中不能厌氧生长。两个施氏假单胞菌转座子插入Nos-突变体表现出铜绿假单胞菌的表型。生长产量研究表明,体内产生的一氧化二氮可被有效呼吸利用,但外源供应的一氧化二氮则不能。缺陷可能在于电子传递或一氧化二氮摄取。
