Mycelia of citric acid-producing Aspergillus niger WU-2223L show cyanide-insensitive respiration catalyzed by alternative oxidase. In this study, the constitutive expression of alternative oxidase gene (aox1) even at the stage of single-cell conidium in A. niger WU-2223L was found using the visual expression analysis system of aox1 with green fluorescent protein under microscopy observation.
产柠檬酸黑曲霉WU - 2223L的菌丝体表现出由交替氧化酶催化的氰化物不敏感呼吸作用。在本研究中,利用带有绿色荧光蛋白的交替氧化酶基因(aox1)的可视化表达分析系统,在显微镜观察下发现aox1在黑曲霉WU - 2223L的单细胞分生孢子阶段即组成性表达。
