Abstract
Respiration and dehydrogenase activity were studied in four pigmentless mutants of Staphylococcus aureus 209-P. The rate of oxygen uptake from the incubation medium was higher in the mutants than in the parent strain. The rate of respiration and the activity of dehydrogenase in the pigmentless mutants were found to depend on the permeability of the cell membrane for substrates of respiration; carotenoids are presumed to be involved in this permeability.
摘要
对金黄色葡萄球菌209 - P的四个无色素突变体的呼吸作用和脱氢酶活性进行了研究。突变体从培养液中摄取氧气的速率高于亲本菌株。发现无色素突变体的呼吸速率和脱氢酶活性取决于细胞膜对呼吸底物的通透性；据推测类胡萝卜素参与了这种通透性。
