This is in contrast to previous papers which have reported that this muscle is electrically inexcitable. It was found that an air supply to the muscle through the tracheoles is essential for maintaining its(More)
Cellular activity of nitrate reductase in Pseudomonas denitrificans which had been grown under denitrifying conditions was increased several times upon incubation of cell suspension with monovalent cations. The enhancement of nitrate reductase activity caused by monovalent cations was ascribed to the activation of the enzyme, since the membrane fraction(More)
