Denitrifying Pseudomonas aeruginosa: some parameters of growth and active transport.

摘要: Optimal cell yield of Pseudomonas aeruginosa grown under denitrifying conditions was obtained with 100 mM nitrate as the terminal electron acceptor, irrespective medium used. Nitrite acceptor supported poor growth when concentrations less than 15 mM, but not higher, were used, apparently owing to toxicity exerted by nitrite. accumulated in during early exponential phase and then decreased extinction before midexponential phase. The maximal rate glucose gluconate transport 1 or nitrite anaerobic conditions. greater greatest observed aerobic oxygen acceptor. When P. inoculated into a environment, reductase detected after 3 h incubation, another 4 activities peaked together latter coincided activity.
