Sodium-dependent growth and respiration of a nonhalophilic bacterium, Pseudomonas stutzeri. 1976

T Kodama, and S Taniguchi

Pseudomonas stutzeri (van Niel strain) requires Na+ for growth. Its growth rate was a sigmoidal function of Na+ concentration, being maximal and constant from 2 to 50 mM-Na+, and half maximal at about 0-5 mM-Na+. The relationship between cell concentration and Na+ concentration was non-linear; cell concentration increased abruptly when Na+ was greater than 0-3 mM. Accumulation of Na+ in the organism during growth was not detected. In the presence of K+, respiration was enhanced specifically by Na+. The respiration rate of the organism growing in the culture was a linear function of the growth rate when limited by the Na+ concentration, whereas the maximum rate induced by excess Na+ was independent of the growth rate.

UI	MeSH Term	Description	Entries
D010101	Oxygen Consumption	The rate at which oxygen is used by a tissue; microliters of oxygen STPD used per milligram of tissue per hour; the rate at which oxygen enters the blood from alveolar gas, equal in the steady state to the consumption of oxygen by tissue metabolism throughout the body.

D011188	Potassium	An element in the alkali group of metals with an atomic symbol K, atomic number 19, and atomic weight 39.10. It is the chief cation in the intracellular fluid of muscle and other cells. Potassium ion is a strong electrolyte that plays a significant role in the regulation of fluid volume and maintenance of the WATER-ELECTROLYTE BALANCE.
D011549	Pseudomonas	A genus of gram-negative, aerobic, rod-shaped bacteria widely distributed in nature. Some species are pathogenic for humans, animals, and plants.	Chryseomonas,Pseudomona,Flavimonas
D012964	Sodium	A member of the alkali group of metals. It has the atomic symbol Na, atomic number 11, and atomic weight 23.	Sodium Ion Level,Sodium-23,Ion Level, Sodium,Level, Sodium Ion,Sodium 23
