||"The internal sodium concentrations estimated in the marine bacteria were two to eight times lower than the concentration in the external water (Table 2). The highest sodium concentration was found in growing V. natriegens (400 mM), and lowest was found in the Knebel Vig 1992 sample (49 mM). It is noteworthy that the marine samples from Knebel Vig had concentrations equal to or lower than that of the freshwater sample from lake Kalandsvatnet and cultures of E. coli. An increase in sodium concentration of cells entering the stationary phase has been shown for cultured bacteria (Cirillo 1966 Sadler et al. 1980 Oren et al. 1997). The dormant bacteria in the October sample from Raunefjorden reacted to substrate addition by reducing the cellular sodium concentration within 6h of incubation (Tuomi et al. 1995). For V. natriegens, the opposite change in sodium content of growing versus stationary cells was seen (Table 2). [Researchers] have no explanation to this." fg=femtogram=10^-15 gram.
