TABLE 2.
Properties of White Point VAF and a control, vacuolate Carmel Canyon Beggiatoa sp.
| Sample | Date collected | Protein/biovolume (mg of protein/cm3) | Internal nitrate concn (mM)a,b | Internal phosphate concn (mM)b |
| VAF | 11 July 2001 | 6.8 | Not detected | 1.1 |
| VAF | 28 February 2002 | 8.4 | Not detected | 0.5 |
| Carmel Canyon Beggiatoa sp. | 24 September 2002 | 8.9 ± 1.1 | 16.6 ± 4 | 0.2 ± 0.04 |
a Not detected, 5 μM concentration for column and conductivity detector is implied. Necessary dilution of original pellet for (i) disruption of cells and (ii) column removal of interfering Cl− implies true detection threshold of approximately 800 μM internal NO3.
b Calculated by assuming anion distributed over cytoplasm and vacuole.
