“…This metabolic decrease would affect absorption of all ions, cation as well as anion; the decrease is in agreement with findings of Trelease and Trelease (9), as well as data reported above. However, nitrate is affected to a greater extent than are the other cations and anions: in one instance this resulted in an unmeasurable absorption of NOo-at 13 C. From …”

“…A previous report of JUDKINS (6) In all treatments the nitro(gen was supplied in rates of 4 parts of NaNO3 to 1 part (NH4)2 SO4 as a means of maintaining the nutrient solution at slightly below pH 6.0, in accordance with the results reported by TRELEASE arid TRELEASE (8).…”

“…These effects have been inferred for many years (Trelease and Trelease 1935;Cramer and Myers 1948;Rcdfield ct al. 1963;Richards 1965;Berner et al 1970;Gaines and Pilson 1972) and indeed are implicit in the Redficld-Ketchum-Richards phytoplankton equations.…”

Continuous cultures of three marine phytoplankton species, Phaeodactylum tricornutum, Dunaliella tertiolecta, and Monochrysis lutheri, were monitored for changes in alkalinity of the culture medium resulting From NO, and NHa+ uptake. Uptake of NO,-caused an increase in alkalinity, whereas uptake of NH,+ produced a decrease. These results are consistent with the type of schematic equation proposed by Redfield, Ketchum, and Richards for photosynthetic assimilation of inorganic nitrogen, in which NO, uptake is balanced by OH-production and NHa+ uptake leads to H+ generation. These reactions suggest active uptake of nitrogen species by microbes. We have been unable to demonstrate the exact stoichiometry of this relationship, and the role of P uptake in the alkalinity change is unclear. An offset in the data, functionally equivalent to the production of some strong acid, may be due to reactions on the walls of the vessel, active uptake of cations, or extrusion of H' ions by the growing cells.
