  • Uptake of glycine by natural phytoplankton communities

    Creator:
    Wheeler, Patricia A., North, B., Littler, M., and Stephens, G.
    Abstract:
    Uptake of [14C]glycine by various size fractions of natural plankton communities was measured to determine if phytoplankton can compete effectively with other members of the plankton community for the free amino acids in seawater. The simultaneous occurrence of glycine uptake, plant pigments, and photosynthetic activity in the same size fractions,...

  • Amino acid uptake by marine phytoplankters

    Creator:
    Wheeler, Patricia A., North, Barbara B., and Stephens, Grover C.
    Abstract:
    Axenic cultures of 25 species of unicellular marine algae were tested for their ability to utilize nine common amino acids, supplied at high concentrations in batch culture, as a nitrogen source; most species were able to use several amino acids, although growth was often slower than on nitrate nitrogen. The...
