Heterotrophic Carbon Dioxide Fixation Products of Euglena: EFFECTS OF AMMONIUM 1
AUTOR(ES)
Peak, Jennifer G.
RESUMO
The metabolic products of heterotrophic (dark) CO2 fixation by Euglena gracilis Klebs strain Z Pringsheim were separated and identified. They consisted of amino acids, phosphorylated compounds, tricarboxylic acid cycle intermediates, and nucleotides. Exposure of the cells to NH4+ after a period of NH4+ deprivation stimulated heterotrophic CO2 fixation almost 4-fold, modifying the spectrum of the fixation products. In particular, the NH4+ treatment stimulated fixation of CO2 into glutamine, glycine, alanine, and serine.
