Abstract
The rates of uptake of five amino acids - alanine, glutamate, glycine, leucine and serine - by axenic cultures of the cyanobacterium Planktothrix rubescens were measured over a range of irradiances using the 14C-labelled amino acids at the nanomolar concentrations observed in Lake Zürich. The rates in the light exceeded the dark rates by as much as two- to ninefold. The light-affinity constants for stimulation were similar, indicating a similar process for each of the five amino acids. The Ek (light saturation irradiance) for light st
