Abstract

Chloroplast thylakoids are immobilized within a calcium alginate gel layer-The photoassisted activity of the preparation is measured by following the reduction of DCPIPox, an artificial electron acceptor. Under illumination wavelengths ranging between 600 and 700 nm, the DCPIPox absorbs strongly. Thus, when traversing the acceptor solution before impinging upon the membrane, a part of the incident light intensity is absorbed according to a (decreasing) exponential law. The coupling between the light absorbance and the photoassisted reaction leads to an autocatalytic effect: An inhibition by excess DCPIPox is observed. When working under open conditions (CSTR), multiple steady-states occur with respect to either the DCPIPox concentration or the incident light intensity, as demonstrated experimentally.
