Consumption of Carbonyl Sulphide by Chlamydomonas reinhardtii with Different Activities of Carbonic Anhydrase (CA) Induced by Different CO2 Growing Regimes

Abstract

AbstractThe green alga, Chlamydomonas reinhardtii, was grown under high and low CO2 regimes inducing significantly different activities of the extracellular carbonic anhydrase (CA). In close relation to the CA activities, the algae exhibited different consumption rates of the climatically relevant atmospheric trace gas, carbonyl sulphide (COS), thus indicating that CA is responsible for uptake of COS from the medium.
