Measurement of Algal Photosynthesis Using a Clark-Type O2 Electrode

Methods Mol Biol. 2024:2790:121-132. doi: 10.1007/978-1-0716-3790-6_7.

Abstract

The Clark-type electrode can be used to assess the rates of photosynthesis by detecting changes in O2 concentration in a culture. This chapter describes a method for a liquid phase measurement of light and dissolved inorganic carbon-dependent photosynthesis using the model green alga Chlamydomonas reinhardtii. The technique can be used to evaluate the presence or efficiency of carbon-concentrating mechanisms.
