This paper describes the use of the Blue-RAT in determining values of photosynthetic absorptance, a requirement for the calculation of Electron Transport Rate (ETR). As Afifella marina is a unicellular organism (a purple nonsulphur anoxygenic photobacterium), cells were filtered onto glass fibre filters prior to absorptance measurements. Implications of the research include a more accurate method for calculating ETR of unicellular algae, and a means of assessing the rates of H2 production and nitrogen fixation by anoxygenic photobacteria (both clearly important commercial activities).
