Abstract: We report production of chlorophyll f and chlorophyll d in the cyanobacterium Chlorogloeopsis fritschii cultured under near-infrared and natural light conditions. C. fritschii produced chlorophyll f and chlorophyll d when cultured under natural light to a high culture density in a 20 L bubble column photobioreactor. In the laboratory, the ratio of chlorophyll f to chlorophyll a changed from 1:15 under near-infrared, to an undetectable level of chlorophyll f under artificial white light. The results provide support that chlorophylls f and d are both red-light inducible chlorophylls in C. fritschii.
Item Description: This paper is the first to report chlorophylls d and f, pigments that absorb in the near-infrared region of the spectrum, isolated in a known species of cyanobacteria cultivated in a photobioreactor. This potentially has implications in terms of improving productivity in algal cultivation systems required for industrial biotechnology.
