— Phycocyanin can sensitize the photobleaching of azo dyes in a reaction which is analogous to one sensitized by chlorophyll. The quantum yield of the phycocyanin‐sensitized photobleaching of congo red is low compared to the analogous reaction as sensitized by chlorophyll in aqueous pyridine. A kinetic mechanism for the former reaction is proposed and it was found that the manner in which phycocyanin sensitizes photoreduction of azo dyes is in several respects similar to that proposed for chlorophyll.
