Bacteriochlorophylls ( BChl ) are photosynthetic pigments that occur in various phototrophic bacteria . They were discovered by C. B. van Niel in 1932 . [ 1 ] They are related to chlorophylls , which are the primary pigments in plants , algae , and cyanobacteria . Organisms that contain bacteriochlorophyll conduct photosynthesis to sustain their energy requirements , but do not produce oxygen as a byproduct . They use wavelengths of light not absorbed by plants or Cyanobacteria . Replacement of Mg2+ with protons gives bacteriophaeophytin ( BPh ) , the phaeophytin form .
