1941 R. P. Hall in G. N. Calkins & F. M. Summers Protozoa in Biol. Res. ix. 477 Some [chlorophyll-bearing protozoa] appear to be obligate phototrophs.
1965 A. H. Rose Chem. Microbiol. iii. 39 Only a minority of micro-organisms including algae and photosynthetic bacteria and protozoa are able to utilize directly the energy of solar radiation. These organisms are described as phototrophs to distinguish them from chemotrophs.
1975 Nature 7 Aug. 463/2 This versatility would give it a clear advantage over other blue-green algae (mostly obligate phototrophs) as well as over bacteria.
