V. The Auxotrophie and Mesotrophic Species Summary. 16 non-autotrophic Chlorella strains were found to be auxotrophic (i.e., require thiamine). 14 of these strains are also mesotrophie (i.e., unable to utilize nitrate).
Chlorella protothecoides Krfiger (14 strains) does not contain hydrogenase, is unable to reduce nitrate, does not liquefy gelatin, does not synthesize secondary carotenoids when nitrogen is deficient, loses its chlorophyll when grown in the presence of glucose, and reaches its limit of growth at pH 3.5--4.0.
The two other strains contain hydrogenase, are able to use nitrate as a source of nitrogen, do not liquefy gelatin, do not synthesize secondary carotenoids, do not lose their chlorophyll when grown in the presence of glucose, and reach their limit of growth at pH 4.5--5.0. They are designated as Chlorella VI.
