“…Falk & Kleinig (1968) claimed that Tribonema had the same pigments as Vaucheria and Botrydium, except that the minor xanthophyll cryptoxanthin was missing. Whittle & Casselton (1969) agreed with them and also suggested that the pigments of Mischococcus sphaerocephalus resembled those of Tribonema. It now appears that the pigment which was isolated by both Kleinig & Egger (1967) and Whittle & Casselton (1969) and identified as antheraxanthin is, in fact, the closely related xanthophyll diadinoxanthin (Strain et al, 1968(Strain et al, , 1970Egger et al, 1969;Stransky & Hager, 1970a).…”

Stransky & Hager (1970a) used a very sensitive system of thin-layer chromatography (TLC) in conjunction with infrared spectroscopy and microchemical tests for identifying functional groups to study the carotenoids of eight members of the Xanthophyceae sensu stricto.…”

“…Several attempts had been made to identi~ the chloroplast pigments of the Xanthophyceae (Kuhn & Brockman, 1932;~arter, Heilbron & Lythgoe, 1939;Seybold, Egle & Hiilsbruch, 1941 ;Heilbron, 1942;Strain, Manning & Hardin, 1944;Jamikorn, 1954;Strain, 1958;gestfik, 1963;Allen et al, 1964;Thomas & Goodwin, 1965;Chapman & Haxo, 1966) before Kleinig & Egger (1967) reported that Vaucheria and Botrydium contained p-carotene, chlorophyll a, antheraxanthin, three tri-esters of the previously undescribed xanthophyll vaucheriaxanthin, an unknown pigment which was subsequently identified by Falk & Kleinig (1968) as trollixanthin, and traces of cryptoxanthin epoxide and zeaxanthin, the latter pigment being produced by a light-induced conversion of antheraxanthin (Kleinig, 1967). Subsequent studies largely fall into two groups, those primarily dealing with the correct identification of the pigments (Falk & Kleinig, 1968;Egger, Nitsche & Kleinig, 1969;Strain et al, 1968Strain et al, , 1970Stransky & Hager, 1970a) and those primarily concerned with recognition of the fact that some of the unicellular forms belong to a separate taxonomic group (Whittle & Casselton, 1969, 1975Guillard & Lorenzen, 1972) corresponding to the Eustigmatophyceae of Hibberd & Leedale (1970, 1971b, 1972. Falk & Kleinig (1968) claimed that Tribonema had the same pigments as Vaucheria and Botrydium, except that the minor xanthophyll cryptoxanthin was missing.…”

“…In addition, the authentic strain of Chlorocloster engadinensis Vischer (SAG 812-1), which was originally described as a xanthophyte (Vischer, 1945) was also included in the analyses. However, in addition to chlorophyll a, Whittle & Casselton (1969) found chlorophyll b in that strain, indicating its membership of the green lineage. Moreover, Chlorocloster engadinensis is morphologically similar to Chlorella saccharophila.…”

Ellipsoidal Chlorella-like species are very common in all kinds of aquatic and terrestrial habitats, and often identified as Chlorella saccharophila or C. ellipsoidea. However, the taxonomic status of these species remains unclear, because they are not related to the type species of the genus, Chlorella vulgaris. In this study, 23 strains isolated from different habitats, were investigated using a polyphasic approach, i.e. morphology and reproduction, ecophysiology, and combined SSU and ITS rDNA sequences. Phylogenetic analyses clearly demonstrated that these isolates formed a monophyletic lineage within the green algal class Trebouxiophyceae. All strains were characterized by ellipsoidal cell shape, unequal autospores during reproduction, and parietal chloroplasts, as well as by the biochemical capability to synthesize and accumulate the rather unusual polyol, ribitol. Although ribitol is a typical stress metabolite involved in osmotic acclimation, it can also be used as a chemotaxonomic marker. Comparative growth measurements under different temperature regimes indicated similar optimum growth temperatures and maximum growth rates in all studied Chlorella-like species. However, these were different from those of C. vulgaris. We therefore propose to transfer all Chlorella-like strains related to Chlorella saccharophila and C. ellipsoidea to the genus Chloroidium Nadson and to emend its diagnosis. We propose four new combinations: Chloroidium saccharophilum comb. nov., Chloroidium ellipsoideum comb. nov., Chloroidium angusto-ellipsoideum comb. nov. and Chloroidium engadinensis comb. nov. In contrast, Chlorella ellipsoidea sensu Puncˇocha´rova´, which has other morphological and ecophysiological characters, should be assigned to the genus Pseudochlorella (P. pringsheimii comb. nov.).

“…Species which can be placed with certainty in the Eustigmatophyceae are: This split is based on morphological criteria but is supported biochemically by the recently published work of Whittle and Casselton (1969) on the pigments of some Xanthophyceae. They found that the data for three forms here included in the Eustigmatophyceae, Pleurochloris commutata, Pleurochloris magna and Polyedriella helvetica (same isolates as used for the present study) were clearly different from those obtained from Tribonema aequale (a true xanthophycean species); in these forms, antheraxanthin, the major xanthophyll in T. aequale, is replaced by a pigment corresponding in absorption spectrum and Rf values to violaxanthin.…”
