摘要：

The storage glucans of Chlorella pyrenoidosa and Prototheca zopfii are identical and consist of a linear polyglucan akin to amylose and a branched amylopectin component. The branched glucans of these algae differ markedly from that formed by the hot-springs alga, Cyanidium caldarium. The more highly branched Cyanidium glucan appears to be formed by branching glucosyltransferases which are different from those of the other two algae. The relevance of the data to the possibility of Cyanidium being a Prototheca-like Chlorella that has acquired symbiotic Cyanobacteria as chloroplasts is discussed. © 1979.
