Polytomella coeca

Among other polysaccharides studied were those elaborated by Neisseria per-flava (starch-type polysaccharide), Polytomella coeca (a starch richer in amy-lopectin than most natural starches), Pseudomonas morsprunorum (Wormald) (levan), Acetobacter acetigenum (cellulose), Aerobacter aerogenes (NCTC 8172) (Klebsiella Type 164), Bacillus megaterium. Bacterium pruni, and Bacterium prunicola (polyfructoses of the levan type).

P-Enzyme was isolated from potato juice by Hanes in 1940 since then, preparations of various degrees of purity have been obtained from many higher plants. Potato P-enzyme has been intensively studied, and prepared in crystalline form. Extracts of the flagellate Polytomella coeca, which synthesizes a two-component starch, also contain P-enzyme. ... 

Chromatographic purifications of the RNA mononucleotides obtained by the ST or STS procedure from yeast (68), rat liver (9,27,32,54), mouse embryo (54), and Polytomella coeca (54) have been reported. Furst et al. (47) and Abrams et al. (1,2) describe methods of isolating chemically the nucleic acid products originally separated by modifications of the ST or S procedures. 

Soon after Cori and Cori showed the existence of a branching factor, Haworth, Peat, and Bourne reported the isolation from potato juice of an enzyme fraction termed Q-enzyme, which, in association with potato phosphorylase, produced a polysaccharide having the properties of amylopectin. Peat and his collaborators also presented evidence that the Q-enzyme was capable of converting linear amylose to branched amylopectin without the participation of inorganic phosphate in the reaction. They therefore concluded that the Q-enzyme is a nonphos-phorolytic enzyme. Besides being present in the potato, Q-enzyme has also been found in the wrinkled pea,the broad bean, Neisseria perfiava, and Polytomella coeca. " ...
