Properties of selectively starved Euglena

Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1967
Abstract It has been shown that starving Euglena for an essential nutrient causes it to reduce its nuclear and plastid complements by one-half. If pressed by extreme deprivation of the nutrient, the cell is finally pushed to discard its plastid complement which is gratuitous in the heterotrophic medium in which the cell is growing.

Biochemistry and Physiology of Vitamins in Euglena

2017
Euglena gracilis Z requires vitamins B1 and B12 for growth. It takes up and accumulates large amounts of these exogenous vitamins through energy-dependent active transport systems. Except for these essential vitamins, E. gracilis Z has the ability to synthesize all human vitamins. Euglena synthesizes high levels of antioxidant vitamins such as vitamins

Euglena: The Photoreceptor System for Phototaxis*

The Journal of Protozoology, 1977
SYNOPSIS. The photoreceptor structures (eyespot‐paraflagellar body‐flagellum) for Euglena phototaxis were investigated by electron microscopy. The paraflagellar body—the photoreceptor—is a highly ordered crystalline lamellar structure. Optical diffraction of the electron micrographs and resulting filtered images of the paraflagellar body suggest that ...

Laminarase of Euglena gracilis

Science, 1960
An enzyme in extracts of the protistan Euglena gracilis splits the polysaccharide laminarin (β-1:3-glucosan). Its optimal p H is 5.0, and it is activated by Mn ++ ions.

Euglena gracilis Subcellular Fractionation

Subcellular fractionation of Euglena gracilis has been conducted for over 50 years in various forms by numerous research groups. The development of this technique is closely tied to the specific organelle or fraction required for specific purposes.
