Unique Dynamics of Paramylon Storage in the Marine Euglenozoan Diplonema papillatum
Protist, 2020Diplonemids belong to the most diverse and abundant marine protists, which places them among the key players of the oceanic ecosystem. Under in vitro conditions, their best-known representative Diplonema papillatum accumulates in its cytoplasm a crystalline polymer.

STRUCTURE OF THE EUGLENOID STORAGE CARBOHYDRATE, PARAMYLON
American Journal of Botany, 1987Paramylon, the euglenoid storage carbohydrate, was studied by transmission electron microscopy (thin sectioning, negative staining, and freeze‐etching) and scanning electron microscopy in order to develop a three‐dimensional model of paramylon structure.

Crystal transition of paramylon with dehydration and hydration
Carbohydrate Polymers, 2010Abstract The structure of paramylon, a highly crystalline (1 → 3)-β- d -glucan material, was analyzed by synchrotron X-ray powder diffraction and solid-state 13 C NMR spectroscopy. Native paramylon, the hydrate with high crystallinity, was converted into the anhydrous form by drying, by which the crystallinity decreased and the molecular ...

ABSTRACTParamylon is the β‐1, 3‐glucan storage product in euglenoid algae. It is a fibrous crystal that occurs as membrane‐bound granules in the cytosol. The role of the surrounding membrane in paramylon synthesis was investigated by the use of freeze‐etch electron microscopy.

Thermal expansion behavior of hydrate paramylon in the low-temperature region
Carbohydrate Polymers, 2013The thermal expansion behavior of hydrate paramylon between 100 and 300K has been investigated using synchrotron X-ray powder diffraction. The X-ray diffraction profile at 300K showed a typical pattern of the hydrate triple helical (1→3)-β-d-glucan with a hexagonal unit cell (a=15.782Å and c=18.580Å).

Preparation of Paramylon Multifilament by Using the Viscose Method
ChemistrySelect, 2022Abstract The feasibility of preparing a novel wet‐spun multifilament derived from paramylon‐a linear β‐1,3‐glucan‐is investigated in this study. The decomposition temperature of the paramylon multifilament (∼300 °C) exceeds that of a wet‐spun cellulose one (∼270 °C).

Stress resistance induced by paramylon treatment in Artemia sp.
Journal of Applied Phycology, 2004A study was undertaken to investigate the effectiveness of paramylon extracted from the non-photosynthetic WZSL mutant of Euglena gracilis in potentiating the resistance of the brine shrimp Artemia sp. to stress conditions resulting from poor growth medium quality and daily handling.
