Far-Red Component Enhances Paramylon Production in Photoautotrophic Euglena gracilis [PDF]

Bioengineering
In recent years, microalgae have gained significant biotechnological importance as a sustainable source of various metabolites of industrial interest. Among these, paramylon, a polysaccharide produced by the microalga Euglena gracilis, stands out for its

Safety of paramylon as a novel food pursuant to Regulation (EU) 2015/2283 [PDF]

EFSA Journal, 2023
Following a request from the European Commission, the EFSA Panel on Nutrition, Novel Foods and Food Allergens (NDA) was asked to deliver an opinion on paramylon as a novel food (NF) pursuant to Regulation (EU) 2015/2283. Paramylon is a linear, unbranched

Strategic Carbon Source Selection Enhances Biomass and Paramylon Yields in Mixotrophic Euglena gracilis Cultivation [PDF]

Microorganisms
Euglena gracilis’s mixotrophic metabolism offers biotechnological potential. This study investigated how glucose, sodium acetate, ethanol, and propanetriol regulate its growth, photosynthesis, and paramylon production.

Paramylon, a Potent Immunomodulator from WZSL Mutant of Euglena gracilis

Molecules, 2019
β-glucans, heterogeneous glucose polymers present in many organisms, have the capability to activate the innate immune system. Efficacy of activation depends on purity of the compound, molecular structure, polymerization degree, and source.

Enhancement of Growth and Paramylon Production of Euglena gracilis by Upcycling of Spent Tomato Byproduct as an Alternative Medium

Applied Sciences, 2021
Euglena gracilis (E. gracilis) accumulates paramylon, an immune-functional beta-glucan that can be used as a functional food. Paramylon production is strongly affected by the organic carbon source and the initial pH conditions. Food processing byproducts

A low temperature-adapted Euglena gracilis ecotype for outdoor biomass production in colder climates [PDF]

Applied and Environmental Microbiology
Euglena gracilis strain Z is currently used for industrial purposes such as the production of the polysaccharide paramylon, lipids, and carotenoids. This strain shows promise for sustainable bioproduction, but its growth is inhibited at temperatures ...

Melt processing of paramylon using a water:ionic liquid mixture as plasticizer

Carbohydrate Polymers, 2023
Paramylon is a linear β-1,3-glucan produced by the microalgae Euglena Gracilis. Due to its native crystalline structure, involving hexagonally packed triple helices, paramylon is neither water soluble nor thermoplastic. While such properties are generally obtained by chemical modification of paramylon, the present work demonstrates that using ionic ...

Melt spinnabilities of thermoplastic paramylon mixed esters [PDF]

Heliyon, 2019
The low thermoplasticities of polysaccharide esters make them unsuitable for melt spinning. In this study, we aimed to overcome this problem by mixed esterification of paramylon, a euglenoid β-1,3-glucan with short- and medium-chain acyl groups, as melt ...
