Far-Red Component Enhances Paramylon Production in Photoautotrophic Euglena gracilis

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

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 ...

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 ...

Development of screening strategies for the identification of paramylon-degrading enzymes

Journal of Industrial Microbiology and Biotechnology, 2019
Abstract Enzymatic degradation of the β-1,3-glucan paramylon could enable the production of bioactive compounds for healthcare and renewable substrates for biofuels. However, few enzymes have been found to degrade paramylon efficiently and their enzymatic mechanisms remain poorly understood.
