Advances in Experimental Medicine and Biology, 2017
Motile microorganisms utilize a number of responses to external stimuli including light, temperature, chemicals as well as magnetic and electric fields. Gravity is a major clue to select a niche in their environment. Positive gravitaxis leads an organism down into the water column and negative gravitaxis brings it to the surface.

Large-Scale Cultivation of Euglena.
Advances in Experimental Medicine and Biology, 2017From the middle of the twentieth century, microalgae have been exploited as a candidate biomass source of food and other products. One such candidate source is the fast-proliferating microalga Euglena gracilis. The commercial cultivation of E. gracilis began in 2007, after the success of its outdoor mass cultivation and improvement of the harvesting ...

Biofuel production from Euglena: Current status and techno-economic perspectives.
Bioresource Technology, 2023Sustainable aviation fuels (SAFs) can contribute reduce greenhouse gas emissions compared to conventional fuel. With the increasing SAFs demand, various generations of resources have been shifted from the 1st generation (oil crops), the 2nd generation ...

Euglena gracilis (Euglena) is a microalgae found in most freshwater environments that produces paramylon, an insoluble β-1,3-glucan linked to human immunity. We hypothesized that Euglena powder has effects on immune function in apparently healthy adults.

Contamination of the environment by heavy metals is an increasing problem globally. While the mechanisms bacteria and yeasts have developed to tolerate these metals are well covered in the published literature, much less is known about algae.

Molecular tools and applications of Euglena gracilis: From biorefineries to bioremediation
Biotechnology and Bioengineering, 2020Euglena gracilis is a promising source of commercially important metabolites such as vitamins, wax esters, paramylon, and amino acids. However, the molecular tools available to create improved Euglena strains are limited compared to other microorganisms ...

Abstract When cells of Euglena gracilis are subjected to an external pH gradient or when photosynthesis occurs unequally within the cell so that one end is of higher pH than the other, they move topotactically in the direction of lower external pH or higher internal pH.

Euglena as a potential natural source of value-added metabolites. A review
Algal Research, 2019Microalgae-derived functional materials, such as food supplements, drugs, and biofuels have gained a great deal of attention in recent times. Among the several microalgae investigated for biomaterials production, Euglena spp.

Fluorescence Behavior of Euglena Photoreceptor¶
Photochemistry and Photobiology, 2003To provide new information on the series of structural changes that Euglena photoreceptive proteins undergo inside the photoreceptor in response to light, we measured in vivo emission fluorescence spectra in the stable intermediates of its photocycle.

Antimutagenicity in Euglena gracilis
Mutation Research Letters, 1994The genotoxic effect of N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) and furadantine (Fu) was significantly decreased by standard antimutagens (ascorbic acid, alpha-tocopherol, chlorophyllin and sodium selenite) in the unicellular flagellate Euglena gracilis. The effects of these compounds were verified also by a bacterial test in which three strains of
