The present invention provides an allergy inhibitor using the efficacy of amorphous paramylon which is a substance obtained by changing the crystalline structure of paramylon. The present invention relates to a substance for inhibiting allergic diseases. Amorphous paramylon of the present invention is an allergy inhibitor comprising amorphous paramylon which is obtained by amorphosizing crystalline paramylon derived from Euglena, and has a relative crystallinity of 20% or lower to the crystallinity of crystalline paramylon, determined by an X-ray diffractometry. This allergy inhibitor enables efficacious inhibition of allergic diseases such as atopic dermatitis, pollinosis, and the like.

Euglena gracilis, a microalgal species of unicellular flagellate protists, has attracted much attention in both the industrial and academic sectors due to recent advances in the mass cultivation of E. gracilis that have enabled the cost-effective production of nutritional food and cosmetic commodities. In addition, it is known to produce paramylon (β-1,3-glucan in a crystalline form) as reserve polysaccharide and convert it to wax ester in hypoxic and anaerobic conditions-a promising feedstock for biodiesel and aviation biofuel. However, there remain a number of technical challenges to be solved before it can be deployed in the competitive fuel market. Here we present a method for efficient selective breeding of live oil-rich E. gracilis with fluorescence-activated cell sorting (FACS). Specifically, the selective breeding method is a repetitive procedure for one-week heterotrophic cultivation, staining intracellular lipids with BODIPY505/515, and FACS-based isolation of top 0.5% lipid-rich E. gracilis cells with high viability, after inducing mutation with Fe-ion irradiation to the wild type (WT). Consequently, we acquire a live, stable, lipid-rich E. gracilis mutant strain, named B 1 ZFeL, with 40% more lipid content on average than the WT. Our method paves the way for rapid, cost-effective, energy-efficient production of biofuel.
