摘要： PURPOSE:To remove carbon dioxide and obtain a useful substance by assimilating and fixing the carbon dioxide contained in a waste gas, etc., with a protozoan of the genus Euglena. CONSTITUTION:This method for fixing carbon dioxide is to aerate a liquid culture medium for a protozoan of the genus Euglena with a gas such as a waste gas containing the carbon dioxide at various concentrations and assimilate and fix the carbon dioxide. The protozoan belonging to the genus Euglena is capable of assimilating even the carbon dioxide at a high concentration exceeding 50%.

摘要： PROBLEM TO BE SOLVED: To produce a large amount of trehalose useful as a humectant for cosmetics at a low cost by culturing a protozoan belonging to the genus Euglena, placing the cultured microbial cell under salt stress, osmotic pressure stress, etc., and then extracting the trehalose from the microbial cell. SOLUTION: A protozoan belonging to the genus Euglena (e.g. Euglena gracilis Z strain) is cultured in a Koren-Hutner culture medium at 26 deg.C under irradiation of light, at 2000 luxes for 4days by shaking culture and the resultant protozoans of the genus Euglena are then recovered and suspended in a 15mM phosphoric acid buffer solution (pH6.8). Sodium chloride as a salt, stress loading agent is added and sorbitol and sucrose as osmotic pressure loading agent are respectively added so as to provide 50mM sorbitol and 50mM sucrose. Thereby, the protozoans are placed under the salt stress and/or the osmotic pressure stress to extract, the produced trehalose from the microbial cell in an 80% aqueous solution of ethanol. The prepared extract, solution is then evaporated to dryness. Thereby, a large amount, of the objective trehalose useful as a humectant, etc., of cosmetics is obtained at a low cost.
