Provided are a prophylactic or therapeutic agent for a peptic ulcer, a food additive for prevention and treatment of a peptic ulcer, an iNOS expression inhibitor, and a COX-2 expression inhibitor, all of which have little side effects. The prophylactic or therapeutic agent contains a-derived material as an active ingredient. The-derived material may be, paramylon, or an acid-treated paramylon. The prophylactic or therapeutic agent is useful for the prevention or treatment of a peptic ulcer induced by psychological stress. The peptic ulcer may be a gastric ulcer. The food additive contains a-derived material as an active ingredient.

Prophylactic or therapeutic agent for peptic ulcer, food additive for prophylactic or therapeutic use, iNOS expression inhibitor and COX-2 expression inhibitor

An algae culture method capable of efficiently producing an osmotic pressure adjusting substance, a production method of the substance, and an algae culture method for recovering carbon dioxide from a mixed gas containing carbon dioxide and sulfurous acid gas. The methods involve preparing a plurality of enrichment cultures each containing betaine by culturing a culture of microalgae derived from an environmental specimen under a photoautotrophic condition and under a plurality of culture conditions; making a cultivation plan in which an optimum enrichment culture suitable for a main culture is selected from the plurality of enrichment cultures; producing a main culture that contains betaine under the photoautotrophic condition and a salt concentration of 10 wt. % or more; and separating betaine. In the main culture, the algae containing betaine are cultured while the mixed gas containing sulfurous acid gas and carbon dioxide is blown to a culture solution of the algae.

A &#x3b2;-1,3-glucanase that exhibits decomposition activity with respect to paramylon derived from the genus. The &#x3b2;-1,3-glucanase is derived from the genusand exhibits the properties indicated below: (1) effect: hydrolyzing the &#x3b2;-1,3-bond of &#x3b2;-1,3-glucan; and (2) substrate specificity: decomposing at least paramylon. The &#x3b2;-1,3-glucanase additionally exhibits the properties indicated below: (3) decomposition activity: the ratio of paramylon decomposition activity with respect to laminarin decomposition activity is 20% or higher; (4) optimum pH: 3.7-7.0; and (5) optimum temperature: 30-70&#xb0; C.
