Abstract
A method for manufacturing an acetic acid bacterium culture and the acid bacterium culture, the acid bacterium culture contains PS1 (Glc:Gal:Man:GlcA=6.0:5.0 to 6.5:0.05 to 0.4:0.05 to 0.4) and/or PS2 (Glc:Rha:Man:GlcA=4.0:1.5 to 2.5:0.05 to 0.4:0.05 to 0.4) which are/is water-soluble polysaccharide(s). The method includes a fermentation step S1: a step of culturing acetic acid bacteria belonging to the genus Kozakia to give a first culture containing PS1, or culturing acetic acid bacteria belonging to the genus Komagataeibacter to give a first culture containing PS2, or culturing acetic acid bacteria belonging to the genus Kozakia and acetic acid bacteria belonging to the genus Komagataeibacter to give a first culture containing PS1 and PS2.
