Title
(EN) METHOD FOR PROMOTING BACTERIAL CELL WALL DEGRADATION
(FR) PROCÉDÉ POUR FAVORISER LA DÉGRADATION DE PAROI CELLULAIRE BACTÉRIENNE
(JA) 細胞壁分解促進方法
Abstract
(EN)
To provide a method for promoting degradation of the cell wall of a bacterium. The method for promoting bacterial cell wall degradation is characterized by comprising treating the bacterium with N-acetyl muramidase in the presence of one or more kinds of saccharides selected from the group consisting of a monosaccharide that is aldopentose, L-aldohexose or ketohexose, a disaccharide, an oligosaccharide or a polysaccharide each comprising one or more kinds of the aforesaid monosaccharides as constituting saccharide(s) thereof and derivatives of the same.
(FR)
L'invention concerne un procédé pour favoriser la dégradation de la paroi cellulaire d'une bactérie. Le procédé pour favoriser la dégradation de paroi cellulaire bactérienne est caractérisé en ce qu'il comprend le traitement de la bactérie avec de la N-acétyl muramidase en présence d'un ou de plusieurs types de saccharides choisis dans le groupe constitué par un monosaccharide qui est un aldopentose, L-aldohexose ou cétohexose, un disaccharide, un oligosaccharide ou un polysaccharide comprenant chacun un ou plusieurs types des monosaccharides mentionnés ci-dessus comme étant un ou des saccharide(s) de celui-ci et des dérivés de celui-ci.
(JA)
細菌の細胞壁分解促進方法の提供。アルドペントース、L体のアルドヘキソース又はケトヘキソースである単糖、該単糖の1種以上を構成糖とする二糖、オリゴ糖及び多糖、並びにそれらの誘導体からなる群より選択される1種又は2種以上の糖の存在下で、N-アセチルムラミダーゼを細菌に作用させることを特徴とする、細胞壁分解促進方法。
