Type: article
Abstract: Asaia bogorensis is a Gram-negative bacterium isolated from flowers and fruits growing in tropical climate, reproductive system of mosquitoes, and rarely from immunocompromised patients. In Europe, A. bogorensis is responsible for the contamination of flavoured mineral waters. One of the important surface antigen and an element of the bacterial biofilm is lipopolysaccharide (LPS, endotoxin). To date, no data on A. bogorensis LPS structure has been reported. Chemical analysis and 1 H, 13 C nuclear magnetic resonance spectroscopy revealed the novel structure of the O-specific polysaccharide of A. bogorensi s ATCC BAA-21 LPS. It was concluded that the repeating unit of the O-antigen is a branched trisaccharide with the following structure: →6)-α- d -Glc p -(1→2)-[β- d -Glc p -(1→3)]-α- l -Rha p -(1→ . • The O-specific polysaccharide was isolated from Asaia bogorensis ATCC BAA-21 LPS • Chemical analysis and 1 H, 13 C NMR revealed the novel structure of the O-antigen • The repeating unit is a branched trisaccharide consisting of Glc and Rha
