Structural elucidation of a novel phosphoglycolipid isolated from six species of Halomonas
The structure of a new phosphoglycolipid from the halophilic Gram-negative bacteria Halomonas elongata ATCC 33173T, Halomonas eurihalina ATCC 49336T, Halomonas almeriensis CECT 7050T, strain Sharm (AM238662), Halomonas halophila DSM 4770T, and Halomonas salina ATCC 49509T was elucidated by NMR and m...
