title: Nitro derivatives from the Arctic ice bacterium Salegentibacter sp. isolate T436.
abstract: Twenty-five aromatic nitro, dinitro and trinitro compounds were isolated in low yields of less than 1 mg l(-1) from a Salegentibacter sp. strain T436 derived from Arctic pack ice. Their structures were elucidated by MS and NMR techniques. Seven of these compounds, namely, 2-hydroxy-3-(4'-hydroxy-3'-nitrophenyl)-propionic acid methyl ester (6), 2-chloro-3- (4'-hydroxy-3'-nitrophenyl)propionic acid methyl ester (7), 3-(4'-hydroxy-3',5'-dinitrophenyl)-propionic acid methyl ester (14), 4'-hydroxy-3',5'-dinitrophenylethylchloride (16), (4'-hydroxy-3',5'-dinitrophenyl)-2-chloropropionic acid methyl ester (17), N-acetyl-3',5'-dinitrotyramine (18) and 2,6-dinitro-4-(2'-nitroethenyl)phenol (19) are new, and five are reported in this study from a natural source for the first time.
