| Method |
Primary source abstract: "[Investigators] used (13)C nuclear magnetic resonance ((13)C-NMR) to demonstrate that P. aeruginosa maintains both choline and glycine betaine pools under a variety of conditions, in contrast to the transient glycine betaine pool reported for most bacteria. [They] were able to experimentally manipulate the choline and glycine betaine pools by overexpression of the cognate catabolic genes." |
| Comments |
P.2117 right column 2nd paragraph: "P. aeruginosa maintains intracellular pools of choline and GB (>12 ng/mg [dry weight] and >45 ng/mg [dry weight], respectively) under conditions of exposure to choline regardless of the osmotic conditions (primary source), in contrast to what happens in the enteric bacteria studied to date." |
