FIG 1.

Fatty acid and methyl ketone production in R. eutropha strains expressing ′tesA. Titers of fatty acids (extracted from the cell pellet and derivatized as FAME) and methyl ketones (accumulated in the decane overlay) are shown for two fructose-grown R. eutropha mutant strains expressing ′tesA (mutants with β-oxidation and/or phaCAB chromosomal deletions; Table 1). Asterisks indicate strains that were not induced with arabinose. Values are averages for at least three independent biological replicates, and error bars represent one standard deviation at 96 h postinduction.
