Effects of 10-hydroxydecanoic acid on the oxidation of alkanes. The substrates were as follows: a 4 g/L decane and 1 g/L 10-HDA; b 4 g/L decane. Error bars represent standard deviation of two independent runs. Symbols:
: optical density, A600;
: sebacic acid concentration;
: decane concentration;
: 10-hydroxydecanoic acid concentration;
: decanoic acid concentration
