Comparison of PHA yield as a percentage of dry weight between LSBJ and RSC02 at 24 h and 48 h, utilizing either sodium butyrate (C4) or decanoic acid (C10). LSBJ saw insignificant changes in PHB production between 24 and 48 h, while RSC02 increased slightly from 8.2 to 12.3% of cell dry weight. PHD yield from LSBJ increased from 22.6 to 31.7% between 24 and 48 h, an increase of ~40%, while PHD yield from RSC02 increased from 37.2 to 45.0%, an increase of ~20%. Regardless of the time, RSC02 produced more polymer than LSBJ in all cases. All values are the averages of triplicate experiments plus or minus the standard deviation about those averages
