The reported data are averages of at least two samples. The values in brackets are the deviations of the measured values from the mean.
Jatropha whole seed fermentable sugar values are relative to weight of jatropha whole seed.
Jatropha shell fermentable sugar values are relative to weight of jatropha shell.
