^aSee Fig. S2 in the supplemental material for the GC-MS profiles of metabolites.

^bMW, molecular weight.

^cNumbers are m/z values.

^dIdentification of metabolites was performed using a standard NIST traceable MS database, with TMS-derivatized alcohols downloaded from NIST standard reference database number 69 (available at http://webbook.nist.gov/chemistry/).

^e—, not applicable.

^fND, not detected.
