^aThere were no significant JS666 hits for samples 7 to 9, 11, 14, and 15.

^bProteins upregulated by both reference substrates are indicated by bold type. Annotations were derived from the DOE Joint Genome Institute Integrated Microbial Genomes database.

^cThe protein score (or Mowse score) is −10 × log (P), where P is the probability that the observed match is a random event.

^dNumber of peptides with an expectation value of <0.01 as identified using LC-MS/MS. The expectation value corresponds to the number of matches that are expected to occur by chance alone.
