^aThe data represent mean values and standard deviations derived from three independent microarray slides, with two replicates on each slide.

^bgi151388, naphthalene dioxygenase large subunit; gi151385, naphthalene dioxygenase (reductase subunit); gi5070351, cis-1,2-dihydro-1,2-dihydroxynaphthalene dehydrogenase; gi5824143, alkane 1-monooxygenase; gi5824146, aldehyde dehydrogenase; gi5824147, alcohol dehydrogenase.

^cSNRs for probes of identities from 76 to 84% are all <0.3.

^dNumbers for threshold points above which SNR is >3 are in boldface.
