Functional classification of the identified proteins and regulation of their abundance.

aChanges in protein levels are reported as the ratio between the relative spot volume from L. acidophilus grown in the presence of rutin and L. acidophilus grown in control conditions (Vrutin/Vcontrol) for increased proteins and as the negative reciprocal values (-Vcontrol/Vrutin) for decreased proteins. Changes in protein levels >1.5 have been considered significant.bAverage fold change for proteins contained in more than one spot has been calculated considering the relative spot volume of all the spots containing the same protein and a fold change >1.5 has been considered significant.Functional classification of the identified proteins and regulation of their abundance.
