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

<p>^aChanges in protein levels are reported as the ratio between the relative spot volume from <i>L</i>. <i>acidophilus</i> grown in the presence of rutin and <i>L</i>. <i>acidophilus</i> 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.</p><p>^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.</p><p>Functional classification of the identified proteins and regulation of their abundance.
