Fig. 6. Influence of UV duration on the inactivation rate of microorganismsSimple PEF treatment reduced microbial load of the suspension, thereduction rate may vary depending on the type of organism and treatment duration( Fig. 7).Fig. 7. Influence of the durationof the pulsed electric field (PEF)over the inactivation ofmicroorganismsBetween the microbial load (expressed in CFU / ml) of the groups oforganisms (yeast, lactic acid bacteria and acetic bacteria), and the PEF treatmentduration were established 1st degree relations.Only regression equation parametersare different (Table 3.2).UV + PEF treatments combined (Table 3.3, Fig. 8) and PEF + UV (Table3.4, fig. 9) have been very effective in causing inactivation of nearly allmicroorganisms.311
