First use of fractionation procedure and PARAFAC analysis to study IOM of E. coli. Released IOM decelerated the inactivation rate during photocatalytic inactivation. Four components were found in EEM-PARAFAC analysis. Toxicity occurred during inactivation then decreased with prolonged reaction time. Toxicity was found to positively correlate with one EEM-PARAFAC components.
