Fluorescence and bioluminescence analysis of sequential UV-biological degradation of p-cresol in water

The photolysis and Penicillium tardum H‐2 degradation of p‐cresol in water containing humic acids was investigated by fluorescence and bioluminescence methods. Humic acids extracted from peat (the Vasuygan bog, Tomsk region of Russia) induce the phototransformation of p‐cresol. The influence of humi...

Description
Summary:The photolysis and Penicillium tardum H‐2 degradation of p‐cresol in water containing humic acids was investigated by fluorescence and bioluminescence methods. Humic acids extracted from peat (the Vasuygan bog, Tomsk region of Russia) induce the phototransformation of p‐cresol. The influence of humic acids on the phototransformation of p‐cresol under different irradiation conditions was investigated. Comparison of the data on the KrCl* (λ = 222 nm) and XeCl* (λ = 308 nm) excilamps light showed that the most effective p‐cresol degradation was observed with mercury lamp irradiation in the presence of humic acids.
