School of Life Science and Engineering, Southwest University of Science and Technology, Key Laboratory of Waste Solid Treatment and Resource Recycle of Ministry of Education, School of Environment and Resource, Southwest University of Science and Technology, Mianyang 621010, Sichuan Province, China[Objective] To explore the effect of photoelectron and photogenerated hole on the metabolites of Alcaligenes faecalis. [Methods] We compared different effect of photoelectron and photogenerated hole on metabolism of Alcaligenes faecalis through the Three-dimensional fluorescence spectroscopy by adding the hole scavenger and electron capturer. [Results] Under light, the hole scavenger group obviously produced 4 to 5 times higher humus-like substances and intensity of NADH fluorescence peaks than the electron capturer group, while the Three-dimensional fluorescence spectra did not show visible change among the experimental sets under dark. In contrast, the electron capturer group under light shows stronger fluorescence peak than under dark. [Conclusion] This is the first report that the photoelectron will promote the Alcaligenes faecalis to produce humus substances and more energy. The photogenerated hole will promote the Alcaligenes faecalis to produce protein.
