Miyatani R, Amao Y: Lactic acid production with lactate dehydrogenase using the visible light sensitization of zinc porphyrin. Photochem Photobiol Sci. 2004 Jul;3(7):681-3. Epub 2004 May 20.
Lactic acid production with L-lactate dehydrogenase from Pig heart (LDH) and reduced methyl viologen produced by the visible light photosensitization of zinc tetrakis (4-methylpyridyl) porphyrin (ZnTMPyP) was investigated. When the sample solution containing triethanolamine as an electron-donating reagent, ZnTMPyP, methyl viologen as an electron carrier, pyruvic acid and LDH in potassium phosphate buffer (pH 7) was irradiated, lactic acid production was observed. After 240 min irradiation, the amount of lactic acid production and the yield of pyruvic acid to lactic acid were estimated to be 0.17 mmol dm (-3) and 17.0%, respectively. |
