Title
Visible light and enzymatic induced synthesis of malic acid from pyruvic acid and HCO3- with the combination system of zinc chlorophyll derivative and malic enzyme in water media
Abstract

Visible light and enzymatic induced synthesis of malic acid from pyruvic acid and HCO3- with malic enzyme (ME) and NADP+ photoreduction by the visible light photosensitization of chlorophyll derivative, zinc chlorin-e6 (Zn Chl-e6) in the presence of NADH as an electron-donating reagent was investigated. When the sample solution containing NADH, Zn Chl-e6, methylviologen (MV2+), pyruvic acid, NaHCO3, NADP+, ferredoxine-NADP+-reductase (FNR) and ME was irradiated with visible light (>390 nm), malic acid was produced. The produced malic acid was 0.65 mmol dm−3 after 3 h visible light irradiation.
