In this work, we describe the construction of a synthetic metabolic pathway enabling direct biosynthesis of 1,3-propanediol (PDO) from glucose via the Krebs cycle intermediate malate. This non-natural pathway extends a previously published synthetic pathway for the synthesis of (L)-2,4-dihydroxybutyrate

Phenyllactic acid (PLA) is a novel antimicrobial compound. A novel NADH-dependent d-lactate dehydrogenase (d-LDH), named as LF-d-LDH0653, with high phenylpyruvate (PPA) reducing activity was isolated from Lactobacillus fermentum JN248. Its optimum pH and temperature were 8.0 and 50 °C, respectively.
