• Phospholipase D (PLD)-mediated transphosphatidylation of phosphatidylcholine (PC) in a biphasic system was limited by the hydrolysis reaction. A biphasic system can produce a large amount of water. To solve this problem, a microaqueous water-immiscible organic solvent was used for the first time in the bioconversion of phosphatidylserine (PS). The transphosphatidylation among 40 µmol PC, 800 µmol L-serine, and 0.17 U/mL PLD in 2.133 mL of butyl acetate with 6.25% water (V/V) was conducted at a trans-phosphatidylation rate of 88% (mol/mol), and no hydrolytic reaction was observed. Compared to commonly used biphasic systems, this system shows a similar transphosphatidylation rate, whereas the undesirable hydrolysis of phospholipids was completely suppressed.
