  • For the production of benzoylformic acid from DL-phenylglycine, 8 strains of bacteria capable of producing benzoylformic acid were isolated from soil. Among them, the strain YH-001 showed the highest activity for production of benzoylformic acid, and was partially identified as a Bacillus sp. For the production of benzoylformic acid, a reaction mixture and reaction conditions were optimized as follows: the reaction mixture contained 2 g of DL-phenylglycine and 50 g of wet cells in 1 l of 50 mM potassium phosphate buffer (pH 8.0) and the reaction was carried out at 40$circ$C with shaking. After 6 hr incubation, 1.01 g/l of benzoylformic acid was produced which coffesponded to a conversion yield of 50.5%.

  • 페닐아세트산을 이황화탄소와 사염화탄소 용매에서 광염소화시켜 $43{\%}$ 수득률로 ${\alpha}$-클로로페닐아세트산을 얻었다. 여기에 암모니아를 가하여 가열해 주었더니 $16\sim27{\%}$수득률로 페닐글리신이 합성되었다. 또한 글리신유도체에 광페닐화 반응을 아세톤, 벤조페논 증감제와 benzoylperoxide를 써서 시도하였다.
