微生物のベンツオイルーアミノ酸に対する水解能について

抄録

1) Two non-pathogenic soil bacteria, strains “KT1” and “KT3, ” were found to have a property of hydrolyzing hippuric acid, benzoyl-DL-α-aminobutyric acid and benzoyl-DL-phenylalanine.
2) A stock laboratory strain of Staphylococcus aureus Terashima and a strain of Staphylococcus isolated from bubo were both able to hydrolyze hippuric acid and benzoyl-DL-α-aminobutyric acid but not benzoyl-DL-phenylalanine.
3) From the experiments with hippuric acid and benzoyl-DL-phenylalanine, it may at least be said that Escherichia coli and Proteus OX 19 are quite inactive.
4) On the other hand, two strains of Penicillium, “NRRL 1978 B₂” and “176 Yabuta, ” are also able to liberate benzoic acid from either of the above-mentioned N-benzoylated amino acids.
