| Abstract | An enrichment technique led us to isolate 13 cyclo (Gly-Tyr)-assimilating bacteria, which had higher cyclo (Gly-Tyr)-hydrolyzing activity that the coryneform rod bacterium strain T-1-3-Y,previously isolated from soil. The cell-free extract of the strain Ol-L-2 prepared by ultrasonication in a buffer containing bovine serum albumin had cyclo (Gly-Tyr)-hydrolyzing activity while that of the strain T-1-3-Y showed no activity. GEMA (Glucosyloxyethyl methacrylate) polymer was found to be a more effective stabilizer for solubilizing cyclo (Gly-Tyr) hydrolase than bovine serum albumin.

| Abstract Alternative | 集積培養法を用いて新たに土壌よりcyclo(Gly-Tyr)資化性菌を分離し、その中から、従来の資化性菌より菌体当たりの活性の高い菌株を13株見いだした。これらの菌株を牛血清アルブミンを添加した緩衝液中に懸濁し、超音波破砕に供したところ、OI-L-2株由来の無細胞抽出液中にcyclo(Gly-Tyr)分解活性が検出された。この活性は安定化剤をアルブミンから配糖化合成高分子GEMAポリマーに代えることによりさらに安定に抽出された。
