Fluorescent Pseudomonas species (P. aeruginosa, P. fluorescens, P. putida) were tested for the presence of glycosidase activities (alpha-D-glucosidase, beta-D-glucosidase, alpha-D-galactosidase, beta-D-galactosidase, beta-xylosidase, alpha-D-mannosidase, alpha-L-fucosidase, beta-L-fucosidase, beta-D-glucuronidase and N-acetyl-beta-D-glucosaminidase). Some of the investigated glycosidases were always absent, while N-acetyl-beta-D-glucosaminidase was constantly present in all strains; 3 glycosidase activities were observed in association or separately. Serotype O11 of P. aeruginosa was found to be homogeneous with respect to some of those enzymatic activities. Search for beta-D-galactosidase, alpha-D-glucosidase and beta-D-glucosidase may be of diagnostic value in epidemiologic studies of P. aeruginosa.
对荧光假单胞菌属物种（铜绿假单胞菌、荧光假单胞菌、恶臭假单胞菌）进行了糖苷酶活性（α-D-葡萄糖苷酶、β-D-葡萄糖苷酶、α-D-半乳糖苷酶、β-D-半乳糖苷酶、β-木糖苷酶、α-D-甘露糖苷酶、α-L-岩藻糖苷酶、β-L-岩藻糖苷酶、β-D-葡萄糖醛酸酶和N-乙酰-β-D-葡萄糖胺酶）检测。一些被研究的糖苷酶总是不存在，而N-乙酰-β-D-葡萄糖胺酶在所有菌株中均持续存在；观察到3种糖苷酶活性以联合或单独形式存在。发现铜绿假单胞菌O11血清型在其中一些酶活性方面具有同质性。对β-D-半乳糖苷酶、α-D-葡萄糖苷酶和β-D-葡萄糖苷酶的检测在铜绿假单胞菌的流行病学研究中可能具有诊断价值。
