硝酸盐还原试验

B反应、无机N源利用、柠檬酸盐利用呈阳性，硝酸盐还原试验大多呈阳性；

B reaction , inorganic nitrogen sources utilization and citrate utilization , the results were positive . Nitrate reduction experiment presented positive largely .

不利用糖类，不能在6.5%NaCl培养基中生长，尿素酶和硝酸盐还原试验均呈阳性，能凝集豚鼠和其他动物红血球。

Tests of the growing in 6 5 % NaCl medium and utilization of sugar were negative , whereas the nitrite reduction and urease were positive .

根据真菌培养的形态学特征和糖发酵、糖同化及硝酸盐还原试验，分离鉴定出镰刀菌属14例，念珠菌属14例，曲霉菌属9例，其他5例。

Following procedures in morphology , sugar fermentation , sugar assimilation and nitrate reduction tests were used to isolate and identify 14 cases of Fusarium , 14 cases of Candida , 9 cases of Aspergillus and 5 other cases .

从上述标准法未检出而本法判定为阳性的样品培养液中，分离可疑菌，经乳糖发酵、氧化酶和硝酸盐还原试验以及API20E鉴定，证明95.1%为大肠菌群。

After the cultures of the higher suspected parts were tested again with the lactose fermentation , and oxidase and reducing nitrate test together with the ApI-20E test . The results showed that the coliforms percentage tested are 95.1 % .

方法：对临床分离的85株棒状杆菌首选葡萄糖OF和硝酸盐还原两个试验将该属细菌初步分为4组，再用API方法鉴定到种。

Methods : 85 strains of Corynebacterium spp from clinical specimens were divided into 4 groups by the glucose fermentation test and the nitrate reduced test .
