Specific biochemical tests such as gelatin liquefaction, production of levan, catalase test, oxidase test, arginine hydrolysis, indole production, phosphorous solubilization and growth at 4 and 41[degrees]C were conducted for identification of P.
levan formation, arginine hydroysis, indole production, phosphorous solubilization, gelatin liquefaction, oxidase test and catalase test (Table 3) which confirmed the identification of the selected isolates (I-7, I-15, I-18, I-23, I-24 and I-25) to be P.
Micrococci were identified by morphology, colony charecters and oxidase test
Biochemical activities of the isolated bacteria were analyzed by different biochemical tests such as amylase production, cellulase production, degradation of pectin, hydrolysis of gelatin, casein hydrolysis, urease test, hydrogen sulfide production, carbohydrate catabolism, IMVic tests, citrate utilization, catalaste test and oxidase test.
All the seven isolates were positive for oxidase test.

On the basis of growth on McConkey agar media, oxidase test
and oxidative-fermentative glucose tests the strains were grouped according to Weaver-Hollis scheme.
GPC were identified by catalase, coagulase, and modified oxidase tests
Representatives of each colony type were streaked for isolation on petri dishes containing tryptic soy agar (TSA) in order to perform oxidase tests
Several studies have examined the validity of blue food dye, gastric residual volumes, and glucose oxidase tests
as markers of pulmonary aspiration (Lukan et al.
