2.5. Screening tests
Green or yellow colony color was registered in TCBS media. For pigmentation, Gram, oxidase and catalase tests, each strain was analyzed from fresh cultures (18–24 h) seeded onto ZoBell agar media. Fifteen Gram-positive cocci,Ž . thirty-seven Gram-positive coccoid bodies and three Gram-negative rods were selected after these tests for further taxonomic analysis. To those 52 strains, their oxidative– fermentative metabolism was evaluated onto the O–F glucose media (Difco) supplemented with 2.5% NaCl. For cocci strains, we evaluate their capacity to grow at 15% NaCl onto T1N1 15 agar media Food and Drug Administration in order to separate the genus Staphylococcus and Micrococcus according to the Bergey’s manual
