Next day isolated colony was identified by gram staining and conventional biochemical tests without any automated instruments as per standard laboratory protocol [10]. Pseudomonas fluorescens. The worldwide emergence of multi-drug resistant bacterial strains is a growing concern, especially infections caused by Pseudomonas spp. Biofilm removal of Pseudomonas strains using hot water sanitation 75 water was more remarkable in the case of both Pseudomonas strains, which indicates a higher amount of glicocalix production in nutrient-poor medium (mineral water). MacCONKEY’S AGAR MacConkey’s agar is a differential plating medium used in the detection and isolation of all types of dysentery, typhoid and paratyphoid organisms. Pseudomonas fluorescens grows better in glucose-enriched LB media than in LB media alone Andrew Passer and Muhammad Khan Abstract We have demonstrated that the bacterium Pseudomonas fluorescens grows to a higher density in broth enriched with glucose than it does in only an amino acid broth. It has proved useful for identification of intestinal bacteria. aeruginosa. 8136 NAAS Rating: 3. Pseudomonas aeruginosa is the only gram-negative bacillus capable of pro-ducing the very distinctive water-soluble pigmentpyocyanin. Pseudomonal infections are increasingly resistant to certain antibiotics, and the organism may acquire resistance during therapy. This medium promotes fluorescein pigment production. Other key biochemical characteristics include oxidation of glucose but not. The received samples for culture and sensitivity test were inoculated in Blood agar and MacConkey agar respectively and kept overnight at 37°C in the incubator.
