The C-390-based P. aeruginosa selective medium was reported to inhibit the growthofall organismstested except P. aeruginosa at 102 to 103 CFU per plate, although P. Nitrofurantoin level greatly affected % transmittance. Tumwater Wa Obituaries, A modified selective medium (modified Cetrimide Agar, mCA) consisting of 200 μg/mL benzalkonium chloride (BKC) was developed for the isolation of Pseudomonas aeruginosa from raw milk. A major disadvantage of culture method is time needed to produce results (Vasavada and White 1993). Analytical microbiology leverages a microbe’s unique biochemistry to aid in its identification. The function of the protein encoded by the PflQ2_2232 locus is unknown. Irgasan™is a trademark of Ciba-Geigy.
