The procedures and media explained from the EP had been made use of. The viable aerobic mesophile microorganisms rely was executed by plating one ml of decimal dilutions on casein soy agar. Plates had been incubated at 30 °C for 5 times. The results are displayed as colony forming models per gram of sample (CFU/g). The molds and yeast depend was carried out by plating one ml of decimal dilutions on Sabouraud dextrose agar.
Execute a unfavorable Manage as test sample, using the picked pre incubated diluent instead of the test preparation.
The product or service complies with the test, if colonies are not current or If your confirmatory identification tests are adverse.
