The doc outlines numerous techniques for microbial limit testing of pharmaceutical products and raw materials, which includes full aerobic microbial rely testing employing membrane filtration, plate rely, and serial dilution techniques.
The oxidase test detects the enzyme cytochrome c oxidase to tell apart in between oxidase-beneficial and -adverse microbes. The gelatin hydrolysis test identifies bacteria that will deliver the protease gelatinase to liquefy gelatin. The starch hydrolysis test detects germs that deliver the amylase enzyme to break down starch.
