Growth promotion testing of lifestyle media is a crucial Element of microbiological testing in assistance of pharmaceutical high-quality
Making use of aseptic approaches, inoculate the microbial strains onto the geared up society media. Stick to the Guidance provided in the SOP to be sure proper managing and distribution of the strains. Listen to the precise portions and places for inoculation as laid out in the SOP.
