This doc discusses methods for standardizing antibiotics. It notes there are 3 crucial points for standardization: following FDA polices, referring to FDA methods for person antibiotics, and measuring inhibition of microbial development. Two common assay methods are explained: the cylinder-plate method which measures zones of inhibition, along with the turbidimetric method which actions prevention of microbial advancement.

This technological innovation detects microbial progress by tracking CO2 production for the duration of incubation. Microorganisms because they increase, will metabolize the substrate present in the lifestyle media and generate CO2.
