For basic function agar media only, Growth Promotion Test shall be completed by inoculation method with exemption of inhibitory and indicative test.

Degradation of lactose to acid is indicated through the pH indicator neutral red, which variations its coloration to pink, and by precipitation of bile acids.

The inoculated medium is then incubated below acceptable situations, plus the growth of microorganisms is monitored more than a specified stretch of time.
