Compact Dry ETB is a simplified medium to determine number of Enterobacteriacae by the combination of selective agents and pH indicator.
Colonies grown on ETB plate are distinguished by red/purple color for Enterobacteriaceae.
Medium contains selective agent and pH indicator, glucose for detecting Glucose fermenting bacteria.
