Rosolic Acid, Powder, 1g

When used as a supplement in m-FC agar, rosolic acid helps suppress background microorganisms and non-target coliforms, improving recovery and differentiation of fecal coliforms at elevated incubation temperatures (44 - 45 °C). Typical fecal coliform colonies develop a blue coloration on m-FC agar containing rosolic acid, while non-target organisms generally appear gray to cream-colored.
