Granulated selective culture medium for isolation and differentiation of Pseudomonas aeruginosa and Pseudomonas species in microbiological quality control testing of pharmaceutical, environmental and industrial samples.
Cetrimide agar, catalogue No. 105284, is a granulated microbiological culture medium supplied by MilliporeSigma / Merck under the GranuCult® prime quality designation. The medium is formulated with cetrimide (N-Cetyl-N,N,N-trimethyl ammonium bromide) as a selective agent to inhibit competing bacterial flora and facilitate the selective growth, isolation and differentiation of Pseudomonas aeruginosa and other Pseudomonas spp. Its formulation supports characteristic pigment production by P. aeruginosa, aiding in identification from mixed cultures. This product is intended for quality control and microbiological testing in pharmaceutical, environmental and related laboratory workflows.
Advantages
