Sterile Sterile ready-to-use culture media plates for microbiological analysis. Diameter 90 mm Surface 63,6 cm 2 Ready-to-use and sterile Easy to use, reliable detection and simple evaluation Well applicable for microbiological analysis of samples With detailed instructions for use ROTI ® Plate90 are prepared culture media plates with a diameter of 90 mm. They are thus adapted to the size of membrane filters for assaying of low-germ fluids by membrane filtration method. They are also applicable for the microbiological analysis of samples in general. The germs of expected low-germ liquid samples are concentrated by membrane filtration. Afterwards, the membrane is placed on top of the medium and incubated. Using a membrane with a grid helps counting the resulting colonies. Our products are tested and approved exclusively for research and development. Samples which are expected to have a higher microbiological burden are prepared in a serial dilution. Afterwards, every dilution step is plated and incubated. The number of grown colonies is noted as result. ROTI ® Plate90 MRS ISO 11133, ready-to-use, sterile, for microbiology MRS Agar was developed by deMan, Rogosa and Sharpe to grow luxuriantly all strains of Lactobacilli especially the fastidious, slower-growing types such as L. brevis and L. fermenti . The medium is apt for the growth of lactic acid bacteria, including Lactobacillus , Streptococcus , Pediococcus and Leuconostoc . Ammonium citrate at a low pH inhibits most microorganisms, including other Streptococci and molds. It allows for the growth of Lactobacillus , but limits swarming in general.
