Sabouraud Dextrose Agar Plate w/ Lecithin, Polysorbate 80 & β-Lactamase I (γ-irradiated) (Triple Pack)

This medium is recommended for cultivation of yeasts, moulds and aciduric microorganisms and for inactivation of β-lactam antibiotics. Lecithin and polysorbate 80 neutralizes quaternary ammonium compounds and parahydroxy benzoates. β lactamase enzyme breaks the β-lactam ring of antibiotic, deactivating the molecule's antibacterial properties thus enabling recovery of organisms from the environment of cleanrooms where production of antibiotics is carried out.
