SOYABEAN CASEIN DIGEST AGAR PLATE W/ b – LACTAMASE (g – irradiated)

Soyabean Casein Digest Agar Plate with β-Lactamase is a general-purpose culture medium recommended for the cultivation and enumeration of a wide variety of microorganisms and for the inactivation of β-lactam antibiotics. The medium is prepared in accordance with the harmonized microbial limit testing methodologies and is suitable for pharmaceutical applications. It is used for the detection and enumeration of microorganisms present on surfaces of sanitary importance and for environmental monitoring of clean rooms, particularly facilities involved in the production of cephalosporins. The ready-to-use plates are gamma irradiated within their packaging material to reduce the microbial load potentially present on the medium, dishes and packaging materials.
Tryptone and soya peptone provide nitrogenous compounds and other essential nutrients required for microbial replication. The addition of β-lactamase helps inactivate β-lactam antibiotics, reducing their antibacterial activity and enabling the recovery of resistant microorganisms present in clean room environments where antibiotic production takes place. The γ-irradiated ready-to-use plate format helps reduce the microbial load potentially present on the medium, dishes and packaging materials.
It is intended for pharmaceutical samples and can be incorporated into routine environmental monitoring and microbiological testing procedures where recovery of microorganisms in the presence of β-lactam residues is required.

Used for microbial cultivation and enumeration, with β-lactamase enabling recovery of microorganisms in environments containing β-lactam antibiotic residues.
