Siebel/Döhler Lee's Multi Differential Agar (LMDA) is used for the detection, selection and enumeration of bacteria commonly found in beer and breweries. Also known as Schwarz Differential Agar (SDA), this medium contains several reagents which aid in the identification of bacterial colonies, including a color indicator for acid production. The selectivity of this medium can be further enhanced by the addition of a yeast inhibitor and/or by anaerobic incubation. The Siebel/Döhler LMDA is an ideal medium for the detection of the following beer spoilage organisms:

• Lactobacillus spp.
• Pediococcus spp.
• Acetic acid bacteria
• Lactic acid bacteria
