Universal Beer Agar
Universal Beer Agar (UBA Medium) is used for cultivating microorganisms of significance in the brewing industry.
Principles
Yeast extract is a source of trace elements, vitamins and amino acids. Peptonized milk contains lactose as an energy source. Tomato juice is a source of carbon, protein and nutrients. Dextrose provides additional carbon. Dipotassium and monopotassium phosphates provide buffering capability. Magnesium sulfate, ferrous sulfate and manganese sulfate are sources of ions that stimulate metabolism. Sodium chloride provides essential ions. Agar is the solidifying agent.
Universal Beer Agar (UBA) is the industry-standard culture medium for detecting wild yeasts and spoilage organisms in beer production. Critical for brewery quality control. Formulation includes yeast extract, peptized milk, tomato juice, dextrose, phosphates, and mineral sulfates for optimal microbial metabolism. Available from Alpha Biosciences and Difco in 500g and 2kg sizes. One 500g container yields approximately 10-16 liters of prepared medium.
