Thermo Scientific™ STAA Agar Base (Dehydrated)

Description

• Isolate Brochotrix thermosphacta from food samples with Thermo Scientific™ Oxoid™ STAA Agar Base (Dehydrated)
• STAA Medium (STAA Agar Base + STAA Selective Supplement SR0151) is based on the formulation described by Gardner 1 and is recommended for microbiological examination of meat and meat products in the ISO Standard 13722:1996
• Brochotrix thermosphacta is a Gram-positive rod and constitutes a significant proportion of the spoilage flora of meat and meat products
• Although Brochothrix thermosphacta is not considered to be pathogenic, it is an economically important meat-spoilage organism because it grows in a wide variety of meats and meat products and produces malodorous metabolic end products which make affected meat unpalatable 3
• STAA Medium is made selective by the inclusion of streptomycin sulphate, thallous acetate and actidione (cycloheximide)
• STA Medium is modified from the original formulation by removal of the toxic selective agent cycloheximide as recommended by the NMKL
• According to this method the medium is applicable for meat, meat products and some fish products
• Streptomycin sulphate inhibits some Gram-positive organisms and most Gram-negatives at higher concentrations, while Brochothrix thermosphacta remains resistant
• Thallous acetate inhibits most yeasts as well as many aerobic and facultatively anaerobic bacteria
• The incorporation of cycloheximide serves to further inhibit yeasts and filamentous fungi
