Granulated Tryptose sulfite cycloserine (TSC) agar base for selective isolation and enumeration of Clostridium spp. in food, water and environmental microbiology according to ISO 15213 and related standards.
Tryptose sulfite cycloserine agar (base), catalogue No. 111972, is a granular microbiological culture medium supplied by MilliporeSigma / Merck under the GranuCult® prime quality segment. It is specifically formulated for the selective isolation, differentiation and enumeration of sulfite-reducing Clostridium spp., including Clostridium perfringens, from food, feed, water and environmental samples. The medium supports the growth of target Clostridia and suppresses non-target flora, facilitating accurate determination of microbial contamination in quality control laboratories. It is compliant with ISO 15213, ISO 14189, AOAC, APHA and FDA-BAM analytical standards.
