A sterility testing medium where clarity of the medium is required, Fluid Thioglycollate Medium w/K Agar is suitable for isolation of A. acidoterrestris spores from fruit juices. K Agar is a native form that exhibits exceptional clarity in gel form, allowing for easier visual detection of bacterial growth. Dextrose, casitone, cystine, and yeast extract provide the growth factors necessary for bacterial replication. Sodium provides essential ions. The reducing agents sodium thioglycollate and cystine lower the redox potential of the medium, thereby supporting anaerobiosis. Sodium thioglycollate also prevents accumulation of peroxides which are lethal to some microorganisms. Resazurin serves as redox indicator.||Appearance: |Light tan, homogeneous free flowing powder||Solubility: |Amber/Yellow (top 10% light pink to medium red), clear ||pH: |As Reported
