Yeast-11
Flocculation

VIEW METHOD

Summary
This method measures flocculation of a yeast sample by the Helm assay, in which sedimentation of a yeast sample is observed in a calcium sulfate solution buffered at pH 4.5 to determine sedimentation volume and flocculation type, and by the absorbance method, in which flocculation is measured by absorbance after a settling reaction in a calcium sulfate solution buffered at pH 4.5.
