Rapid determination of spoilage fungi.
Mixed cultures of viable spores of fungi of the Aspergillaceae were determined rapidly by gas-liquid chromatography of the methanol released from pectin by the enzyme pectinesterase. Results obtained in 19 h were comparable with plate counts taking 48 h. Attempts to count spoilage years using this method were not successful.
