Practical application of immunofluorescence for the detection of bacterial contaminants during vinification
Abstract
This study presents a rapid and specific microscopie technique for detecting and identifying populations of lactic acid bacteria in musts, wines, and inoculum starter cultures. Through the use of fluorescent antibodies, this procedure can be performed in less than two hours, and it is effective with Leuconostoc, Pediococcus and Lactobacillus concentrations as small as 102 cells/ml. Implementation of this technique will assist winemakers in controlling malolactic fermentations and in preventing lactic acid bacterial spoilage.
