Microbiological Expertise

With our team of specialists and the latest relevant tools in microbiology, our laboratory is able to offer comprehensive expertise for the identification and counting of microorganisms, from the grape to the bottled wine.

Our team (including doctors and technicians in microbiology, engineers, chemists and winemakers) is at your disposal to respond to all of your microbiological problems.

SARCO offers both classical techniques of microbiology and recent biological genetic methods as well as tools for the determination of contaminants coming from microorganism spoilages.

Microscopy	Microscopic observation Counting of viable microorganisms by epifluorescence
Counting of microorganisms by culture on selective medium	Mould Total yeasts non- Saccharomyces yeasts Brettanomyces yeasts Acetic bacteria Lactic acid bacteria Total flora Salmonella research E. coli Coliforms Clostridium perfingens Staphylocoques coagulases + Pseudomonas Total mesophilic flora
Specific detection of spoilage microorganisms by PCR	Brettanomyces bruxellensis (quantification) Zygosaccharomyces baillii (detection) Lactic acid bacteria strains that produce biogenic amines (quantification) Lactic acid bacteria strains with ropy (detection)
Specific detection of microorganisms by PCR	Torulaspora delbruecki (quantification) Saccharomyces cerevisiae Saccharomyces uvarum Oenococcus oeni
