Abstract

Ribotyping of brewery contaminants was carried out by automated ribotyping with the restriction enzymes EcoRI, PvuII and PstI. A database was created mainly including fingerprints of Lactobacillus spp., Pediococcus spp., Pectinatus spp., Megasphaera cerevisiae and Obesumbacterium proteus, but also of other lactic acid bacteria, enterobacteria, acetic acid bacteria, clostridia and pseudomonads. The most important property of ribotyping to characterize strains below species level, has been successfully applied in tracing of contamination routes and in detection of troublesome "house types" in industrial processes. The database created is extremely useful for reliable and rapid identification of bacteria isolated from brewing and malting industry.
