Characterization of the S-Layer Glycoproteins of Two Lactobacilli
Surface layer (S-layer) glycoproteins have been described on many archaeobacteria. Among eubacteria their presence has only been reported for the Bacillaceae (for a review see Messner and Sleytr, 1992). Lactic bacteria often produce extracellular polymers such as slimes and capsules (for example those described by Nakajima et al., 1990 and Racine et al., 1991). Most of these polymers are polysaccharides but a few reports claim the presence of glycoproteins in lactic streptococci (Macura and Townsley, 1984) and lactobacilli (Garcia-Garibay and Marshall, 1991). These observations have encouraged us to extend our survey on glycosylated S-layer proteins to lactobacilli.
