摘要：

The Gram-negative bacterial strain HKI 0380 was isolated from biofilms located on palaeolithic rock paintings in the Cave of Bats in Zuheros, southern Spain. It was identified as the phytopathogenic Erwinia persicina and attracted attention due to the production of considerable quantities of slime. The acidic exopolysaccharide produced by the E persicina was studied after O-deacylation by sugar and methylation analyses, along with H-1 and C-13 NMR spectroscopy. The following structure of the branched pentasaccharide repeating unit of the O-deacylated exopolysaccharide was established: [GRAPHICS] (c) 2005 Elsevier Ltd. All rights reserved.
