On the occurrence and significance of bacteria in living trees of Populus nigra L. Eleven strains of bacteria were isolated from sapwood and heartwood of living poplar trees ( Populus nigra L.) and identified mostly as Erwinia, Xanthomonas, Agrobacterium and Acinetobacter. Most of them were able to attack milled wood and the wood components pectin, hemicelluloses and holocellulose; α‐cellulose and lignin were not consumed. The capillary liquid in the xylem of poplar served as a nutrient for the isolated bacteria. The significance of these bacteria for wetwood formation is discussed.
