Characteristics of bacterial strains inhabiting the wood of coniferous trees.

The presented studies embraced samples of wood chips from coniferous trees which contained layers of duramen, alburnum and bark. Microbiological analysis involved qualitative and quantitative determination of bacterial flora inhabiting the studied wood material. The wood chips were found to contain primarily species belonging to the genera Bacillus and Pseudomonas. The presence of the potentially pathogenic species Bacillus cereus 1, Sphingomonas paucimobilis, Aeromonas salmonicida and Chryseomonas luteola was also demonstrated.
