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 potential...
متن کاملMitigating the pine wood nematode and its insect vectors in transported coniferous wood
The pine wood nematode ~ B ~ 1 ~ c 1 ~ 1 e xyloplzil~~s) (PWN) has been intercepted in pine chips. unceasoned lumber and packing-case wood. Likehise. PWN insect vectors, Molzochnmus spp., have been found in pallets, crates, and dunnage. As a result of these interceptions and the known consequences of the introduction of the PWN. many countries regulate the import of coniferous wood. Science-bas...
متن کاملSoft glassy rheology of supercooled molecular liquids.
We probe the mechanical response of two supercooled liquids, glycerol and ortho-terphenyl, by conducting rheological experiments at very weak stresses. We find a complex fluid behavior suggesting the gradual emergence of an extended, delicate solid-like network in both materials in the supercooled state-i.e., above the glass transition. This network stiffens as it ages, and very early in this p...
متن کاملInteractions affect hyphal growth and enzyme profiles in combinations of coniferous wood-decaying fungi of Agaricomycetes
Fomitopsis pinicola is a species of Polyporales frequently encountered in Nordic temperate and boreal forests. In nature, the fungus causes destructive brown rot in wood, colonizing tree trunks often occupied by other Basidiomycota species. We mimicked these species-species interactions by introducing F. pinicola to five white rot species, all common saprotrophs of Norway spruce. Hyphal interac...
متن کاملinvestigating the effect of wood particle size on the rheology and physical-mechanical properties of wood-polypropylene composite
the growing interest in using natural fibers as reinforcing agents of polymer-based composites is mainly due to their advantages such as lower cost, lower density, ease of preparation, lower energy requirements for processing, biodegradability, wide availability and relative non-abrasiveness over traditional reinforcing fibers such as glass and carbon. in this study, wood-plastic composite (wpc...
