The modifying effect of different Bacillus subtilis strains on permeability of pine (Pinus taeda) in two different culture media
One of the main reasons for low treatability of pine wood is pit aspiration during drying in free water domain or heartwood formation. In this research, for opening the aspirated pits in heartwood of loblolly Pine (Pinus taeda), biological incising modification method with bacteria was used and the...
