Characterization and Bioremediation of Birch Condensate
Keywords:Birch (<i>Betula papyrifera</i> Marsh), condensate, extractives, fungi treatment, <i>Phanerochaete chrysosporium</i>, GC-MS, FAB-MS, lipids, triglycerides
AbstractBirch (Betula papyrifera Marsh) condensate collected from a veneer plant in Michigan was analyzed for its major chemical constituents. This condensate contained carbohydrates and lipids. In the lipid fractions, triglycerides were the most abundant component (35-40%), followed by phenolic compounds (30%) and waxes (25-30%). Gas Chromatography-Mass Spectrometry (GC-MS) and Fast Atom Bombardment (FAB) MS were used to identify 14 lipid compounds. A white rot fungus, Phanerochaete chrysosporium [Burdsall-lombard, 5176, HHB-6251], was tested as a means for the bio-remediation of the condensate. P. chrysosporium reduced the total organic content (TOC) of the condensate from 350 ppm to 22 ppm and the color intensity from 0.614 to 0.355 absorbance units, after 2 weeks incubation in a liquid medium containing yeast and peptonc at pH 5.
