Phylogenetic Affiliation of Soil Bacteria That Degrade Aliphatic Polyesters Available Commercially as Biodegradable Plastics

摘要

Thirty-nine morphologically different soil bacteria capable of degrading poly(β-hydroxyalkanoate), poly(?-caprolactone), poly(hexamethylene carbonate), or poly(tetramethylene succinate) were isolated. Their phylogenetic positions were determined by 16S ribosomal DNA sequencing, and all of them fell into the classesFirmicutes and Proteobacteria. Determinations of substrate utilization revealed characteristic patterns of substrate specificities.
