Abstract

In Japan, solid-phase fungal fermentation system using the industrial fungi Aspergillus oryzae have been extensively used for producing fermented foods such as sake and soy sauce; the annual production volume of the products is over one million ton per year. These efficient enzymatic hydrolyzing systems are expected to be applicable to biological recycling of biodegradable plastics. We found that A oryzae can degrade polybutylene succinate-coadipate (PBSA) by combinations with an esterase (cutinase) CutL1 and novel biosurfactants, RolA and HsbA that are attached to the surface of PBSA and then recruit CutL1 to the surface.
