Abstract
Twenty actinobacterial strains belong to the genus Pseudonocardia were screened for their ability to degrade poly (lactide) plastic. Pseudonocardia alni AS4.1531T was the only strain that decreased PLA film weight by more than 70% in eight days. This strain could degrade 35.8 mg out of 50 mg PLA films in liquid culture containing 0.1% (w/v) gelatin. In addition, Pseudonocardia alni AS4.1531T assimilated the major degradation product, lactic acid.
