title: Isolation of an Acremonium sp. capable of liquefying cross-linked poly(gamma-glutamic acid) hydrogels and the fungal enzyme involved in the disruption of gamma-ray irradiation-mediated cross-linking.
abstract: A microorganism capable of liquefying cross-linked poly(gamma-glutamic acid) (C-L PGA) was isolated and identified to be an Acremonium sp. The fungus produced an enzyme that can disrupt the cross-linkages of C-L PGA generated by gamma-ray irradiation. The enzyme can also liquefy C-L PGA prepared by chemical cross-linkage, suggesting the involvement of ester bonds in the gamma-ray irradiation-mediated cross-linking of PGA.
