研究了7种土壤丝状真菌对壳聚糖-结冷胶（CGF）和聚赖氨酸-结冷胶（LGF）两种聚离子复合物（PIC）纤维的降解作用。所有的纯系土壤丝状真菌，曲霉菌，青霉菌，桔黄青霉菌，毛霉属，根霉属，弯孢菌属，和枝孢霉（Cladosporium sp.）在两种纤维材料上生长。对生物降解过程的显微镜观察显示，干酪根皮杆菌在CGF和LGF上生长，沿着纤维基质的塌陷。在生化需氧量（BOD）试验中，干酪伪杆菌和弯孢菌对LGF的降解率超过97%，而A.平均为59%。这些结果为PIC纤维作为环境生物降解材料的应用提供了线索。
The degradation of two kinds of polyion complex (PIC) fibers, chitosan-gellan (CGF), and poly(L-lysine)-gellan (LGF) fibers, by seven species of soil filamentous fungi has been investigated. All of the pure-line soil filamentous fungi, Aspergillus oryzae, Penicillium caseicolum, P. citrinum, Mucor sp., Rhizopus sp., Curvularia sp., and Cladosporium sp. grew on the two fiber materials. Microscopic observation of the biodegradation processes revealed that P. caseicolum on the CGF and LGF grew, along with the accompanying collapse of the fiber matrices. In the biochemical oxygen-demand (BOD) test, the biodegradation of the LGF by P. caseicolum and Curvularia sp. exceeded 97% carbon dioxide generation and the biodegradation of the CGF by A. oryzae was 59%. These results might offer some clues to the applications of the PIC fibers as environmentally biodegradable materials.
