摘要

正

The biodegradability of Aspergillus niger （A. niger）

Mucor （M-305） and Trichoderma（T-311） strains on regenerated cellulose films in media was investigated. The results showedthat T-311 strain isolated from soil adhered on the cellulose film fragments has strongerdegradation effect on the cellulose film than A. niger strain. The weights

molecular weightsand tensile strengths of the cellulose films in both shake culture and solid media decreasedwith incubation time

accompanied by producing CO

and saccharides. HPLC

IR and re-leased CO

analysis indicated that the biodegradation products of the regenerated cellulosefilms mainly contain oligosaccharides

cellobiose

glucose

arabinose

erythrose

glycerose

glycerol

ethanal

formaldehyde and organic acid

the end products were CO

and water.After a month

the films were completely decomposed by fungi in the media at 30℃.
