Abstract

The biodegradability of a nanofiber film (a nanofiber structure) produced in example 1 by microorganisms or the like when the nanofiber film is allowed to leave in soil is examined. Fig. 4 (a) shows a photograph of the nanofiber film immediately after the nanofiber film is placed in soil. Fig. 4(b) shows a photograph of the nanofiber film (a) that is allowed to leave as it for 12 days. As is obvious from the comparison between these photographs, a polyhydroxyalkanoic acid nanofiber film can be degraded in soil remarkably rapidly. Therefore, PHA can be produced from a plant- derived resource occurring in nature, can be degraded by microorganisms in soil to return to nature, and can be used as a resource material which can overcome the disadvantages of the conventional PP non-woven fabrics (e.g., the generation of CO2 upon incineration) and which can be used permanently, thereby enabling the production of a novel non-woven fabric. (Fig. 4(A) & Fig.4(B))
