Polypropylene carbonate-polyvalerolactone(PPC-PVL) and polyvalerolactone (PVL) produced from exhausted carbon dioxide were degraded by Stenotrophomonas maltophilia separated from soils of waste landfill. The biodegradation was confirmed by FTIR spectrum. PPC-PVL and PVL were degraded $6.6\%,\;12\%$ respectively, at 28 days of pure Stenotrophomonas maltophilia culture.
