Résumé :

The aim of this work was to estimate the biodegradation of a poly(lactic acid) polymeric material by the actinomycetes Kibdelosporangium aridum using a vermiculite based inert solid medium which could simulate compost medium and enable us to achieve complete carbon balances. The mineralisation rate at the end of the test was compared to those obtained for two basal media. It was shown that cumulative mineralisation after 45 days of degradation was greater (70%) in vermiculite with a basal medium containing gelatin than in vermiculite with a basal medium containing glucose (20%).
