Abstract Various microorganisms were screened for their ability to degrade poly(tetramethylene succinate)‐co‐(tetramethylene adipate) (PBSA). Strain BS‐3, which was newly isolated from a soil sample, was selected as the best strain. From taxonomical studies, the strain was tentatively ascribed to belong to the genus Acidovorax , most probably to the species A. delafieldii . Strain BS‐3 could degrade both solid and emulsified PBSA, and also emulsified poly(tetramethylene succinate). During the degradation, a lipase activity was observed in the culture broth. This lipase activity was induced more strongly by PBSA than by tributyrin or triolein which are typical substrates of lipase. These observations strongly suggest that this lipase was involved in the PBSA biodegradation in strain BS‐3.
