Characterization of poly(L-lactide)-degrading enzyme produced by thermophilic filamentous bacteria Laceyella sacchari LP175.

Eleven strains of poly(L-lactide) (PLLA)-degrading thermophilic bacteria were isolated from forest soils and selected based on clear zone formation on an emulsified PLLA agar plate at 50°C. Among the isolates, strain LP175 showed the highest PLLA-degrading ability. It was closely related to Laceyella sacchari, with 99.
