High-molecular-weight amylase activities from bacteria degrading starch-plastic films.
Amylases having unusually high molecular weights (M(r), >150,000) were found in culture supernatants of an environmentally derived microbial mixed culture selected for its ability to utilize starch-containing plastic films as sole carbon sources. The mixed culture produced amylases active at pHs 5.5 and 8.0.
