Single-step production of polyhydroxybutyrate from starch by using alpha-amylase cell-surface displaying system of Corynebacterium glutamicum
Direct polyhydroxybutyrate (PHB) production from starch was for the first time achieved using engineered Corynebacterium glutamicum expressing PHB biosynthetic genes and displaying a-amylase on its cell surface. The engineered strain accumulated 6.4 wt% PHB from starch which was higher than that obtained from glucose (4.9 wt%). (C) 2012, The Society for Biotechnology, Japan. All rights reserved.
