Chementator: PHAs from switchgrass  

Metabolix, Inc. (Cambridge, Mass.; www.metabolix.com) has demonstrated, in recently completed greenhouse trials, that switchgrass plants engineered using the firm’s multi-gene expression technology produced significant amounts polyhydroxybutyrate (a polyhydroxyalkanoate; PHA) bioplastics in leaf tissues. The result is said to be the…
