Article history: Received on: 04/08/2014 Revised on: 15/08/2014 Accepted on: 22/09/2014 Available online: 30/10/2014 The essential oils were prepared from Aster spathulifolius (ASE) and Vitex rotundifolia (VRE) by hydrodistillation and their chemical compositions were investigated by GC–MS. Analysis of ASE provided 15 components and eight of which were identified sesquiterpene compounds. The ma...

Promise of combined hydrothermal/chemical and mechanical refining for pretreatment of woody and herbaceous biomass.

Production of advanced biofuels from woody and herbaceous feedstocks is moving into commercialization. Biomass needs to be pretreated to overcome the physicochemical properties of biomass that hinder enzyme accessibility, impeding the conversion of the plant cell walls to fermentable sugars. Pretreatment also remains one of the most costly unit operations in the process and among the most criti...
