Productivity, measured in terms of tonnage of grapes picked in a given amount of time, can be increased by use of equipment that will transport the picker, improve picking visibility, and move the fruit into containers. These tests with a mobile plat

Abstract Background Lignocellulosic biomass is considered as a potential source for sustainable biofuels. In the conversion process, a pretreatment step is necessary in order to overcome the biomass recalcitrance and allow for sufficient fermentable

Biomass pretreatment is a mandatory step for the biochemical conversion of lignocellulose to chemicals. During pretreatment, soluble compounds are released into the prehydrolyzate that inhibit the enzymatic hydrolysis step. In this work, we investiga
