Ethanol production implies in by-products generation, mainly vinasse and stillage, respectively generated from sugarcane corn ethanol flex plants. Both require efficient treatment routes to avoid environmental side-effects support energy recovery. Accordingly, the aim of this study was evaluate techno-economic potential bioenergy (electric thermal energy) anaerobic digestion (AD) stillage. Thre...

The aims of this work were to isolate microorganisms from vinasse (V) and black liquor (BL), by-products alcohol paper industries assess their potential as substrates produce biosurfactants. Thirty-nine microorganisms, 19 V (acidophilic, a1 a19) 20 BL (alkaliphilic, b1 b20) isolated. A high- throughput method was design set up for surface tension ( γ ) measurement. In the first screening, 15/39...

BACKGROUND The availability of feedstock options is a key to meeting the volumetric requirement of 136.3 billion liters of renewable fuels per year beginning in 2022, as required in the US 2007 Energy Independence and Security Act. Life-cycle greenhouse gas (GHG) emissions of sorghum-based ethanol need to be assessed for sorghum to play a role in meeting that requirement. RESULTS Multiple sor...
