Evaluation of hydrothermal pretreatment and fermentation to improve lipid and ethanol production from corn germ meal
… The objectives of this work were to use hydrothermal pretreatment on oil bearing biomass for lipid enrichment and to investigate how lipid profiles changed during simultaneous saccharification and cofermentation (SSCF). Corn germ meal was chosen as a model for lipid producing energy crops …

Improving the anaerobic co-digestion of pelagic Sargassum and food waste into biogas and a bio-fertiliser using hydrothermal pre-treatment: Concept to application in the Caribbean
… content result in a low biomethane potential. Hydrothermal pre-treatment and co-digestion are viable processes which can be applied to these brown seaweeds for biogas enhancement. Hydrothermal pretreatment is green technology which utilizes pressurised liquid “hot water” to enhance biomass …

Application of physicochemical and biological pretreatments to enhance volatile fatty acids production via Dark Fermentation from agri-food waste
… it necessitates the application of costly pretreatments to ensure adequate solubilization of the organic matter present in the biomass. Residual biomass is a cheap carbon source with high volume availability and decentralized geographical distribution, but its use requires the optimization …

Miscanthus conversion to ethanol: Effect of particle size and pretreatment conditions for hot water
… hydrolysis, which necessitates an expensive pretreatment in combination with a heavy enzyme dosage. The objective of this study was to develop an e fficient process for conversion of Miscanthus x giganteus to ethanol using hammer milling for reduction of particle size followed by a …

Exploring hydrothermal reactions : from prebiotic synthesis to green chemistry
In this thesis chemical reactions under hydrothermal conditions were explored, whereby emphasis was put on green chemistry. Water at high temperature and pressure acts as a benign solvent. Motivation to work under hydrothermal conditions was well-founded in the tunability of physicochemical …

Adsorption and membrane filtration for the separation and valorization of hemicellulose from organosolv beechwood hydrolyzates
… other hand, for the separation of xylose from hydrothermally pretreated beechwood hydrolyzate by nanofiltration. The ultrafiltration was optimized in terms of high permeate flux and hemicellulose retention as well as low lignin retention as a function of transmembrane pressure, temperature, and …
