Vargas Sepulveda, Hector Mauricio

There has been an increasing interest in the use of biorefining feedstocks for the production of value-added products. Seaweeds are of special interest, due to the fact that they do not compete for land use with food crops, have low to no lignin content, and can be grown in waste water or at sea,...

Currently, non-food carbon sources are making a valuable contribution to development of the next generation of hydrocarbon-based renewable fuels and value-added products. As non-food carbon feedstocks with low or negative value, yellow and brown greases, as well as biosolids, can potentially be...

Switchable solvents are a novel class of chemicals that are characterized with the ability to reversibly switch specific properties with the addition/removal of a trigger. For instance, a solution of low ionic strength can become one of high ionic strength, and vice versa. Switchable solvents...

Contamination by lactic acid bacteria is a major source of inefficiency in the bioethanol industry. Contaminated fermentations exhibit lowered ethanol yields and contamination events often require shutdown of the entire process for cleaning and decontamination. The first objective of this study...

Jin, Yiqiong

The vast majority of global bio-ethanol production uses food crops as the primary feedstocks, which leads to the high dependence of ethanol production cost on the price of the crop-based carbon resources. The demand, and interests, to use cheaper non-crop-based carbon sources for the ethanol...

Immobilization has the potential to make enzyme utilization more cost efficient, but reduced enzymatic activity makes it unfeasible. The purpose of this study was to develop immobilized cellulase systems on silica supports that retain high enzymatic activity. Two of the four systems created...
