Enzyme production and use is the dominant contributor to all environmental impact categories for all of the process configurations that were tested (Fig. 4). This is due to the fossil energy needed during the production of the enzyme [37]. The explicit inclusion of the electrical power input ...
1.A method for the production of ethanol comprising feeding a fermentable lignocellulosic biomass feed into a continuous fermentation, said fermentable lignocellulosic biomass feed having being obtained by treatment of a starting lignocellulosic biomass to liberate carbohydrates contained therein and containing...
Thus, the present invention provides a process comprising enzyme production using solid substrate culture, the composition of an enzyme preparation containing multiple cellulase and hemicellulase activities and a second step to produce ethanol. I. Strain Selection In one aspect of the present invention,...
Schematic diagram of ethanol production process from biosyngas (thermochemical conversion). P. Roy, A. Dutta12energy or even produces it [58,59] because of the implementation of multieffect columns followed by heat integration (hot and cold streams) in the process. MINLP approach is also used ...
Figure 2. PRISMA flow diagram for the systematic review of PubMed, Web of Science, and the Scopus databases; “auto-brewery syndrome”, “endogenous ethanol production”, or “gut fermentation syndrome” were the potential search terms contained in the titles. 2.1. Blood Ethanol Levels Blood ...
Bacteriophage infection and strain generation are serious problems in the ABE fermentation process. Bacteriophage infection is manifested as an unexpectedly early slowing of growth and gas production (H2 and CO2). Because bacteriophages have a narrow host range, it was a common strategy to keep spores...
Production of cheese whey in the EU exceeded 55 million tons in 2022, resulting in lactose-rich effluents that pose significant environmental challenges. To address this issue, the present study investigated cheese-whey treatment via membrane filtration
Ethanol production inputs include the following: biomass, petroleum fuels, electrical energy, chemicals, and enzymes. Fig. 2 Process flow and system boundary diagram for feedstock production and cellulosic ethanol production. Solid lines are material flows, dashed lines are internal biorefinery heat and...
The ethanol precipitation process (EPP) has many advantages, such as simple operation, easy amplification, and solvent safety. The EPP can effectively remove highly polar molecules such as sugars, salts, and proteins, and it is beneficial to reduce the dosage [1]. In the production of TCM ...
A process of producing ethanol from whole stillage, includes obtaining a supply of whole stillage from an ethanol production facility after ethanol has been extracted therefrom; pre-treating the whole
