A method of making an ethanol composition and a separate galactose composition by fermentation is described. The method does not require wheat substrates and does not require a distillation step to separate out the ethanol. The methods comprises treating the lactose containing substrate with a beta-galactosidase enzyme to provide an enzyme treated substrate in which at least some of the lactose in the substrate has been enzymatically converted into glucose and galactose, fermenting in a fermentation medium comprising the enzyme-treated substrate a glucose fermenting yeast to provide a fermentation broth containing ethanol and galactose, and separating the fermentation broth into an ethanol composition and a separate galactose composition.

Resumen de: WO2025193297A1
Under current practices, agricultural or landscaping waste left in a field or forestry waste left in a forest will decay and release greenhouse gases. In addition, forestry waste also poses a high risk for fires. Accordingly, mechanisms are provided to allow efficient conversion under anaerobic conditions of biomass, such as agricultural or forestry waste, into biocarbon product, such as biochar, biocoal, inert carbon and/or activated carbon, using molten salts as a more efficient heat transfer medium than conventional heat. Specifically, biomass is converted into biocarbon product during a supertorrefaction process during which molten salts are pumped under anaerobic conditions from a molten salt reservoir to a batch process cooker that holds the biomass. The salts are washed from the resulting biocarbon product as needed.
Resumen de: WO2025192252A1
According to the present invention, ethanol can be efficiently obtained by microbial fermentation using a carbon source such as CO or CO2 as a substrate. A recombinant bacterium according to the present invention is derived from a thermophilic acetic acid-producing bacterium having a metabolic pathway for producing acetic acid through acetyl-CoA as an intermediate product from a carbon source. The recombinant bacterium has a deficiency in at least a portion of enzymes involved in the metabolic pathway through genetic engineering, and produces ethanol by expressing a foreign NADPH-dependent heat-resistant enzyme that catalyzes a reaction for producing acetaldehyde from acetyl-CoA and a heat-resistant enzyme that catalyzes a reaction for producing ethanol from acetaldehyde.
