Disclosed is a liquid biofuel comprising carbonaceous material particles having a D50 ranging from 0.1 μm to 200 μm suspended in a liquid biodiesel composition.

Chemically defined culture medium and culture conditions that allow bacteria to assimilate dinitrogen gas (N.sub.2) as a nitrogen source during bio-ethanol production are disclosed herein. Methods of bioethanol production using the chemically defined culture medium and culture conditions are also disclosed.

A culture product comprising a large quantity of ethyl benzoate and has a more complex and fresher fruity aroma than a chemically synthesized product.

The culture product is obtained by culturing a microorganism belonging to the genus Wickerhamomyces in a milk component-containing culture medium.

The present invention discloses a device and method for generating high-purity hydrogen by biomass pyrolysis-chemical looping combustion. The device comprises a biomass pyrolysis unit, a chemical looping hydrogen generation unit and a waste heat recovery unit; the biomass pyrolysis unit comprises a vertical bin, a screw feeder, a rotary kiln pyrolysis reactor and a high temperature filter; the chemical looping hydrogen generation unit comprises a path switching system of intake gas end, at least one packed bed reactor and a path switching system of tail gas end, wherein the packed bed reactor is composed of three parallel packed bed reactors I, II and III, which are continuously subjected to fuel reduction-steam oxidation-air combustion stages (steam purging stage) successively; the waste heat recovery unit comprises a waste heat boiler, a cooler and a gas-liquid separator. According to the present invention, a process flow of generating hydrogen from biomass is short, high-purity hydrogen can be obtained by simple condensation and water removal of a hydrogen-containing product that is generated after entrance of a pyrolysis gas into the chemical looping hydrogen generation unit, no complex gas purification device is employed, and the costs for hydrogen generation are low.

The invention also relates to nucleic acid constructs, vectors, and host cells comprising the polynucleotides as well as methods of producing and using the polypeptides.

Microorganisms and methods of producing n-butyraldehyde with enhanced yields are presented in which a microorganism is engineered to enhance the conversion of a carbon source into n-butyraldehyde. The n-butyraldehyde is recovered by way of a gas stripping process that occurs during the conversion process, providing significantly greater product yield than post-fermentation recovery of n-butyraldehyde alone.
