The present invention provides, inter alia, a method for combined preparation of saccharides, alcohols (biofuel) and biodiesel using a composition comprising interior hydrophobic or hydrophilic medium encapsulated by a layer comprising cellulose, cellulose derivative material, and/or starch surrounded by a hydrophilic or hydrophobic medium, respectively.
摘要:
Methods for production of a bioproduct with a microorganism and selective extraction of bioproducts from a fermentation broth. The methods may include mixing a carbon source, a nitrogen source, and an extractant-depleted raffinate to form a fermentation medium, and fermenting the medium with a microorganism to form a fermentation broth having at least one bioproduct. The bioproduct may be extracted from the fermentation broth with an extractant comprising an oxygenated organic compound and a hydrocarbon to form an extract and a raffinate, and the extract may be further separated from the raffinate. The bioproduct may then be separated from the extract, and the extractant may be separated from the raffinate to regenerate the extract-depleted raffinate.
摘要:
A presente invenção descreve um cassete de expressão para transformar célula eucariótica que compreende a sequência de nucleotídeos (SEQ ID NO: 2) codificadora de peptídeo com característica xilose isomerase (SEQ ID NO:1), opcionalmente compreendendo também outros genes da via das pentoses fosfato. A invenção descreve também micro-organismo geneticamente modificado pela inserção do cassete de expressão descrito, capaz de consumir xilose e converter etanol quando comparado ao seu correspondente sem as ditas modificações. Descreve-se também processo para produção de biocombustíveis e bioquímicos, preferencialmente etanol, a partir de açúcares abundantes na porção lignocelulósica da biomassa vegetal, principalmente pentoses e, entre as pentoses, principalmente xilose. São descritos também biocombustíveis, preferencialmente etanol, e bioquímicos produzidos pelo processo da invenção.

摘要:
Provided are microorganisms, e.g., the Saccharomyces yeast, that have been made able to co-ferment xylose sugar obtained from hydrolyzing plant cellulosic biomass from trees, grasses, straws, etc., with glucose that can be obtained from hydrolyzing either edible feedstocks such as starch, cane sugar, etc., or from hydrolyzing cellulose from various types of non-edible cellulosic biomass. The microorganisms are also capable of expressing an amylase, e.g., glucoamylase, having nonnegligible enzymatic activity, capable of producing glucose from oligo- or polysaccharides obtained by treating soluble starch with a-amylase. In some embodiments, nucleotidic material is provided comprising genes actively expressing xylose reductase, xylitol dehydrogenase and xylulokinase, as well as an active gene expressing glucoamylase. Vectors and other compositions of matter are provided as well.
摘要:
Methods and compositions relating to processing of plant material into bacterial feedstock, such as bacterial feedstock suitable for nanocellulose production, are disclosed. Cellulosic plant fiber may be contacted with a catalyst such as an acid catalyst or an enzymatic catalyst or both, and the mixture can be hydrolyzed into a hydrolysate. The hydrolysate may be used to form a culture medium which can be used to support bacterial growth to form the nanocellulose.
摘要:
An method for growing a microbial organism, comprising the cultivation of the microbial organism in the presence of a hydrolyzed composition obtained from a thermally treated ligno-cellulosic biomass. The treatment preferably comprises a fiber shives reduction step. The hydrolyzed composition has very few inhibitor compounds and the microbial organism feed with the hydrolyzed composition grows in a short time with a high duplication factor.
摘要:
The invention relates to a solid inoculum carried in a superabsorbent agro-pellet with a variable volume, operating in a natural mini fermenter preloaded with an anhydrous nutritive medium, encouraging rapid regrowth of the viable micro-organisms and the continuous multiplication thereof. The liquid inoculum incorporated into the carrier at a low density of microbial cells is preferably comprised between 1/500e and 1/10e of the density recommended by the norm for a liquid inoculum of the same strain. The bioaugmentation of the microbial population is between 104 and 106 additional microbial cells. The solid inoculum according to the invention allows the preservation of the microorganisms and the handling thereof in advantageous conditions.It is not exposed to soil leaching caused by water. Said inoculum is used for the biological treatment of crops for the development and/or the preservation thereof from parasite attacks.
