Apparatuses, computer media, and methods for determining a value of a forest factory. A stump land value component and a biomass component of a forest factory are determined. A value of the forest factory is obtained by combining the components. The stump land value component may be normalized by a crop rotation time period. A carbon value component of a forest factory may be determined and the value of the forest factory adjusted. A land parcel may be partitioned into land partitions, in which forest parameters are associated with each land partition. A stump land value component, a biomass fuel value component, and a carbon credit value component may be determined from the land partitions. The carbon credit value component may be determined a percentage of coniferous trees, deciduous trees, and corresponding constant values of oxygen generation.

Provided are methods for aqueous isolation of depolymerized lignin in high yield from a lignin-containing biomass composition, comprising positioning a lignin-containing biomass composition into a flowthrough thermal reactor chamber to provide for passage of an aqueous fluid therethrough, contacting the lignin biomass composition with the aqueous fluid under elevated temperature conditions sufficient to provide for lignin release and depolymerization, flowing the aqueous fluid through the reactor chamber under the elevated temperature conditions, to provide an output aqueous fluid comprising released depolymerized lignin, and collecting the depolymerized lignin. Particular aspects further comprise hydrogenation and/or hydrodeoxygenation (HDO) of the released depolymerized lignin with a catalyst or catalyst system for deconstruction of the released depolymerized lignin into lower molecular weight reactive lignin moieties and oligomers amenable for subsequent removal of oxygen to produce hydrocarbon fuels and/or chemicals and/or compounds. Systems for practicing the methods are also provided, along with highly purified depolymerized lignin.

A method of preserving a biomass. The method comprises adding an acid solution to a biomass comprising microalgae to form an acidified microalgae biomass composition. The acidified microalgae biomass composition is stored under anaerobic conditions without inoculating the acidified microalgae biomass composition with bacteria. An additional method of preserving a biomass comprises storing the acidified microalgae biomass composition under anaerobic conditions and exposing the acidified microalgae biomass composition to carbon dioxide, nitrogen, or a combination thereof to produce a coproduct comprising succinic acid. Yet another method of preserving a biomass comprises storing the acidified microalgae biomass composition under anaerobic conditions and in the presence of carbon dioxide. A preserved biomass is also disclosed.

The invention relates to a microbial biomass composition produced from a heterotrophic fermentation whose fatty acid profile exhibits: an eicosapentaenoic acid (EPA) to arachidonic acid (ARA) ratio of about 11:1 or more; an EPA to total co-concentrating fatty acid ratio of about 8:1 or more, extract compositions, and methods of producing such compositions.

The invention relates to a method for determining the organoleptic quality of a protein-rich microalgal biomass composition, comprising the determination of the content of 11 volatile organic compounds, wherein the 11 volatile organic compounds are pentanal, hexanal, 1-octen-3-ol, 2-pentylfuran, octanal, 3,5-octadien-2-ol (or 3-octen-2-one), 3,5-octadien-2-one, nonanal, 2-no-nenal, (E,E)-2,4-nonadienal and hexanoic acid.

The present disclosure relates to a physically pretreated biomass composition, which enables chemical treatment in a biomass composition comprising a high concentration of a biomass substrate, and a preparation method thereof.

Through specific physical pretreatment (attrition milling) of herbaceous biomass, the physically pretreated biomass composition has fluidity/flowability at a substrate concentration of biomass of 20% (w/w) (biomass:solvent=1:4) or above, and thus the pretreatment cost may be reduced, and it is very useful in biomass treatment processes.

The present disclosure relates to a physically pretreated biomass composition capable of membrane filtration treatment in a biomass solid-liquid separation process, and a method for preparing sugar therefrom.

The physically pretreated biomass composition is very useful for the biomass treatment process because MF clogging phenomena do not occur through specific physical pretreatment (attrition milling) of herbaceous biomass and because MF passage speed is improved such that MF can be used in the biomass solid-liquid separation process.

This invention is to a biomass composition of 5 and 6 carbon sugars, lignin, and cellulose which has been steam exploded and the composition has a very high enzyme accessibility at 24 hours for hydrolysis.

The invention relates to a method and to a device for generating a biomass preparation (biomass composition), particularly preparation of fermentable biomass. Through combining biological, mechanical and/or microorganism activators for thermal activation, biomass reactants difficult to digest, especially lignin in biomass, can be digested and allowed to be fermented.
