Abstract:
PROBLEM TO BE SOLVED: To efficiently produce a polyester having good color tone, when producing the polyester using a dicarboxylic acid component and a diol derived from a biomass resource as raw materials.SOLUTION: As a raw material diol derived from a biomass resource, used is one containing a cyclic carbonyl compound having 5 or 6 carbon atoms in an amount of 0.01 to 12 mass ppm. When producing a polyester using the diol derived from biomass resource, color tone of the polyester obtained has a strong correlation with a content of a carbonyl compound, especially the cyclic carbonyl compound having 5 or 6 carbon atoms. By controlling the content of the cyclic carbonyl compound having 5 or 6 carbon atoms in the raw material diol, color tone of the polyester becomes good.

PROBLEM TO BE SOLVED: To provide multicellular metabolic models and methods thereof.SOLUTION: The present invention provides in silico models that describe the interconnections between genes in the Homo sapiens genome and their associated reactions and reactants. The invention also provides in silico models that describe interconnections between different biochemical networks within a cell as well as between cells. The interconnections among different biochemical networks between cells can describe interactions between, for example, groups of cells including cells within different locations, tissues, organs or between cells carrying out different functions of a multicellular organism. Therefore, the models can be used to stimulate different aspects of the cellular behavior of a cell derived from a multicellular organism, including a human cell, as well as be used to stimulate different aspects of cellular behavioral interactions of groups of cells.

PROBLEM TO BE SOLVED: To provide a constraints-based model for increasing the number and variety of organisms for which genomes are being sequenced. SOLUTION: A process includes computer implemented steps of: (a) accessing a database of network gene components including an annotated network set of open reading frames (ORFs) of a bioparticle genome; (b) forming a data structure associating the network gene components with network reaction components, wherein the data structure establishes a data set specifying a network model of connectivity and flow of the network reaction components; and (c) transforming the data set into a mathematical description of reactant fluxes defining the network model of connectivity and flow, wherein the mathematical description defines a scalable output network model of a bioparticle.
