摘要:
The present invention is related to a method for improving a strain on the basis of in silico analysis, in which it compares the genomic information of a target strain for producing a useful substance to the genomic information of a strain overproducing the useful substance so as to primarily screen genes unnecessary for the overproduction of the useful substance, and then to secondarily screen genes to be deleted through performing simulation with metabolic flux analysis. According to the present invention, an improved strain can be effectively constructed by the metabolic and genetic engineering approach comprising comparatively analyzing the genomic information of a target strain for producing a useful substance and the genomic information of a strain producing a large amount of the useful substance to screen candidate genes and performing in silico simulation on the screened candidate genes to select a combination of genes to be deleted, which shows an improvement in the production of the useful substance. Accordingly, the time, effort and cost required for an actual wet test can be significantly reduced.

The present invention relates to an MFA (Metabolic Flux Analysis) information system using an XML (eXtensible Markup Language) and an operating method thereof. More specifically, the invention relates to an MFA information system and an operating method thereof, which generates, edits, stores and visualizes an MFA model feature and an MFA object using XML, and edits, stores and visualizes the result obtained by performing MFA based on the object. The present invention provides the MFA information system and method capable of generating, editing, storing and visualizing MFA model features and MFA objects using XML. Accordingly, MFA can be easily performed by utilizing advantages of XML, such as transplantation, reusability, deciphering, scalability, flexibility and effective data exchange, and thus the present invention can be applied to cell improvement using metabolic engineering.

The present invention relates to an in silico method for improving an organism on the basis of the flux sum (φ) of metabolites, and more particularly to a method for screening key metabolites that increase the production yield of a useful substance, the method comprising defining the metabolite utilization of an organism for producing a useful substance as flux sum and perturbing the flux sum, as well as a method for improving an organism producing a useful substance, the method comprising deleting and/or amplifying genes associated with the aforementioned screened key metabolites. According to the present invention, the correlation between specific metabolites and useful substance production can be exactly predicted, so that it is possible to develop an organism having increased useful substance production by introducing and/or amplifying and/or deleting genes expressing enzymes associated with the specific metabolites. In addition, it is also possible to increase the production of a useful substance by adding specific metabolites during culture.
