PROCESS FOR THE PRODUCTION OF CELLS WHICH ARE CAPABLE OF CONVERTING ARABINOSE

摘要

The invention relates to a process for the production of cells which are capable of converting arabinose, comprising the following steps: a)Introducing into a host strain that cannot convert arabinose, the genes AraA, araB and araD, this cell is designated as constructed cell; b)Subjecting the constructed cell to adaptive evolution until a cell that converts arabinose is obtained, c)Optionally, subjecting the first arabinose converting cell to adaptive evolution to improve the arabinose conversion; the cell produced in step b) or c) is designated as first arabinose converting cell; d)Analysing the full genome or part of the genome of the first arabinose converting cell and that of the constructed cell; e)Identifying single nucleotide polymorphisms (SNP's) in the first arabinose converting cell; and f)Using the information of the SNP's in rational design of a cell capable of converting arabinose; g)Construction of the cell capable of converting arabinose designed in step f).
