Escherichia coli mutant strain with enhanced growth rate and preparation method thereof

摘要

The present invention relates to an Escherichia coli mutant having an increased growth rate and a method for producing the Escherichia coli mutant, and a method for increasing the growth rate of bacteria through the multiple replication system and the Escherichia coli mutant strain, Through the high efficiency production of the objective product, it is possible to realize the reduction of the direct cost of the raw material accompanied by the growth of the medium or other microorganisms, and the economical effect such as the reduction of the incubation time and the reduction of the facility cost, electricity cost and labor cost can be expected. In addition, it can be expected that the added value will be induced through indirect effects such as improving the price and export competitiveness through productivity improvement.
