TRANSFORMANTS WITH ENHANCED PRODUCTIVITY OF BIOMASS AND A METHOD OF PRODUCTION BIOMASS USING THEREOF

摘要

The present invention relates to a transformant with improved biomass production capability through a defect in a specific signaling system and a biomass production method using the same. In the transformant provided by the present invention, the gene of RegA, which is a signaling protein, is deleted in the genome, so that the proliferation efficiency in methane is remarkably improved. Therefore, when biomass is produced using the transformant, it is possible to produce more biomass from the same amount of methane compared to wild-type microorganisms, thereby reducing the use of methane as a carbon source and an energy source. That is, the transformant can contribute to reducing the cost of biomass production, and thus has a lot of industrial applicability.
