Abstract: Proposed is a method for CO2-free waste gas fermentation using microbial strains, and the method is capable of maximizing a consumption rate of gaseous substrates by additionally injecting methanol during a fermentation process of the microbial strains, and converting CO2, a greenhouse gas, generated during the fermentation process into hydrocarbon products therethrough. The method may comprise: 1) injecting microbial strains into a bioreactor; and 2) injecting gaseous substrates and methanol into the bioreactor, and converting the gaseous substrates and the methanol into hydrocarbon products through fermentation of the microbial strains, wherein all CO2 present inside the bioreactor is consumed and converted into hydrocarbon products.
