A method for remedying an environment containing a pollutant using microorganisms comprising a step of injecting a liquid containing a microorganism which can decompose the pollutant into a predetermined site of the environment to be remedied, wherein a gas has been dissolved into or mixed with the liquid by applying a pressure higher than the pressure at the injection site and the liquid evolves the gas when injected into the predetermined site, and an apparatus which comprises a means for injecting a liquid containing a microorganism which can decompose a pollutant into a predetermined site of the environment, wherein the means injects the liquid in which a gas has been dissolved into or mixed with by applying a pressure higher than the pressure at the injection site, into the environment under a pressure so that the gas does not evolve from the liquid before injection.
