Provided is an apparatus for processing an object to be processed. SOLUTION: A gas-liquid mixing means which has a nozzle portion and mixes an object to be processed containing microorganisms and a gas, and an object which supplies pressure to the object to be processed and supplies the object to the gas-liquid mixing means. A processing body supply means, and a gas pressure supply means for applying pressure to the gas to supply the gas to the gas-liquid mixing means, wherein the gas mixed into the processing object by the gas pressure supply means is formed into fine bubbles to be processed. The nozzle is configured to be ejected together with the body. |
