Abstract: A sterilizing method for sterilizing a sterilization object housed in a chamber 11 includes an ozone preparation step S504 for filling an inside of a buffer tank 34 with ozone gas, and an ozone injection step S505 for injecting the ozone gas filled in the inside of the buffer tank 34 into the chamber 11.

Abstract: A sterilizing method for sterilizing a sterilization object housed in a chamber (11) includes a first vapor injection step (S104) of injecting vapor produced from a first aqueous solution of hydrogen peroxide to the inside of the chamber (11), an ozone injection step (S107) of injecting ozone gas to the inside of the chamber (11) after the first vapor injection step (S104), and a second vapor injection step (S109) of injecting vapor produced from pure water or vapor produced from a second aqueous solution of hydrogen peroxide to the inside of the chamber (11) after the ozone injection step (S107).

Abstract: A sterilizing method includes a preliminary decompression step (S200) of decompressing the inside of a chamber (11) with respect to an atmospheric pressure after a sterilization object wrapped with a wrapping member made from a material that absorbs ozone gas and hydrogen peroxide is housed in the chamber (11), an ozone adsorption step (S300) of injecting ozone gas to the inside of the chamber (11) under a decompressed state achieved in the preliminary decompression step (S200) to cause the ozone gas to be adsorbed to the wrapping member, and a sterilization step (S500) of sterilizing the sterilization object using the zone gas and hydrogen peroxide after the ozone adsorption step (S300).

Abstract: The culture device (100, 200) for culturing algae includes a culture pond (110) including an opening (112) on an upper side thereof and accommodating an alga solution (M) as a culture solution containing algae; a sheet (130) having optical transparency and flexibility, the sheet sealing at least a portion of the opening (112) of the culture pond (110); and a gas supply unit (124, 160, 212) used to supply high concentration CO2 gas having a higher concentration of carbon dioxide than that of the atmosphere, between the culture pond (110) and the sheet (130). A gas storage space (G) to store gas between a liquid surface (114) of the alga solution (M) and the sheet (130) is formed by at least part of the supplied high concentration CO2 gas.
