Oxygen and Air Nanobubble Water Solution Promote the Growth of Plants, Fishes, and Mice
Brassica campestris (32 stumps in each group) were hydroponically cultured for 4 weeks. Water was circulated (38 L/min) in a tank (125 L/tank) and air-nanobubble solution was continuously generated using the nanobubble aerator. The water level of the tank and water temperature (from 23.2 to 24.3°C) was maintained throughout the culture. Data are shown as mean ± S.E. (n = 32 in each group). **P<0.01; ***P<0.001.
