A STUDY OF GROWTH CHARACTERISTICS IN SOYBEAN SPROUTS USING MICRO-BUBBLE TREATED WATER

Effects of micro-bubble treated water on the growth of soybean sprout were investigated. Air feeding rate was varied from 100 cc/min to 700 cc/min on this micro-bubble generator. Changes of pH in the culture water and some growth parameters of soybean sprout were observed. The pH of micro-bubble treated water with variance of air feeding rates was a little higher than that of tap water. The weights of the soybean sprouts using micro-bubble treated water with variance of air feeding rates were about 6% ~ 11% lower than that of tap water. The weights of root using micro-bubble treated water according to air feeding rate were about 42% ~ 53% lower than that of tap water also the lengths of root were measured about 60% ~ 70% lower than that of tap water.
