The purpose of this study is to investigate anti-tumor activities, general composition, elemental composition and mineral contents of fermented liquid stem, root and fruit of Opuntia humifusa. In the general composition, the energy, crude protein, crude lipid and crude carbohydrate contents of fermented liquid stem were 86.21 Kcal, 0.92$\%$, 0.12$\%$, and 20.34$\%$, respectively. Fermented liquid fruit showed 65.32 Kcal, 1.04$\%$, 0.08$\%$, and 15.15$\%$. In mineral analysis, fermented liquid stem and fruit showed 1,800 and 388 mg of calcium per 100g. The ferrous concentrations of fermented liquid stem and fruit were 21 and 10 mg per 100 g, respectively. Methanol, ethanol and water extracts of nonfermented liquid stem and fruit did not inhibit the proliferation in human cervical cancer cells (Caski, SiHa and HaCaT), but the fermented liquid fruit showed the inhibition of Proliferation with dose-response manner in Caski and SiHa cells, but not HaCaT. Therefore, it suggests that fermented cactus may be used as one of potential adjuvant for the treatment of cervical carcinomas.

Two feeding experiments were conducted to investigate the effects of fermented cactus fruit (Opuntia ficusindica) fluid (FCFF) as a feed additive to a commercial diet on the growth of red sea bream, Pagrus major, and to determine an effective dose. FCFF was prepared by mixing crushed cactus fruit with a starch solution and commercially available microorganisms for 2 weeks at room temperature. Three triplicate groups of red sea bream had initial mean weights of 84.1 g (Exp-1) and 5.1 g (Exp-2) and were fed experimental diets containing 0%, 1%, and 5% FCFF for 2 months (Exp-1) and 0%, 0.2%, 0.5%, and 1% FCFF for 3 months (Exp-2), respectively. In experiment 1, the mean body weight of fish fed the diet containing 1% FCFF was significantly higher (P<0.05) than that of fish fed the diet without FCFF. The survival rate was highest in fish fed the diet containing 1% FCFF, although the difference was not statistically significant. The feed gain ratio (FGR), specific growth rate (SGR), and condition factor (CF) values of fish fed the diet containing 1% FCFF were higher than those of fish in the other dietary groups that received lower levels of FCFF. The daily feeding rate (DFR) of fish fed the diet containing 1% FCFF was slightly lower but not statistically different than the DFR values of fish in the other dietary groups. In experiment 2, the final mean body weight of fish fed the diet containing 1% FCFF was significantly (P<0.05) higher than the mean weight of fish in the control group. The FGR, SGR, and CF values of fish fed the diet containing 1% FCFF were better than the values from fish in the other dietary groups that received lower levels of FCFF, although the differences were not statistically significant. However, the DFR of fish fed the diet containing 1% FCFF was lower than those of fish in the other groups. These results suggest that FCFF could be used as a feed additive in commercial fish food and a preferable level of supplementation is at least 1.0% in fingerling and young red sea bream.
