| We examined the effects of crude and eight pure material (${eta}$-sitosterol, ${eta}$-sitosterol-${eta}$-D-glucoside, 1-tetratriacontanol, hentriacontane, orizaterpenoid, stigmas-5-en-$3{alpha}$ 26-diacetate, stearic acid, myristic acid), extracted from rice hull, on growth inhibition of toxic cyanobacterium, Microcystis aeruginosa NIER 10010. Strains of M. aeruginosa and Daphnia magna, obtained from the NIER (Korea) and BBE (Germany), were cultured in the CB medium with hard water. For all four treatment concentrations 0, 10, 100 and $1,000{mu}g;L^{-1}$) of the crude extract, the cell number of M. aeruginosa was reduced by $59{sim}73%$ during the 7-day test period. Among eight kinds of pure extracts, ${eta}$-sitosterol-${eta}$-D-glucoside, hentriacontane and orizaterpenoid $(1,000{mu}g;L^{-1})$ exhibited relatively higher growth inhibition compared with other pure extracts. The mixture of three pure extracts (${eta}$-sitosterol-${eta}$-D-glucoside, hentriacontane and orizaterpenoid) showed the highest growth inhibition at $1,000{mu}g;L^{-1}$. Therefore, the synergistic effect was significantly highlighted by a mixture of the three pure extracts (p<0.05). Under the condition of $1,000{mu}g;L^{-1}$ in the crude extracts, D. magna exhibited survival rate by >85% for 96 hours. In conclusion, the growth inhibition of M. aeruginosa was probably attributed to the synergistic effect of various compounds extracted from the rice hull. |
