The purpose of this study at water quality pollutants to propose proper management method for the Osu-A unit watershed which is the influent tributary located upstream of the Sumjin -river among the 13 unit watersheds in the Sumjin-river water system. Analyzed the correlation between flow-pollution loading and the correlation between land use type, BOD and TP items, and analyzed 8-day intervals Cumulative Flow Duration Curve (CFDC) and Load Duration Curve (LDC) to evaluate water quality damage. As a result, both BOD and TP were larger than 1 and the concentration of water pollutants increased with increasing flow. BOD was positively correlated with Urban and Field, and TP was positively correlated with Field with 0.710. As a result of the LDC, BOD was analyzed that the target water quality was achieved with the excess rate of less than 50%, and TP exceeded the target water quality by 50.1%. BOD usually exceeded the standard value (exceedance probability 50%) at low flow zone and On the other hand, TP usually exceeded the standard value at high flow zone. Monthly BOD (April to June) and TP (May to August) exceeded the standard. Sewage Wastewater treatment and non-point pollution control is Osu-A unit watersheds are effective in improving BOD and TP.

We investigated the effect of inhibitory compounds derived lignocellulosic hydrolysates on cell growth, sugar consumption and ethanol productivity, and also we intended to identify the potential for ethanol production based on lignocellulosic hydrolysates. Cell growth and ethanol production in the presence of acetate were initiated after 12 hr. Furans showed a longer lag time and phenolics showed a significant effect on strain and ethanol production in comparison to other model compounds. In the case of lignocellulosic hydrolysates, the acetate strongly affected cell growth and ethanol production.
