This study was performed to investigate the changing encironment of Keum River after the construction of the floodgate at the mouth of Keum River. Samples were taken from the surface wateres at 3 stations near the floodgate of the artificial lake Keumgang to measure the physico-chemikcal and microbiological water qualities from May, 2001 to April, 2002. The results were as follows; water temperature ranged from 2 to 28℃, and pH values caried from 7.5 to 9.1 respectively. The dissolced oxygen contents and COD of each station varied from 7.13 to 14.10 mg l⁻¹ and from 5.2 to 9.4 mg l⁻¹resoectively. And total nitrogen and total phosphate values varied from 0.99 to 3.15 mg l⁻¹, and from 0.01 to 0.12 mg l⁻¹ during survey periods,which meant the sampling stations have set in eutrophic level The population density of heterotrophic bacteria ranged from 0.4±0.1 x 103 cfu ml⁻¹ to 3.5±0.6 x 10³cfu ml⁻¹ for during survey periods. The population densities of physiological groups of aerobic bacteria ranged from 2.0±1.0 x 10² to 1.7±0.2 x 10³ cfu ml⁻¹ for amylolytic bacteria, from 0.3±0.1 x 10² to 1.3±+0.5 x 10³ cfu ml⁻¹ for proteolytix bacteria, from 0.2±0.1 x 10³ to 4.9±1.3 x 10³ cfu ml⁻¹ for lipolytic bacteria, and from 0.2±0.1 x 10² to 2.7±0.7 x 10³ cfu ml⁻¹ for cellulolytic bacteria during survey periods, respectively. Among the measured numbers of physiological groups of bacteria, lipolytic bacteria showed the highest population density. Howecer, the numbers of amylolytic, pyoteolytic, and cellulolylic bacteria showed the similar tendency. |
