민상현,이옥재,안태영 ( Sang Hyun Min,Ok Jae Rhee,Tae Young Ahn ) 한국하천호수학회 1995 생태와 환경 Vol.28 No.4
Nitrification and denitrification potential were detected in the sediment of Lake Soyang by ^14C-bicarbonate incorporation and acetylene blockage method, respectively. The range of nitrification potential was 0.01∼2.49㎍-N gdwt^-1day^-1 and that of denitrification potential was 0.08∼5.25㎍-N gdwt^-1day^-1. Nitrification potential was showed the highest value at station 4 where organic carbon was rich. It was a high value at station 1 and 2 and was a low value with deep. Denitrification potential was showed the lowest value at station 1 in which organic carbon content was poor and water depth was shallow and was showed the highest value at station 4. Nitrification was correlated positively with NH_4^+-N and denitrification was correlated positively with organic carbon. The inorganic nitrogen reduction was comparatively superior to the inorganic nitrogen oxidation at all stations. So it was assumed to loss of nitrogen source from sediment.

The nitrification rate and environmental factors were estimated 12 times at 4 stations from March 1992 to January 1994 in Daechung reservoir. The number of nitrifying bacteria and nitrification rate were measured with MPN and ^14C-dark incorporation method, respectively. The distribution of ammonia-oxidizing bacteria was 0.5∼220MPNml^-1(mean, 13MPNml^-1) and that of nitrite-oxidizing bacteria was ND-42MPNml^-1(mean,3MPNml^-1). The range of nitrification rate was 0.01∼7.15㎍-Nl^-1day^-1(mean, 0.74㎍-Nl^-1day^-1) and the highest value was 7.15㎍-Nl^-1day^-1 at station 3 where lots of fishfarm were located. Being showed through multiple regression analysis from all data estimated, the distribution of nitrification was affected by change of ammonia concentration, but not affected by nitrifying bacterial population.

The nitrification rate and environmental factors were estimated 10 times from August 1992 to October 1993 in Lake Soyang. The number of nitrifying bacteria and nitrification rate were measured with MPN and ^14C-dark incorporation method, respectively. The distribution of ammonia-oxidizing bacteria was 0.5-220MPNml^-1 (mean, 11MPNml^-1) and that of nitrite-oxidizing bacteria was 0.5-92MPNml^-1(mean, 9MPNml^-1). The range of nitrification was estimated 0.01-2.25㎍-Nl^-1day^-1(mean,0.28㎍-Nl^-1day^-1). It was shown through multiple regression analysis from all data that the major factor affecting to nitrification rate was water temperature and the minor factor was pH. The distribution of nitrification rate and ammonia-oxidizing bacteria were not correlated.

Ammonia oxidizing bacteria associated with the nitrification activity were 144 to 1,860 MPN/100㎖ (mean : 755 MPN/100㎖) in April, 300 to 9,200 MPN/100㎖ (mean : 2,062 MPN/100㎖) in June and 220 to 1,060 MPN/100㎖(mean : 520 MPN/100㎖) in August. Nitrite oxidizing bacteria which were also relative to the nitrification activity were 122 to 780 MPN/100㎖ (mean : 361 MPN/100㎖) in April, 200 to 22,000 MPN/100㎖ (mean : 3,792 MPN/100㎖) in August. The value of ammonia and nitrite oxidizing bacteria was significantly high in June. The range of nitrification activity showed that 0.01∼0.85 ㎍-N/ℓ/day (mean : 0.13 ㎍-N/ℓ/day) in April, 0.18∼1.8 ㎍-N/ℓ/day (mean : 0.78 ㎍-N/ℓ/day) in June and 0.05∼1.14 ㎍-N/ℓ/day (mean : 0.56 ㎍-N/ℓ/day) in August, respectively. Diurnal variation of the nitrification activity was correlated with water temperature(r=0.537, p〈0.05), ammonia-N(r=0.379, p〈0.05) and chlorophyll-a(r=0.399, p〈0.05), respectively.
