| Abstract |
The effect of salts added to the natural esturine water from the estuary of Naktong river on the glucose turnover rate, respiration rate, and the total populations of the microorganisms were determined. At station 1, the turnover rate for glucose of the microorganisms has decreased up to two days after salt addition. The added salt lost its effect in four days. However, at station 2 and 3, the turnover rates for glucose of the microorganisms were less decreased or even increased with increasing salt concentrations. Again, no differences were noticed in four and seven days at stations 2 and 3, each respectively. The respiration rates showed increasing tendency with increasing salt concentrations at there stations. Added salts caused no noticeable changes in total bacterial numbers and viable counts during the testing period. |
