| 中文摘要 | Variations in kinetics of alkaline phosphatase occurring in different sites of sediment associated with cage culture of Oreochromis niloticus in a shallow Chinese freshwater lake (Lake Donghu) were described. In addition, the kinetic parameters of each 2.5-cm stratum in the sediment from the surface down to 37.5 cm were analyzed. Horizontally, the V-max values of alkaline phosphatase in surface sediments increased markedly at sites immediately under and adjacent to the cage that would be subjected to the deposition of fish feces. Peak V-max values in the top 5 cm of the sediment under the cage were also observed relative to their deeper control. After a treatment where the fish feces were added over 12 days, the sediment in deeper layer exhibited a significantly higher V-max value, thereby corroborating the relationship between V-max values of alkaline phosphatase and fish feces in sediments. The fish feces exhibited a remarkable alkaline phosphatase activity (APA). Thus, it is indeed a source of the enzyme. Effects of the fish feces were dose- and time-dependent. The V-max values in sediments were always stimulated, but the K-m values showed much more variability. (C) 2001 Elsevier Science B.V. All rights reserved. |
