Abstract

In this study we used the Landry and Hassett 1982 dilution method to determine bacterial process rates bacterial production and bacterial respiration. Two different sampling stations were chosen; Klang and Port Dickson. Klang was an eutrophic estuary whereas Port Dickson was an oligotrophic coastal water system. The average temperature measured at both sites was 29.7C whereas dissolved oxygen DO was lower at Klang 148 24 M Mean Standard Deviation compared to Port Dickson 210 16 M . pH was lower in Klang and its salinity fluctuated over a wider range CV 20 compared to Port Dickson CV 15. Bacterial production measured at Klang showed wider fluctuation from 0.90 to 2.75 M C h- 1.75 0.54 M C h- whereas Port Dickson ranged from 0.15 to 1.10 M C h- 0.49 0.24 M C h-. Bacterial respiration measured at Klang was highly variable from 1.98 to 21.53 M O‚‚ h- 8.35 6.74 M O‚‚ h- whereas at Port Dickson bacterial respiration fluctuated from 1.29 to 5.35 M O‚‚ h- 2.95 1.17 M O‚‚ h-. Bacterial growth efficiency at Klang fluctuated from 0.05 to 0.37 0.21 0.12 whereas Port Dickson fluctuated from 0.08 to 0.28 0.15 0.07.
