Carbon Flux Through Bacteria in a Eutrophic Tropical Environment: Port Klang Waters

6. Conclusion

Port Klang waters is eutrophic and long term data showed that its water quality is deteriorating. We observed the occurrence of hypoxia due to very low GPP that was limited by NO3. Although primary production is the basis of aquatic food web, and supported both CR and BCD, episodes of uncoupling were observed. Uncoupling occurred especially when GPP was very low, and generally BCD and GPP were balanced. Our results showed that only 2% of C consumed by bacteria were passed onto protists. This suggested that the microbial loop was not an efficient pathway to recycle organic matter as a substantial amount of carbon was lost.
