The role of free and attached microorganisms in the decomposition of estuarine macrophyte detritus
(2003) In Estuarine, Coastal and Shelf Science 56(2). p.197-201- Abstract
- Abundance and respiration of free and attached microorganisms were monitored during the decomposition of the seagrass Scirpus maritimus leaves in laboratory microcosms for 30 days. There was a clear succession between bacteria and heterotrophic flagellates during the course of the study. The beginning of the study (1-4 days) was characterized by higher rates of bacterial respiration, compared to the later periods. Free microorganisms were responsible for more than half of the respiration (65%) within the microcosms, suggesting that they were responsible for the mineralization of the bulk of the macrophyte detritus following its dissolution. On the other hand, estimates of activity on a per cell basis revealed that individual attached... (More)

On the other hand, estimates of activity on a per cell basis revealed that individual attached bacteria had much higher (3- to 4-fold) respiration rates than free bacteria, suggesting attached bacterial activity may play a key role in the breakdown and dissolution of particulate detritus in estuarine waters. The findings suggest different but coupled roles for attached and free bacteria in nature. (Less)
