To evaluate the effect of microorganism adherent carrier for Nitzschia palea on the control of Cyanobacterial blooms, the changes of phytoplankton population structure and the chlorophyll a concentration after carrier installation were compared with those without carrier installation in field and laboratory experiments. The results showed that the installation of the carrier could control the growth of Microcystis spp., effectively. In the field investigation, the cell number of Microcystis spp. can decrease to 54,800 cells/mL after 5 d treatment comparing to 464,000 cells/mL in water without treatment, but the installation of adherent carrier did not influence the growth of other phytoplanktons including Chlorophyta. Through the observation by a microscope, the adhesion of the Nitzschia palea to this carrier was observed as well as the gliding movement of the Nitzschia palea onto the colonies of Microcystis, indicating that the adhesion, invasion and sliding movement of Nitzschia palea induced the physical destruction and effective control of Microcystis colony. Overall, the installation of this carrier can promote the growth of Nitzschia palea near carrier fiber, and control cyanobacterial blooms by the invasion of Nitzschia palea onto Microcystis colony, which can be used as one of energy-saving and sustainable eco-engineered blue-grass control methods in closed water areas such as lakes and reservoirs.
