Article Synopsis
- Cyanobacterial harmful algal blooms (CyanoHABs) pose risks to public health and freshwater ecosystems, prompting a study on their dynamics and the movement of microcystins (MCs) from Lalla Takerkoust reservoir to nearby farms.
- The research identified Microcystis and Synechococcus species as responsible for the blooms, with Microcystis producing significant levels of three MC variants, particularly MC-RR, while Synechococcus showed no toxin production.
- Analysis revealed a historical pattern of cyanobacterial proliferation and indicated a significant decrease in MC concentrations as one moves downstream from the reservoir, emphasizing the influence of environmental factors and the necessity for effective bloom management.
Article Synopsis
- Eutrophication has caused toxic cyanobacterial blooms in the Lalla Takerkoust reservoir in Morocco, prompting a study to assess the effectiveness of Multi-Soil-Layering (MSL) ecotechnology in removing these blooms.
- Two MSL setups using different types of soil (sandy for MSL1 and clayey for MSL2) were tested, significantly lowering cyanobacterial concentrations and eliminating organic matter levels by over 95%.
- MSL1 demonstrated improved microcystin (MC) removal from 52% to 99%, while MSL2 began at 90% reduction but fluctuated before stabilizing at 86%, indicating both systems effectively tackle cyanobacterial contamination.
Microcystins (MCs) constitute a significant threat to human and environmental health, urging the development of effective removal methods for these toxins. In this review, we explore the potential of MC-degrading bacteria as a solution for the removal of MCs from water. The review insights into the mechanisms of action employed by these bacteria, elucidating their ability to degrade and thus remove MCs.
