Abstract Microcystin (MC) -producing and non-MC-producing Microcystis strains typically coexist in Microcystis -dominated blooms. However, the interaction between submerged plants and Microcystis at strain level is not clear. This study aimed to assess the effects of a submerged macrophyte Myriophyllum spicatum on one MC-producing versus one non- MC-producing strains of the cyanobacterium Microcystis using plant- Microcystis co-culture experiments. The impacts of Microcystis on M. spicatum were also examined. It showed that the MC-producing Microcystis strain had a higher resistance to negative impacts by the cocultured submerged plant M. spicatum than the non-MC-producing strain. By contrast, the plant M. spicatum was impacted more by the MC-producing Microcystis than the non-MC-producer. The associated bacterioplankton community was affected more by the MC-producing Microcystis than the cocultured M. spicatum . The MC cell quotas were significantly higher in the coculture treatment (the PM+ treatment, p < 0.05), indicating that the production and release of MCs might be a key factor responsible for the reduced impact of M. spicatum . The higher concentrations of dissolved organic and reducing inorganic compounds might eventually exacerbate the recovering capacity of co-existing submerged plants. Overall, this study indicated that the capacity to produce MCs, as well as the density of Microcystis should be taken into account when attempting to re-establish submerged vegetation to undertake remediation works.

With the development of membrane separation technology, some traditional separation and purification methods have been replaced by membrane technology. Compared to traditional method, the membrane method has the advantages of small footprint, low energy consumption, safe operation and high removal rate. At present, membrane degassing has become a crucial step in ultra-pure water production for semiconductor industries, and it is also used in ink bubble removal and various wastewater treatment. This paper summarizes the advantages of membrane degassing compared with other gas-liquid separation methods, and introduces polymeric membrane materials used for degassing and their merits and drawbacks. The greatest challenge encountered in membrane degassing is the resistance to wetting phenomenon. This paper provides solutions to wetting phenomenon, which increases the possibility of widespread application of membrane degassing technology and the adaptability of membrane degassing technology to more demanding use scenarios. Finally, the application scenarios of membrane degassing technology are summarized and future prespectives are provided.
