“…In addition to the production of certain species of microalgae in open raceways, zebra mussels may have utility in the production of commercially relevant filamentous macroalgal species. Lawton et al ., (2017) identify the cosmopolitan freshwater macroalgae genus Oedogonium as an ideal candidate for open pond systems, as it is resilient, competitively dominant and has biomass productivities comparable with microalgae 44 . Sakharova et al ., (2018) have illustrated that Oedogonium is resistant to the grazing of zebra mussels 45 and so therefore a coculture system in which zebra mussels remove competing microalgae species, reducing competition for light and nutrients, may help to improve Oedogonium yields further.…”

Synthetic Ecology is a novel concept describing the design of de novo ecological communities for a designated purpose. This study is a proof of concept for harnessing Synthetic Ecology in expanding the scale of commercially relevant micro algae ( Chlorella vulgaris ) cultivation using stable Synthetic Ecologies in open environments as opposed to vulnerable monocultures. We focused on whether the grazing activity of zebra mussels ( Dreissena polymorpha ) would result in a consistent, and commercially favourable, dominance of Chlorella in cultures that were also inoculated with a competing and potentially invasive cyanobacteria ( Synechocystis sp. PCC6803 ). The key result of this study was that in axenic mixed species co-cultures, zebra mussels had a significantly greater negative effect on Synechocystis cell numbers than Chlorella (P < 0.0001). The zebra mussels’ putative preference for Synechocystis over Chlorella suggests they could be used to maintain the dominance of Chlorella in outdoor cultivation systems prone to contamination by invasive cyanobacteria.

“…Furthermore, after lipid extraction the biomass feedstock can be converted into algae biochar by conventional pyrolysis [160], torrefaction or hydrothermal carbonization. Algae biochar represent a new class of efficient fertilizers and absorbent materials for toxicants [161]. A combination with other sorbent material i.e., chitosan can enhance the application of bio char for treating the sewage wastewater prior to irrigate the agricultural fields.…”

Electro-Microbiology as a Promising Approach Towards Renewable Energy and Environmental Sustainability

Microbial electrochemical technologies provide sustainable wastewater treatment and energy production. Despite significant improvements in the power output of microbial fuel cells (MFCs), this technology is still far from practical applications. Extracting electrical energy and harvesting valuable products by electroactive bacteria (EAB) in bioelectrochemical systems (BESs) has emerged as an innovative approach to address energy and environmental challenges. Thus, maximizing power output and resource recovery is highly desirable for sustainable systems. Insights into the electrode-microbe interactions may help to optimize the performance of BESs for envisioned applications, and further validation by bioelectrochemical techniques is a prerequisite to completely understand the electro-microbiology. This review summarizes various extracellular electron transfer mechanisms involved in BESs. The significant role of characterization techniques in the advancement of the electro-microbiology field is discussed. Finally, diverse applications of BESs, such as resource recovery, and contributions to the pursuit of a more sustainable society are also highlighted.
