Summary: The study proposed an advanced microalgae-based process for treating sugarcane spent wash, recovering biomass for biodiesel production, and utilizing algal residue as a step towards waste management. The microalgae Coelastrella sp KJ-04 grown in spent wash showed high biomass and lipid production. The extracted lipids were converted to biodiesel and the de-oiled biomass was used to synthesize cellulose nanofibers, supporting a waste-free technology.

Summary: In this study, a microalgae-bacteria symbiosis (ABS) system was developed for pollutants removal by co-culturing Chlorella sorokiniana with activated sludge, and the interaction mechanism was investigated. The ABS system achieved almost complete removal of ammonia nitrogen, with removal efficiencies of 65.3% for total nitrogen and 42.6% for total phosphorus. Brevundimonas greatly promoted microalgal biomass growth and microalgae contributed to the increase in the abundance of Dokdonella and Thermomonas, facilitating nitrogen removal. The study also identified key extracellular polymeric substances for the formation of flocs by microalgae and activated sludge.

Summary: Urbanization, industrialization and other human-related activities contribute to the discharge of toxic substances into the environment. The use of algae in wastewater treatment has been widely studied and it has been found that algae consortium systems are more effective than monocultures. Microorganisms such as bacteria or fungi in wastewater can form symbiotic relationships with algae, aiding in the removal of pollutants. This review explores the symbiotic relationships between algae and other microorganisms and their applications in wastewater treatment.

Summary: Oxylipins produced by diatoms are important for structuring zooplankton communities, and in this study, the researchers found that the diatom polyunsaturated-aldehyde (DPA), also known as 2-trans,4-trans decadienal (DD), has a significant impact on the population trajectory and life table attributes of the Cladocera Echinisca triserialis. The results show that exposure to DD leads to increased mortality and decreased reproduction in E. triserialis individuals, but the F1 generation individuals produced in the presence of DD showed higher survival and reproduction rates. These findings suggest that prolonged exposure to DPA can favor preexposed genotypes within the community and that parental experience can extend to the F1 generation in diatom aldehyde-contaminated environments.
