N2O is an important greenhouse gas that also damages the ozone layer.N2O emissions have been observed during microalgae cultivation and in microalgae-based ecosystems,such as eutrophic lakes.However,little has been reported on the important role of the N2O balance in algae and the potential algal N2O production pathways.A review of recent relevant studies on N2O synthesis and fixation by algae shows that the studies mainly focus on the relationship between algae and N2O emissions,several possible pathways of N2O production and consumption in algae,the influence of the algal microenvironment on the distribution pattern of N2O,and the potential impacts on global climate change.However,the Intergovernmental Panel on Climate Change currently does not consider the possible N2O emissions during algal blooms or algal aquaculture;hence,it is necessary to intensify experimental studies related to algal N2O production globally to take important steps towards a comprehensive clarification of the important roles of algae in N2O emission and fixation and a comprehensive assessment of greenhouse gas emissions from aquatic ecosystems.
