Organic pollutants (OPs) discharged via wastewater can severely impact public health, natural habitat, and environment in long term. The microalgae-bacteria consortia (MBC) demonstrates its potential as a sustainable bioremediation method for organic pollutants remediation from wastewater. The overarching goal of this study is to review (i) the formation of microalgae and bacteria consortia, (ii) the mechanism of MBC in OCs removal, (iii) the effects of operating conditions on the treatment efficiency, and (iv) the omics approach of MBC for removing OCs in wastewater. The review provides further insights into the application of omics techniques to identify microalgae-bacteria interaction in the consortia. Transcriptomics and metabolomics have elucidated the response of MBC to the impact of culturing conditions and presence of OCs in wastewater. Metagenomics identifies the four dominating-algal strains and observing microbial dynamics during ciprofloxacin treatment. The data of omics approach provide a strong support for upscaling MBC for OCs remediation in wastewater. • The MBC presents in three main forms: commensalism, mutualism, and parasitism. • Short-term contact with OPs enhances protoplasmic responses of MBC cells. • Long-term contact alters the whole MBC structure. • The MBC removes OPs higher than 90 %. • Omics reveal removal mechanisms, bacterial diversity, and interaction in MBC.
