The role that microorganisms play in the biological removal of phosphate from wastewater streams has received sustained interest since its initial observation over 30 years ago. Recent advances in 'omic'-based approaches have greatly advanced our knowledge in this field and facilitated a refinement of existing enhanced biological phosphate removal (EBPR) models, which were primarily based on culture-dependent approaches that had predominantly been used to investigate the process. This minireview will focus on the recent advances made in our overall understanding of the EBPR process resulting from the use of 'omic'-based methodologies.
