In the near future, the bio-nutrient-removal (BNR) system is no longer confined to meet the nitrogen and phosphorus removal requirement, but operated for sequestering and recovering carbon, nitrogen and phosphorus from wastewaters and generate more high-value-added by-products. Polyhydroxyalkanoate (PHA) is a metabolite of microorganisms under unfavourable growth conditions for their own energy storage and utilization. More and more researches have gradually uncovered the impacting factors on the microbial synthesis of PHA in the BNR and none-BNR system. This mini-review summarizes the impacting factors of carbon source types and dosage, nitrogen concentration and phosphorus recovery and temperature variation on the enrichment of PHA by microbial populations. Furthermore, the potential genomic reasons for promoting PHA synthesis are introduced. It provides a new perspective to stimulate the PHA synthesis by the functional microorganisms and its potential benefit for bio-nutrient...
