Soil contamination with phthalate esters (PAEs) is a worldwide environmental issue, and a stable and efficient functional microbial agent could be applied to achieve synergistic PAEs degradation. The review comprehensively compared various methods and pathways of microbial immobilization. The different factors on PAEs elimination such as mass transfer environment, substrate concentration, immobilization conditions, and strain combinations were demonstrated. The metabolic pathways of PAEs driven by enzymatic reactions of functional microbes were elucidated. The biological mechanisms of synergistic degradation of PAEs by microbial communities were clarified, and crucial future research areas may include the construction of microbial composite communities, optimization of immobilization carriers, and creation of microbial agent products. Compared to single-free bacteria, the immobilized PAEs-degrading microbial agents not only resist the interference of complex external environments, but specifically perform well on PAE degradation. In addition, immobilized microbial agents may positively promote crop growth.
