Recent advances biodegradation and biosorption of organic compounds from wastewater: microalgae-bacteria consortium-A review
Abstract
The litter of persistent organic pollutants (POPs) into the water streams and soil bodies via industrial effluents led to several adverse effects on the environment, health, and ecosystem. For the past decades, scientists have been paying efforts in the innovation and development of POPs removal from wastewater treatment. However, the conventional methods used for the removal of POPs from wastewater are costly and could lead to secondary pollution including soil and water bodies pollution. In recent, the utilization of green mechanisms such as biosorption, bioaccumulation and biodegradation has drawn attention and prelude the potential of green technology globally. Microalgae-bacteria consortia have emerged to be one of the latent wastewater treatment systems. The synergistic interactions between microalgae and bacteria could proficiently enhance the existing biological wastewater treatment system. This paper will critically review the comparison of conventional and recent advanced wastewater treatment systems and the mechanisms of the microalgae-bacteria symbiosis system.

The three mechanisms of biosorption, bioaccumulation, and biodegradation can occur together in microalgal wastewater treatment: biodegraded particles can be adsorbed on the microalgal surface, then transferred into cells by active processes, and enzymatic reactions promote precipitation, biotransformation, and bioaccumulation inside the cells.
“Generally, it has been reported that the three mechanisms can go hand by hand in microalgal WWT as biodegraded particles can be adsorbed on their surface, followed by the transfer of particles into the cells by active processes. Eventually, enzymatic reactions promote precipitation, biotransformation, and bioaccumulation inside the cells [62].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
