“…Additionally, extracellular polymeric substances (EPS) can be produced by algae and bacteria, which are mostly polysaccharides, proteins, nucleic acids, and lipids (Flemming and Wingender 2010). These chemical components provide important sites for the sorption of heavy metals and organic contaminants (Fomina and Gadd 2014;Wang and Chen 2009). Sorption of organic contaminants is highly dependent on their physical-chemical properties.…”

Pharmaceuticals and personal care products (PPCPs) consist of a variety of compounds extensively used for the treatment of human and animal diseases and for health or cosmetic reasons. PPCPs are considered as emerging environmental contaminants due to their ubiquitous presence in the environment and high environmental risks. In wastewater treatment plants using conventional activated sludge processes, many PPCPs cannot be efficiently removed. Therefore, there is an increasing need for more effective and cost-efficiency ways of removing PPCPs while treating wastewater. Algae-based technologies have recently attracted growing attentions for their potential application in wastewater treatment and hazardous contaminant removal, which are advantages in reducing operation cost while generating valuable products and sequestrating greenhouse gases at the same time. This work reviews the up-to date researches to reveal potential toxic effects of PPCPs on algae and algae-bacteria consortia, identify mechanisms involved in PPCP removal, and assess the fate of PPCPs in algae-based treatment systems. Current researches suggest that algae and algae-bacteria consortia have great potentials in PPCP removal but more works are required before algae-based technologies can be implemented in large scales. Knowledge gaps are identified and further research focuses are proposed in this review.

“…In addition, this process has many advantages such as those metals (K + , Mg + ) that are highly mobile and don't get accumulated with biomass during phytoremediation which can be easily removed through biosorption. Eradication of heavy metals along with dyes, phenolic compounds and pesticides is receiving lot of attention through this process (Fomina and Gadd 2014).…”

Adsorptive removal of lead and arsenic from aqueous solution using soya bean as a novel biosorbent: equilibrium isotherm and thermal stability studies

In this study, adsorption potential of soya bean adsorbent for lead (Pb) and arsenic (As) has been assessed in order to consider its suitability for purification of wastewater containing heavy metals. The main focus of study was on Pb and As. Batch experiments were performed to study the adsorption of Pb and As on soya bean absorbent. The effect of various experimental parameters (adsorbent dose, contact time, temperature and pH) was studied, and optimal conditions were determined. The effect of adsorbent dose on the biosorption of Pb and As from aqueous solution was studied at 37 °C by varying the adsorbent amount from 1 g/100 ml to 4 g/100 ml. Highest amount of Pb and As was adsorbed at sorbent amount of 3 g/100 ml. The optimum pH for removal of As and Pb was found to be 2.0 and 4.0 ± 0.26. Maximum biosorption of Pb and As was achieved at 37 °C. The maximum percentage removal of Pb and As was attained at 60 min of shaking time. Langmuir and Freundlich isotherm models were utilized for equilibrium studies. It was found that biosorption by soya bean adsorbent was exothermic in nature. The thermal degradation analysis suggested that the degradation occurs in two steps and adsorbent is thermally stable.Keywords Biosorption · Soya bean adsorbent · Lead and arsenic · Sorption isotherm and thermal analysis of biosorbent

“…In order to improve adsorption processes, the use of fungal biomass has been receiving great attention because of its variety and versatility. The microorganisms in general can accumulate or transform xenobiotics, as a result of specific enzymatic reactions or mechanisms resulting in the characteristics and properties of the cell wall and the plasma membrane [16].…”
