“…The ability of some microorganisms to use, degrade and remove heavy metals from the environment is being used, together with methods of immobilization of the microorganisms on biofilms on a suitable support in bioreactors. For example, biofilms of bacteria such as Pseudomonas putida or Chromobacterium violaceum have been used for the biodegradation of pesticides such as cypermethrin, with a biodegradation of up to 90% [ 69 , 70 ].…”

Augmenting bacterial growth is of great interest to the biotechnological industry. Hence, the effect of poly (caprolactone) fibrous scaffolds to promote the growth of different bacterial strains of biological and industrial interest was evaluated. Furthermore, different types of carbon (glucose, fructose, lactose and galactose) and nitrogen sources (yeast extract, glycine, peptone and urea) were added to the scaffold to determinate their influence in bacterial growth. Bacterial growth was observed by scanning electron microscopy; thermal characteristics were also evaluated; bacterial cell growth was measured by ultraviolet-visible spectrophotometry at 600-nm. Fibers produced have an average diameter between 313 to 766 nm, with 44% superficial porosity of the scaffolds, a glass transition around ~64 °C and a critical temperature of ~338 °C. The fibrous scaffold increased the cell growth of Escherichia coli by 23% at 72 h, while Pseudomonas aeruginosa and Staphylococcus aureus increased by 36% and 95% respectively at 48 h, when compared to the normal growth of their respective bacterial cultures. However, no significant difference in bacterial growth between the scaffolds and the casted films could be observed. Cell growth depended on a combination of several factors: type of bacteria, carbon or nitrogen sources, casted films or 3D scaffolds. Microscopy showed traces of a biofilm formation around 3 h in culture of P. aeruginosa. Water bioremediation studies showed that P. aeruginosa on poly (caprolactone)/Glucose fibers was effective in removing 87% of chromium in 8 h.

“…The applicability and benefits that the use of biofilms can have on different fields of bioremediation, due to their resistance and versatility, increases the need to research them, as well as to know them in their fields of action in order to provide favorable solutions to current environmental problems [ 69 , 70 ].…”

“…In aquatic environments, natural biofilms have the capacity to accumulate and transform a wide variety of contaminants including metals, pesticides and PhC (Achermann et al, 2019; Aubertheau et al, 2017; Bonnineau et al, 2020; Huerta et al, 2016; Mahler et al, 2020; Santos et al, 2019; Tien et al, 2013). This feature turns them into potential natural integrative samplers, useful for the detection of pollution hotspots (Aubertheau et al, 2017; Camotti Bastos et al, 2018; Fernandes et al, 2020; Rheinheimer dos Santos et al, 2020). Camotti Bastos et al (2018) have shown that biofilms and POCIS can be used as complementary techniques for the identification of anthropogenic contamination.…”

Pharmaceutical compounds (PhC) are an important environmental issue, because of their high variety, potentially toxic byproducts and bioactivity at low concentrations. PhC concentrations in WWTP effluents often exhibit large and rapid variations that are difficult to record. Passive samplers are helpful to incorporate spot pollution events and register PhC occurrence at low concentrations. In this work, we aim at (i) studying PhC accumulation in polar organic chemical integrative samplers (POCIS) and environmental biofilms exposed to urban (U) and hospital (H) treated effluents and (ii) evaluating the capacity of POCIS to predict changes in biofilm microbiome over a defined time period. Moreover, we (iii) determine the enrichment of PhC in the recipient river to evaluate levels of environmental contamination and potential effects on microbial biofilms. Biofilms and POCIS were installed in treated effluents and in the recipient river to measure the accumulation of PhC. In parallel, microbial biofilm communities were studied using DNA metabarcoding. The duration of each deployment was one month and the experiment was repeated six times. The performance of POCIS and biofilms to quantify PhC was depending on the compound. POCIS appeared well adapted to reveal contamination trends similar to these in the water column and to identify key PhC drivers of microbial changes. POCIS have the potential to predict pharmaceutical effects on biofilm community structure.

“…Periphyton form the base of the aquatic food web by acting as a fundamental dietary component for fish, tadpoles, and invertebrates (Battin et al, 2016). The heterogeneous composition of periphyton, their various sorption mechanisms (surface charges), and exchange sites in the extracellular polymeric substance matrix can cause them to accumulate a wide range of pesticides (Fernandes et al, 2020; Mahler et al, 2020; Rheinheimer dos Santos et al, 2018). Their nonspecific sorption allows a wide range of pesticides to be accumulated into the periphyton matrix even when concentrations in the surrounding water are low (Fernandes et al, 2020; Rheinheimer dos Santos et al, 2018).…”

Residual concentrations of pesticides are commonly found outside the intended area of application in Ontario's surface waters. Periphyton are a vital dietary component for grazing organisms in aquatic ecosystems but can also accumulate substantial levels of pesticides from the surrounding water. Consequently, grazing aquatic organisms are likely subjected to pesticide exposure through the consumption of pesticide‐contaminated periphyton. The objectives of the present study were to determine if pesticides partition into periphyton in riverine environments across southern Ontario and, if so, to determine the toxicity of pesticides in periphyton when fed to the grazing mayfly Neocloeon triangulifer. Sites with low, medium, and high pesticide exposure based on historic water quality monitoring data were selected to incorporate a pesticide exposure gradient into the study design. Artificial substrate samplers were utilized to colonize periphyton in situ, which were then analyzed for the presence of approximately 500 pesticides. The results demonstrate that periphyton are capable of accumulating pesticides in agricultural streams. A novel 7‐day toxicity test method was created to investigate the effects of pesticides partitioned into periphyton when fed to N. triangulifer. Periphyton collected from the field sites were fed to N. triangulifer and survival and biomass production recorded. Survival and biomass production significantly decreased when fed periphyton colonized in streams with catchments dominated by agricultural land use (p < 0.05). However, the relationship between pesticide concentration and survival or biomass production was not consistent. Using field‐colonized periphyton allowed us to assess the dietary toxicity of environmentally relevant concentrations of pesticide mixtures; however, nutrition and taxonomic composition of the periphyton may vary between sites.
