“…The implementation of biodegradation processes using natural samples displays some difficulties, and strategies based on natural or artificial microbial consortia could be an alternative more effective than approaches based on the isolation, purification and characterization of individual species (Massot et al, 2022), as recently reported F I G U R E 4 Application of (meta)omics and synthetic biology for cyanide and heavy metal bioremediation.…”

Cyanide is a highly toxic compound that is found in wastewaters generated from different industrial activities, such as mining or jewellery. These residues usually contain high concentrations of other toxic pollutants like arsenic and heavy metals that may form different complexes with cyanide. To develop bioremediation strategies, it is necessary to know the metabolic processes involved in the tolerance and detoxification of these pollutants, but most of the current studies are focused on the characterization of the microbial responses to each one of these environmental hazards individually, and the effect of co‐contaminated wastes on microbial metabolism has been hardly addressed. This work summarizes the main strategies developed by bacteria to alleviate the effects of cyanide, arsenic and heavy metals, analysing interactions among these toxic chemicals. Additionally, it is discussed the role of systems biology and synthetic biology as tools for the development of bioremediation strategies of complex industrial wastes and co‐contaminated sites, emphasizing the importance and progress derived from meta‐omic studies.

“…The advantage of using fungal–bacterial cross-kingdom consortia is that fungal hyphae may represent media for the bacterial colonization of soil that can facilitate the migration of bacterial strains beyond what can be accomplished individually. These studies have formed the basis for investigations into positive interactions between bacteria and fungi that have high potential for the bioremediation of plastic pollutants ( Massot et al, 2022 ). Interestingly, Lou et al (2022) and Ruiz Barrionuevo et al (2022) studied the gut microbial communities of PE-fed wax worms and their larvae suggesting that the gut microbes of invertebrates and the constructed microbial consortia are capable of consuming and degrading plastic polymers, thus providing a new resource for the development of functional microbial consortia that have the capacity to degrade PE and other types of plastics.…”

Numerous microorganisms and other invertebrates that are able to degrade polyethylene (PE) have been reported. However, studies on PE biodegradation are still limited due to its extreme stability and the lack of explicit insights into the mechanisms and efficient enzymes involved in its metabolism by microorganisms. In this review, current studies of PE biodegradation, including the fundamental stages, important microorganisms and enzymes, and functional microbial consortia, were examined. Considering the bottlenecks in the construction of PE-degrading consortia, a combination of top-down and bottom-up approaches is proposed to identify the mechanisms and metabolites of PE degradation, related enzymes, and efficient synthetic microbial consortia. In addition, the exploration of the plastisphere based on omics tools is proposed as a future principal research direction for the construction of synthetic microbial consortia for PE degradation. Combining chemical and biological upcycling processes for PE waste could be widely applied in various fields to promote a sustainable environment.

“…An effective strategy for bioremediation of acutely contaminated soils is the inoculation of allochthonous PAH-degrading microorganisms (Nwankwegu et al, 2022). The use of microbial consortia as inocula in bioremediation processes became relevant in recent times, since the interactions between their members can optimize the degradation processes (Massot et al, 2022). Positive interactions favor consortia stability and robustness, which can be correlated with consortia diversity, and increase the probability of inoculum establishment (Stenuit and Agathos, 2015; Che and Men, 2019; McCarty and Ledesma-Amaro, 2019; Ziesack et al, 2019).…”

Polycyclic aromatic hydrocarbons (PAHs) are priority pollutants. We studied the effect of 20 bioaugmentation with three allochthonous bacterial consortia with increasing diversity, SC AMBk, SC1 21 and SC4, in the structure and functionality of an acutely PAH-contaminated soil microbiome. The PAH 22 supplementation increased the resource availability and the inocula were able to: efficiently degrade 23 the PAHs supplemented after 15 days of incubation, become temporary established, and modify the 24 number of total interactions with soil residents. Sphingobium and Burkholderia, both member of 25 inoculants, were the major contributors to KO linked to degradation and to differentially abundant 26 genera in inoculated microcosms, indicating their competitiveness in the soil. Bioaugmentation 27 efficiency relayed on them, while further degradation, could be carried out by native microorganism. 28 This is the one of the first works which applied three inocula, designed from naturally occurring 29 bacteria and study their effect on the soil native community through the ANCOM-BC. We revealed that 30 when a resource that can be use by the inoculant is added to the soil, it is not necessary a high-diversity 31 inoculant to interact with native community and establish itself. This result has implications in the 32 design of microbiome engineering for bioremediation processes
