“…Yanbo et al (2021) concluded that adding co-metabolizing substances can improve the COD removal rate of coking wastewater as a result of the promoted growth of bacteria involved in the biodegradation of refractory organic wastewater. They observed that the COD removal rate increased by 1.87% with the addition of glucose as the co-metabolism matrix compared to the control system (Yanbo et al , 2021).…”

Purpose This paper aims to study the application of high-tolerance and flexible indigenous bacteria and fungi, along with the co-metabolism in recycled paper and cardboard mill (RPCM) wastewater treatment (WWT). Design/methodology/approach The molecular characterization of isolated indigenous bacteria and fungi was performed by 16S rRNA and 18S rRNA gene sequencing, respectively. Glucose was used as a cometabolic substrate to enhance the bioremediation process. Findings The highest removal efficiency was achieved for both chemical oxygen demand (COD) and color [78% COD and 45% color removal by Pseudomonas aeruginosa RW-2 (MZ603673), as well as approximately 70% COD and 48% color removal by Geotrichum candidum RW-4 (ON024394)]. The corresponding percentages were higher in comparison with the efficiency obtained from the oxidation ditch unit in the full-scale RPCM WWT plant. Originality/value Indigenous P. aeruginosa RW-2 and G. candidum RW-4 demonstrated effective capability in RPCM WWT despite the highly toxic and low biodegradable nature, especially with the assistance of glucose.

“…To reduce the still existing environmental problems concerning phenol pollution worldwide, new and innovative strategies are constantly developed and tested under laboratory conditions before their application in practice on a technical scale. Among these strategies, bioaugmentation using the natural ability of microorganisms (bacteria or fungi) to decompose phenolic compounds is widely and successfully applied in the recultivation of phenol-contaminated soil and wastewater [10,47,48]. However, not all microorganisms that can degrade phenol and its derivatives in the established optimal laboratory conditions can be introduced into contaminated sites to enhance the degradation potential of the indigenous microbiome.…”

Despite the well-described abundance of phenol-degrading bacteria, knowledge concerning their degradation abilities under suboptimal conditions is still very limited and needs to be expanded. Therefore, this work aimed to study the growth and degradation potential of Stenotrophomonas maltophilia KB2 and Pseudomonas moorei KB4 strains toward phenol under suboptimal temperatures, pH, and salinity in connection with the activity of catechol dioxygenases, fatty acid profiling, and membrane permeability. The methodology used included: batch culture of bacteria in minimal medium supplemented with phenol (300 mg/L), isolating and measuring the activity of catechol 1,2- and 2,3-dioxygenases, calculating kinetic parameters, chromatographic analysis of fatty acid methyl esters (FAMEs) and determining the membrane permeability. It was established that the time of phenol utilisation by both strains under high temperatures (39 and 40 °C) proceeded 10 hours; however, at the lowest temperature (10 °C), it was extended to 72 hours. P. moorei KB4 was more sensitive to pH (6.5 and 8.5) than S. maltophilia KB2 and degraded phenol 5–6 hours longer. Salinity also influenced the time of phenol removal. S. maltophilia KB2 degraded phenol in the presence of 2.5% NaCl within 28 hours, while P. moorei KB4 during 72 hours. The ability of bacteria to degrade phenol in suboptimal conditions was coupled with a relatively high activity of catechol 1,2- and/or 2,3-dioxygenases. FAME profiling and membrane permeability measurements indicated crucial alterations in bacterial membrane properties during phenol degradation leading predominantly to an increase in fatty acid saturation and membrane permeability. The obtained results offer hope for the potential use of both strains in environmental microbiology and biotechnology applications.

The global population is increasing at an elevated speed leading to the expansion of urbanization at the cost of environmental degradation, especially aquatic ecosystem pollution due to the enhanced discharge of wastewater. These aquatic ecosystems are primarily polluted by potentially toxic elements, polyaromatic hydrocarbons, dyes, plastics, pesticides, organic compounds, and molecules present in fertilizers, household wastes, industrial effluents, and sewage discharge. The enhanced deterioration of water bodies has led to the search for natural solutions for a sustainable ecosystem. The utilization of the natural microbial flora of the aquatic ecosystem for remediation, more popularly known as bioremediation, is of global interest because of its cost‐effectiveness and eco‐friendly approach. Bioremediation can be broadly categorized into bacterial remediation, mycoremediation, and phytoremediation and is more commonly studied for soil pollution. However, in this review, we discuss bioremediation techniques and mechanisms with respect to water pollution. Aquatic microbes utilize the toxic components present in wastewater as a substrate for their own metabolism by acting as a biologically active methylator or by chemical alteration of the toxicants into less harmful products, thus degrading the toxic environmental pollutants into nontoxic products thereby eliminating their detrimental effects. Microalgae used in phytoremediation also help to elevate the dissolved oxygen level in the aquatic ecosystem thereby reducing the probability of eutrophication. This review represents the study of diverse pollutants remediation and a method involving microbial consortia in a bioreactor for optimum efficacy at minimum cost.
