Special Issue Information

Dear Colleagues,

Industrial development, unplanned urbanization, and rapid population growth have led to serious environment and human health concerns. Among the various factors, discharge from industries plays a key role in polluting water bodies, which reduces the already limited drinking water sources of an ever-growing population. Such unplanned industrial discharge further leads to soil pollution and contamination of the ground water table. Hence, with the ever-growing public concern about the environment and stringent governmental regulations, it is necessary to explore novel technologies to treat such wastewater. Biological treatment technologies and/or nature-based solutions involving microorganisms or plants are considered a low-cost, sustainable, and environment-friendly method for treating industrial effluents and restoring polluted land. Furthermore, biological treatment provides options for resource recovery from wastes in the form of biomass, bioenergy, and commercially important bioproducts. The zero liquid discharge goal could be achieved with advanced membrane technologies. Another model that has attracted a lot of attention recently is the waste-fed biorefinery concept, in which a wide range of products are obtained from waste using biochemical routes. Therefore, the key focus in this area of research currently is sustainable pollution mitigation using biological methods toward achieving a circular economy.

In this regard, the present Special Issue will highlight relevant topics such as recent innovation in bioremediation and phytoremediation of industrial effluents, biological soil remediation technologies, biological treatment of solid wastes, application of advanced technologies such as genetic engineering, nanotechnology, and membrane technology approach for process improvement, biological valorization of waste for production of bioenergy, and value-added products.

Biochar-Assisted Bioengineered Strategies for Metal Removal: Mechanisms, Key Considerations, and Perspectives for the Treatment of Solid and Liquid Matrixes

Biochar has drawn the scientific community’s attention during the last few years due to its low production value and unique physicochemical properties, which are helpful for numerous applications. The development of biotechnological processes for the remediation of heavy metal environmental pollution is one central research avenue in which biochar application has shown promising results, due to its positive effect on the bacteria that catalyze these activities. Biochar stimulates bacterial activity through adsorption, adhesion, electron transport, and ion exchange. However, before biochar implementation, a complete understanding of its potential effects is necessary, considering that those interactions between biochar and bacteria may help improve the performance of biological processes designed for the remediation of environmental pollution by metals, which has been historically characterized by limitations related to the recalcitrance and toxicity of these pollutants. In this review, the key biochar–microorganism interactions and properties of unmodified biochar with the potential to improve metal bioremediation in both solid (mine tailings, polluted soils) and liquid matrixes (metal-laden wastewaters) are summarized. Knowledge gaps regarding the mechanisms involved in remediation strategies, the effect of long-term biochar use and the development of improved biochar technologies and their combination with existent remediation technologies is summarized. Additionally, an up-to-date summary of the development of biochar-assisted bioengineered strategies for metal passivation or removal from solid and liquid matrixes is presented, along with key perspectives for the application of biochar-based biotechnologies at full scale during the treatment of mining effluents in the real scale.

Despite the continuous enforcement of Antarctic Treaty System, ATS (1961), today Antarctica is constantly plagued by hydrocarbon pollution from both legacy and present-day wastes, especially near where anthropogenic activities are the most intense. The advances of science have led to multiple breakthroughs to bolster bioremediation techniques and revamp existing laws that prevent or limit the extent of hydrocarbon pollution in Antarctica. This review serves as the extension of collective efforts by the Antarctic communities through visual representation that summarizes decades of findings (circa 2000–2020) from various fields, pertinent to the application of microbe-mediated hydrocarbons remediation. A scientometric analysis was carried out based on indexed, scientific repositories (ScienceDirect and Scopus), encompassing various parameters, including but not limited to keywords co-occurrences, contributing countries, trends and current breakthroughs in polar researches. The emergence of keywords such as bioremediation, biosurfactants, petroleum hydrocarbons, biodiesel, metagenomics and Antarctic treaty policy portrays the dynamic shifts in Antarctic affairs during the last decades, which initially focused on exploration and resources exploitation before switching to scientific research and the more recent ecotourism. This review also presents the hydrocarbonoclastic microbes studied in the past, known and proposed metabolic pathways and genes related to hydrocarbon biodegradation as well as bacterial adaptations to low-temperature condition.
