“…To reduce the environmental effect of synthetic dyes, a range of strategies for removing them from water and wastewater have been developed. The technologies include chemical precipitation, chemical oxidation, adsorption, decolorization by photocatalysis and/or oxidation processes [20,21], microbiological or enzymatic degradation, and so on [24,25].…”

Human needs have led to the development of various products which are produced in the industries. These industries in turn have become a source of various environmental concerns. As industries release regulated and unregulated contaminants into the water bodies, it has become a serious concern for all living organisms. Various emerging contaminates from industries like pesticides, pharmaceuticals drugs like hormones, antibiotics, dyes, etc., along with byproducts and new complexes contaminate the water bodies. Numerous traditional approaches have been utilized for the treatment of these pollutants; however, these technologies are not efficient in most cases as the contaminants are mixed with complex structures or as new substances. Advanced technologies such as bioreactor techniques, advanced oxidation processes, and so on have been used for the treatment of industrial wastewater and have served as an alternative way for wastewater treatment. Overall, biological treatment techniques based on bioreactors provide a long-term and ecologically useful solution to industrial wastewater contamination. They play an important role in saving water resources and encouraging a greener sustainable future for mankind. The current review outlines the industrial effluents that are released into water bodies, contaminating them, as well as the numerous traditional and novel treatment procedures used for industrial wastewater treatment.

“…Pseudomonas aeruginosa was isolated from Mariout Lake in Alexandria, Egypt, and used to remove Cd 2+ , Fe 3+ , Cu 2+ , Mn 2+ , Co 2+ , Zn 2+ , Ni 2+ , and Pb 2+ [24]. They fabricated a fixed bed glass bioreactor packed with a solid support luffa bulb and observed the removal of metal ions in the wastewater samples.…”

“…About 80% for Cu(II), 98% for Pb(II), 50% for Ni(II) and 77% for Zn(II) bioremediation was found to be achieved in a Membrane bioreactor (MBR) system (Katsou et al, 2011). It was found that the fixed bed bioreactors was able to increase the efficiency towards the removal of metals (Cu 2+ , Pb 2+ , Cd 2+ , Co 2+ , Ni 2+ , Zn 2+ , Mn 2+ , and Fe 3+ ) in polluted environmental samples by a strain of Pseudomonas aeruginosa to control many harmful health hazard substances (Ibrahim et al, 2019). On the other hand, removal of heavy metals including nickel, arsenic, cadmium, antimony and lead by membrane bioreactor was investigated by Komesli (2014).…”

Enhanced population growth, rapid industrialization, urbanization and hazardous industrial practices have resulted in the development of environmental pollution in the past few decades. Heavy metals are one of those pollutants that are related to environmental and public health concerns based on their toxicity. Effective bioremediation may be accomplished through “ex situ” and “in situ” processes, based on the type and concentration of pollutants, characteristics of the site but is not limited to cost. The recent developments in artificial neural network and microbial gene editing help to improve “in situ” bioremediation of heavy metals from the polluted sites. Multi-omics approaches are adopted for the effective removal of heavy metals by various indigenous microbes. This overview introspects two major bioremediation techniques, their principles, limitations and advantages, and the new aspects of nanobiotechnology, computational biology and DNA technology to improve the scenario.

“…The biogeochemical cycle that occurs in the marine environment with the diversity of existing ecosystems causes the ocean to have a natural ability to maintain its balance, including detoxifying the toxic nature of toxic components that enter marine waters [8], [9]. Thus, the quality of marine biological wealth can be massively maintained and will continue to support the sustainability of human life [10].…”

Heavy metals, mercury, and nickel are toxic contaminants, forming positive ions when concentrated and dissolved, and can accumulate in a specific object, including water. The activity and performance of bacterial bioremediation against toxic heavy metals vary due to bacterial characteristics and internal contaminant factors. This research aims to analyze the activity, performance, and efficiency of bioremediation of nickel and mercury pollutants using marine sponge symbiont bacteria. The bioremediation analysis procedure, suspension of bacteria Alcaligenes faecalis strain Cu4-1 (AF), and Acinetobacter calcoaceticus strain PHCDB14 (AC) interacted with heavy metal pollutants as contaminants for 15 days. Bioremediation performance and efficiency were measured using AAS. The analysis parameters consisted of the performance, efficiency, and mechanism of bacterial bioremediation against nickel and mercury pollutants. The research results show that the bioremediation performance of AF and AC bacteria can carry out the bioremediation function against Ni +2 and Hg +2 contaminants. The bioremediation performance of AF bacteria against Ni +2 pollutant is, on average 167.64±0.9 mg/L, equivalent to 66.85% bioremediation efficiency, and against Hg +2 an average 171.55±0.7 equivalent to the efficiency of 65.47%. The performance of bioremediation of AC bacteria on Ni +2 pollutant was 168.92±0.7 or efficiency reached 66.97%, and 145.87±0.8 for Hg +2, equivalent to 58.35% efficiency. The bioremediation performance of AF ˂ AC bacteria against Ni +2 pollutants, but against Hg +2 pollutants, the bioremediation performance of AF ˃ AC bacteria. The symbiotic bacteria of marine sponges are thought to have bioremediation performance against toxic metal pollutants are bacteria isolated from sponges whose body surface is covered with mucus substances.
