“…These technologies that make up bioremediation are environmental friendly, might be less expensive in some cases, and cause less impact to the environment when compared to technologies that use chemical and/or physical processes [55,56] . In addition, bioremediation emerges as an alternative that may be applied both in situ (affected site) and ex situ, with bench scale tests for process optimization and subsequent in situ application.…”

Advances and perspectives in the use of polymers in the environmental area: a specific case of PBS in bioremediation

et al. 2020

View full text Add to dashboard Cite

Biodegradable polymers (e.g. poly(butylene succinate)-PBS) have been used in several sectors such as the environmental area, especially in bioremediation, in biological processes for conversion of pollutants into inorganic compounds. In this study, the foresight methodology for the use of biodegradable polymers, including PBS, reveals a publication rate of approximately 8.74 articles and 30.63 patents per year, between 2005 and 2019. However, the application of PBS, specifically, is still restricted to the environmental area, with only 3.0% of the 1484 works from this period. The results showed a more significant number of papers on the PBS application for synthesis, characterization, and application in the areas of Chemistry, Physics, and Pharmacy. In the area of bioremediation, only three studies related to PBS were found, revealing the lack of research and development to increase the contribution in the area of environmental recovery.

“…Commercial chitin and shrimp shell waste were evaluated as substrates for sulfate‐reducing bacteria (SRB) to treat AMD‐impacted water in an anaerobic reactor (Rodrigues, Nunez‐Gomez, Silveira, Lapolli, & Lobo‐Recio, 2019). It was found that the shrimp shell waste had the best removal of sulfate and metals (over 99%).…”

Drainage from current and historic mining operations remains a persistent environmental problem. Numerous research and development efforts were made in 2019 with a goal to minimize the impact of mine drainage on the environment, while other research endeavors addressed the mine drainage issue from a different perspective, where mine drainage was considered a resource for water and valuable products, such as metals, sulfuric acid, and rare earth elements. Thus, this review has two main sections: (a) focusing on research efforts in mine drainage remediation technology, and (b) emphasizing advances in resource recovery from mine drainage. The first section covers traditional and emerging passive and active treatment technologies. The second section summarizes resource recovery efforts using various technologies, such as selective precipitation, membrane process, and biological systems.

“…Several enzymes are involved in this sulfate reduction process, such as ATP-sulfurylase, adenylylsulfate reductase and dissimilatory sul te reductase. In addition to this, the reduction of sulfate to sulfur can be divided into several steps: ATP-sulfurylase drives the activation of sulfate into APS; adenosine 5′-phosphosulfate reductase (AprAB) catalyzes the transformation of APS to sul te; the dissimilatory sul te reductase (DrsAB) promotes the conversion of sul te to sul de (Li et al 2019a, Rodrigues et al 2019. The drsAB gene which encodes the DrsAB, had widely detected a range of SRB community structures, containing more than 20 different genera, such as Desulforibrio, Desulfomonas, Desulfobulbus, Desulfobacter, Desulfococcus, Desulfosarcina, Desulfonema, Desulfotomaculum and a genus Archaeoglobus within Archaea (Guan et al 2013, Lu et al 2017.…”

Microbial sulfate reduction, a vital mechanism for microorganisms living in anaerobic, sulfate-rich environments, is an essential aspect of the sulfur biogeochemical cycle. However, there has been no detailed investigation of the diversity and distribution of SRBs and its effect in Shimen Realgar Mine, which is characterized as a hot research area rich in sulfate. To elucidate this issue, soils sample from Shimen Realgar Mine were collected. Further, a total of 55 new or new-type dissimilatory sulfite reductase genes and 5 new families of DrsAB proteins were successfully identified, which demonstrate the rich and unique diversity of the sulfate reducing microbes in this environment. We also isolate a novel DSRP strain, Desulfotomaculum sp. JL90 from the soils, which can efficiently respiratory reduces sulfate and arsenate. JL90 also can promote the generation of yellow precipitations in the presence of multiple electron acceptors (both contain sulfate and As(V) in the cultures). Moreover, microbial community compositions also indicated the biogenesis contribution of SRBs to the Shimen realgar mine. The results of this study provided a new insight into the diversity and distribution of SRBs and its ecological effect in Shimen Realgar Mine.
