“…Globally, the top five productive countries in biodegradation-ofplastics-related research are China with the highest number of documents (n = 92), followed by the USA (n = 82), India (n = 47), Japan (n = 45), and Canada (n = 31). Though China accounts for the largest production of plastic materials globally [25,26], China still makes a significant effort to remove plastic pollution through the implementation of policies and numerous funded projects. Countries with the greatest contribution are shown in Figure 1b, where the darker the blue colour, the greater the number of documents published.…”

The rapid growth in the production and application of plastic globally has resulted in plastic pollution with a negative impact on the environment, especially the marine ecosystem. One main disadvantage in the majority of polymers is disposal after a useful life span. Non-degradable polymers create severe difficulty in plastic waste management that might end up in landfills or wash into the ocean. The biodegradation of plastic waste is one solution to this critical problem of pollution. Hence, there is a need to consider the advancement of research in this subject area, in pursuit of a way out of plastic pollution. Thus, this study was designed to map the biodegradation of plastic-related research from 2000 to 2021. Statistical information on the topic was recovered from the Web of Science Core Collection and analysed using the bibliometrix package in RStudio statistical software, while data visualisation was conducted via VOSviewer. Our evaluation indicated that the amount of research on the biodegradation of plastic increased over the last decade, and the annual growth rate of publication trends was 11.84%. The study revealed that 1131 authors wrote the 290 analysed documents, with a collaboration index of 4.04. Cooper DG (n = 11) was the most relevant author, McGill University (n = 21) was the most active university, and the Journal of Polymers and the Environment (n = 19) the leading journal. The outcome of this study can guide prospective research and offer vital information for improving the management of plastic waste.

“…In principle, the DN-PN/A process can remove 100% of ammonia nitrogen, but it is difficult to create a balance between the growth of heterotrophic microorganisms and autotrophic microorganisms (AOB, AnAOB, and other microorganisms) in one integrated reactor ( Ma et al, 2020 ). Thus, research needs to be conducted to develop or engineer optimized DN-PN/A microbiota ( Jiang et al, 2021 ).…”

“…Besides, the functional genes and pathways discovered in the microorganisms that can remove nitrogen pollutants can be expressed in the model organisms, such as Escherichia coli ( Wang et al, 2021a ), Clostridium perfringens ( Wang et al, 2011 ), Klebsiella pneumoniae ( Wang et al, 2021b ), and others ( Wang et al, 2020c ), to build genetically engineered strains for nitrogen pollutant removal ( Figure 1E ). These isolated strains, engineered strains, and enriched microbiota can be used for the construction of a series of synthetic microbiota with nitrogen removal ability, as well as those that can accomplish different nitrogen removal processes ( Jiang et al, 2021 ; Li et al, 2021c ). Based on the nitrogen pollutant types and concentration, proper synthetic microbiota can be selected and developed for nitrogen pollutant removal ( Figure 1E ).…”

The discharge of excess nitrogenous pollutants in rivers or other water bodies often leads to serious ecological problems and results in the collapse of aquatic ecosystems. Nitrogenous pollutants are often derived from the inefficient treatment of industrial wastewater. The biological treatment of industrial wastewater for the removal of nitrogen pollution is a green and efficient strategy. In the initial stage of the nitrogen removal process, the nitrogenous pollutants are converted to ammonia. Traditionally, nitrification and denitrification processes have been used for nitrogen removal in industrial wastewater; while currently, more efficient processes, such as simultaneous nitrification-denitrification, partial nitrification-anammox, and partial denitrification-anammox processes, are used. The microorganisms participating in nitrogen pollutant removal processes are diverse, but information about them is limited. In this review, we summarize the microbiota participating in nitrogen removal processes, their pathways, and associated functional genes. We have also discussed the design of efficient industrial wastewater treatment processes for the removal of nitrogenous pollutants and the application of microbiome engineering technology and synthetic biology strategies in the modulation of the nitrogen removal process. This review thus provides insights that would help in improving the efficiency of nitrogen pollutant removal from industrial wastewater.

“…Therefore, this strategy is very promising for the bioremediation of natural ecosystems without significant side effects. Despite increasing publications and involving multidisciplinary collaborations, microplastic degradation biotechnology still requires a lot of research and various strategies due to limitations on highly stable plastic properties, environmental conditions, the ability of microorganisms themselves, and the influence of microplastic-microorganism interactions (Shen et al, 2019;Jiang et al, 2021;Zhang et al, 2021). Biotechnology starts from obtaining microorganisms, and research that isolates microplastic-degrading microbes is still limited; therefore, tough isolates of microorganisms still need to be explored to achieve great success and sustainability.…”

Microplastics are contaminants in the form of tiny plastic fragments diluted in terrestrial and aquatic environments. Recently, these contaminants have become a concern due to their negative impact on the quality of life of living things. The isolation and examination of microplastic degrading microorganisms' ability from two large mature landfills were conducted. Therefore, this study aims to obtain bacteria and fungi as bioremediation agents that can degrade microplastics. The isolation process was conducted by direct and indirect (enriched) methods. Nutrient agar and potato dextrose agar media were used either in the form of a full or a tenth of a recipe with the addition of polyethylene, polypropylene, and polystyrene microplastics. Furthermore, indirect isolation used mineral media treated with the same microplastics. Colony morphology was observed to be the difference among isolates. The isolates were selected based on their ability to produce lipase in butter agar, and their ability to use microplastic as the only carbon source was examined. A total of 211 isolates were obtained, consisting of 74 bacteria and 137 fungi. One-third of the total isolates produced lipase. A bacterial isolate with the highest lipase index identified based on the 16S rRNA gene showed that it was Bacillus paramycoides. The isolate used all three types of microplastics, with the highest ability in polystyrene, which was degraded up to 11.12% in 42 days. In conclusion, microorganisms isolated from the landfill leachate have potential as bioremediation agents that degrade microplastics.
