“…The P. aeruginosa used in this study was prepared and enriched by isolating the gut extract from PS-ingested superworms, followed by culturing in PS-added liquid LCFBM media for 60 days [ 8 ]. Our current results as well as our previous studies have shown that a single bacteria strain can depolymerize several different types of plastics, although with different efficiencies [ 19 ] ( Figure 4 B). The P. aeruginosa -mediated PE biodegradation efficiency in this current work was much faster than for any of the other plastic types tested (PS, PPS or PP) ( Figure 4 B).…”

“…Bacteria have to utilize plastic to produce energy for their survival and amplification when it is the sole available carbon source. Thus, the biodegradation efficiencies of different types of plastics could affect the growth rates of P. aeruginosa and change their population characteristics [ 19 ]. To compare the effects of different plastic types on the growth of P. aeruginosa , we measured changes in the bacteria number in a liquid LCFBM media supplied with different plastic.…”

“…Styrofoam PS (99.5% purity, Myung-IL FOAMTEC, Daegu, South Korea) was supplied as the sole carbon food source to enrich the PS-degrading bacteria in guts of these superworms. The isolation of gut bacteria from fourth instar larvae of superworms was following our previous protocols [ 8 , 19 ]. The gut was extracted from larvae anesthetized by immersing in 70% ethanol and then washed with saline water (SW).…”

“…can depolymerize several plastic types, including polyvinyl chloride, polyurethane, polyvinyl alcohol, PE and PS [ 18 ]. P. aeruginosa , isolated from the gut of superworms, was shown to be able to degrade PE, PS and polyphenylene sulfide (PPS) in an earlier work from our group [ 8 , 19 ]. We have further identified and verified that serine hydrolase (SH), a candidate enzyme, participates in the plastic biodegradation process, via RT-qPCR analyses and enzyme inhibitor treatment assays [ 8 ].…”

“…Besides Pseudomonas sp., several other gut bacteria in worms have also been reported to participate in the biodegradation process of ingested plastics [ 15 , 16 , 17 ]. Although, single bacterial species can degrade several plastic types, the biodegradation efficiencies toward each different type of plastic vary enormously [ 18 , 19 ]. Herein, we have compared the biodegradation efficiencies of a P. aeruginosa strain toward four different types of plastic: PE, PS, PPS and polypropylene (PP).…”

Plastic waste worldwide is becoming a serious pollution problem for the planet. Various physical and chemical methods have been tested in attempts to remove plastic dumps. However, these have usually resulted in secondary pollution issues. Recently, the biodegradation of plastic by fungal and bacterial strains has been spotlighted as a promising solution to remove plastic wastes without generating secondary pollution. We have previously reported that a Pseudomonas aeruginosa strain isolated from the gut of a superworm is capable of biodegrading polystyrene (PS) and polyphenylene sulfide (PPS). Herein, we demonstrate the extraordinary biodegradative power of P. aeruginosa in efficiently depolymerizing four different types of plastics: PS, PPS, polyethylene (PE) and polypropylene (PP). We further compared biodegradation rates for these four plastic types and found that PE was biodegraded fastest, whereas the biodegradation of PP was the slowest. Moreover, the growth rates of P. aeruginosa were not always proportional to biodegradation rates, suggesting that the rate of bacterial growth could be influenced by the composition and properties of intermediate molecules produced during plastic biodegradation, and these may supply useful cellular precursors and energy. In conclusion, an initial screening system to select the most suitable bacterial strain to biodegrade certain types of plastic is particularly important and may be necessary to solve plastic waste problems both presently and in the future.

Implantable medical devices (IMDs) are designed to sense specific parameters or stimulate organs and have been actively used for treatment and diagnosis of various diseases. IMDs are used for long‐term disease screening or treatments and cannot be considered for short‐term applications since patients need to go through a surgery for retrieval of the IMD. Advances in bioresorbable materials has led to the development of transient IMDs that can be resorbed by bodily fluids and disappear after a certain period. These devices are designed to be implanted in the adjacent of the targeted tissue for predetermined times with the aim of measurement of pressure, strain, or temperature, while the bioelectronic devices stimulate certain tissues. They enable opportunities for monitoring and treatment of acute diseases. To realize such transient and miniaturized devices, researchers utilize a variety of materials, novel fabrication methods, and device design strategies. This review discusses potential bioresorbable materials for each component in an IMD followed by programmable degradation and safety standards. Then, common fabrication methods for bioresorbable materials are introduced, along with challenges. The final section provides representative examples of bioresorbable IMDs for various applications with an emphasis on materials, device functionality, and fabrication methods.

Microplastics (MPs) are a class of emerging contaminants that have gained significant attention in recent years. The presence of MPs in the aquatic environment is reported to have serious potential environmental and health impacts. Therefore, it is essential to develop efficient and sustainable strategies for the remediation of MPs from the aqueous environment. Traditional techniques for the remediation of MPs from an aqueous environment have limitations, including high costs and the production of secondary pollutants. In this scenario, bioremediation offers several advantages and has emerged as a cost‐effective, eco‐friendly, and efficient strategy for the removal of MPs from water. This article critically reviews the recent progress in the applications of bioremediation for the removal of different MPs from water. The effects of key factors such as the characteristics of MPs, environmental conditions, and types of microorganisms on the removal of MPs are elaborated in detail. The underlying mechanisms involved in the removal of MPs by microorganisms are also discussed comprehensively. Major technological challenges are identified, and recommendations for future research are provided. Despite several challenges, bioremediation is a promising approach that can revolutionize the MP removal process if the major challenges are addressed.
