Microbial degradation of polyethylene polymer: current paradigms, challenges, and future innovations.

Polyethylene (PE) is the second most commonly used plastic worldwide, mainly used to produce single-use items such as bags and bottles. Its significant resistance to natural biodegradation results in the accumulation of PE in landfills, leading to various ecological and toxicological consequences. Despite extensive research on the microbial degradation of PE, achieving complete biodegradation remains a challenge.

Diversity and dynamic response of anaerobic ammonia oxidation granular sludge.

Red anaerobic ammonia oxidation (Anammox) granular sludge (AnGS) has been reported in successfully operating Anammox systems, and its color is associated with sludge activity. However, in long-term operating systems, AnGS exhibits different sensory colors, physical structures, community structures, and denitrification performance, but the relationship between them has not yet been elucidated. The AnGS of the Anammox system, which has been in operation for more than a decade, can be divided into two main categories: red and white.

Harnessing Lignin Nanoparticles for Sustainable Enzyme Immobilization: Current Paradigms and Future Innovations.

Lignin, a vital plant component, is key in providing structural integrity and is the second most abundant biopolymer in nature. The growing interest in sustainable and efficient biocatalysis has driven the exploration of lignin nanoparticles (LNPs) as a promising platform for enzyme immobilization. Given lignin's abundance and structural role in plants, converting it into nanoparticles offers a potential eco-friendly alternative to traditional supports.

[Correlation between nasal mucosal microbiota diversity and the pathogenesis and prognosis of chronic sinusitis].

To analyze the correlation between nasal mucosal microbiota diversity and the pathogenesis and prognosis of chronic sinusitis. A total of 80 patients with chronic sinusitis（CRS） admitted to Second Affiliated Hospital of Suzhou University were selected as the research group, and 80 patients with chronic dacryocystitis and nasal septum deviation without sinus inflammation admitted to our hospital during the same period were selected as the control group, nasal secretory specimens were collected under nasal endoscopic guidance by nasal swab, and matrix-assisted laser desorption ionization classification time mass spectrometry, anaerobic bacterial culture and common bacterial culture were performed to compare the differences in nasal mucosal flora between groups. Patients with chronic sinusitis were followed up for 6 months, and nasal secretions were collected again to detect microflora, and the patients were divided into relapse group（21 cases） and non-recurrence group（59 cases） according to whether the patients had relapse.

Weak Coupling Strategy to Construct High-Performance Sm/Tb-Doped Lanthanide Coordination Polymer Luminescent Sensor for DO Detection.

Accurate measurement of the purity and content of heavy water is of great concern in nuclear energy, the chemical industry, and biomedicine. Since the physical and chemical properties of DO and HO are very similar, achieving luminescent detection is challenging. Due to the difference in the vibrational frequency of the O-D and the O-H bonds, the quenching efficiency of the excited state of Ln is different, which leads to a significant difference in the optical properties of Ln.
