Summary: Anaerobic biodegradation of toxic compounds in industrial wastewater is an attractive solution for energy and resource recovery, but faces challenges due to low kinetics compared to aerobic processes. Research on anaerobic phenol degradation focuses on microbiological and technological aspects to enhance competitiveness, with a gap still existing between aerobic and anaerobic performance. Efforts are needed to develop powerful technologies and effective strategies to improve the anaerobic process and move towards more sustainable wastewater treatment.

Summary: The bacterial strain Arthrobacter sp. C2 was isolated for atrazine degradation, showing degradation rates of 0.34, 1.94, and 18.64 mg/L/d at different concentrations. The optimal conditions for degradation were at 30°C and pH 7.0-9.0, and a metabolic pathway for atrazine degradation was proposed. The introduction of strain C2 into soil can enhance atrazine degradation and eliminate its toxic effects on wheat growth.

Summary: A strain with high phenol degradation capacity, named LA1, was isolated from the activated sludge of an urban wastewater treatment system in Panshan County, Liaoning Province. After identification and examination of environmental factors, it was determined that strain LA1, belonging to Stenotrophomonas sp., had optimal degradation conditions at pH 7, a growth temperature of 35 degrees C, and shaking at 150 r/min. Under these conditions, strain LA1 could completely degrade 1000 mg/L phenol in 18 h. It is the most powerful strain with phenol-reducing ability among the reported genera, providing theoretical and technical support for the treatment of phenol-containing wastewater and the sustainable development of the wastewater treatment industry.

Summary: A novel bacterium, Arthrobacter globiformis DC-1, capable of degrading DDT as its sole carbon and energy source, was isolated from DDT-contaminated agricultural soil. The bacterium can efficiently grow and degrade DDT at a wide range of concentrations, with the optimal degradation rate observed at 10 mg/LDDT with peptone as the carbon source at pH 7.5 and 30°C. This strain can also simultaneously degrade DDE, DDD, and DDT, with degradation rates reaching over 60% in 10 days. The biodegradation pathway of DDT by A. globiformis DC-1 involves dechlorination, dehydrochlorination, and mineralization to carbon dioxide.

Summary: This study isolated a novel halotolerant phenol-degrading yeast strain, SDP-1, from a coastal soil in Jiangsu, China, and identified it as Candida tropicalis based on morphology and genetic sequence analysis. SDP-1 efficiently removes phenol under a wide range of conditions, utilizes various phenol derivatives as carbon sources, and shows high tolerance to salts. Immobilized SDP-1 exhibits enhanced phenol degradation efficiency compared to free cells, making it a potential candidate for phenol-contaminated wastewater and soil treatment in hypersaline environments.

Summary: This study explores the degradation behavior of disposable face masks in simulated seawater through accelerated aging experiments. The release rates of microplastics (MPs) and dissolved organic carbon (DOC) from the masks are influenced by temperature and time. The time-temperature superposition principle is used to estimate the degradation time and predict the release of MPs and DOC into the ocean in the future.

Summary: Plastics and microplastics are widely present and accumulating in the environment, leading to increasing public attention. In addition to packaging plastics, materials from industries such as electronics, space and aviation are also accumulating, but receiving less attention. The production of degradable and biodegradable plastics is seen as a way to reduce environmental impacts, but enhancing the non-degradability of functional polymers is also a feasible option. Microbial colonization and deterioration pose significant challenges to these materials.

Summary: This study evaluated the keratinolytic activity of 37 strains of Trichophyton ajelloi and found that pigmented strains isolated from loamy soil were more efficient in degrading native feather keratin, while non-pigmented strains isolated from chernozem showed better abilities. The keratinolytic activity increased over time, as evidenced by the increase in extracellular keratinase activity and release of soluble proteins and peptides. Protease activity peaked in the first 7 days and again on day 28 of culture. The release of ammonium and sulfate ions, associated with an increase in pH, reached its maximum on day 21. Three pigment-producing strains were among the most active in releasing large amounts of ammonium and sulfate ions. The biodegradation of feather waste by Trichophyton ajelloi strains can be used to produce fertilizers suitable for plants with high sulfur requirements.
