Summary The comprehensive utilisation of food waste has become a global development demand for enhancing their added value. This study aimed to develop and utilise physiological fruit drop Citrus aurantium L. var Daidai with rich phenolic acids flavonoids. Therefore, different concentrations (1%, 3%, 5%, 10% wt, based on pullulan weight) daidai extracts (DE) were incorporated into pullulan/bacterial cellulose (BC) packaging film (PB2‐DE). effects DE composite films comprehensively evaluated. It was found that the mechanical properties, ultraviolet barrier antioxidant properties improved addition DE. Moreover, application tests have verified containing can effectively maintain attractive quality strawberries. Conclusively, results demonstrated feasibility incorporation increase value potential applicability in strawberry preservation.

Tracking the Evolution of Microbial Communities on Microplastics through a Wastewater Treatment Process: Insight into the “Plastisphere”

Water, Год журнала: 2023, Номер 15(21), С. 3746 - 3746

Опубликована: Окт. 26, 2023

Microplastics (MPs), which result from the breakdown of plastic waste, have become ubiquitous in various environmental compartments. The “plastisphere”, referring to unique bacterial communities inhabiting debris, includes pathogens and antibiotic resistance genes. Wastewater treatment plants (WWTPs) are hotspots for plastisphere formation, but significant releases MPs still occur. This study investigates microbial on polystyrene (PS) through situ deployment across primary, secondary, tertiary WWTP stages. Biofilms formed PS exhibited greater diversity than background waters. Certain genera acted as pioneers biofilms, attracting facilitating accumulation other microbes biofilms became more resistant processes compared freely floating bacteria. sheds light evolution within WWTPs their roles carriers effluents, with implications public health. Understanding these dynamics is crucial effective control over pollution WWTPs.

Microplastic contamination in terrestrial environments has risen significantly, far exceeding levels marine environments. This shift underscores the concerning prevalence of microplastics (MPs) sewage sludge and soil, raising environmental apprehensions. Microplastics from various sources accumulate systems, consequently, soil have transformed into primary reservoirs microplastic pollutants, capable infiltrating aquatic ecosystems. While using to enrich provides nutrients, it simultaneously introduces substantial content, posing hazards. These can altering its properties potentially polluting deeper layers groundwater, compounding risks. review scrutinizes abundance, types, shapes evaluating their impacts suggesting future research directions. Statistical analysis reveals higher concentrations (271 Particles/kg dry weight) than (34.6 Particles/kg). Strong correlations between (R2 = 0.95) underscore significant influence application on The p-value 0.0001 indicates a correlation MP amounts sludge, while 0.47 suggests no association wastewater sludge. Research confirms that properties, microbial communities, characteristics, contingent attributes conditions. Predominantly, found are fibers fragments, often linked agricultural fertilizer use. detrimentally affect bulk density aggregate stability, impairing structure surface. Furthermore, presence alters pollutant transport behavior emphasizing imperative investigate microplastics’ effects mechanisms for mitigating health
