Pleurotus geesteranus, being rich in nutrients and moisture, easily loses water and wilts after harvest, reducing its commercial value. Furthermore, film packaging leads to excessive humidity in the internal environment, causing products to decay. In this study, polylactic acid (PLA) and chitosan (CS) were used as film-forming substrates to prepare a one-way moisture barrier bilayer film containing 0.25% cinnamaldehyde nano-emulsion (CANE). The microstructure, physical properties, optical properties, mechanical properties, moisture barrier properties and sustained release behavior of the film were investigated and its application in the preservation of P. geesteranus was evaluated. The results showed that the combination between PLA and CS could effectively make up for the defects of the monomer film, and the layers in the composite film with 0.25% CANE were tightly bound to each other, with a retention rate of 42% for cinnamaldehyde (CA). The film had strong ultraviolet resistance and the smallest settling speed of water droplets. The P layer had good water vapor barrier properties, and the C layer had good hydrophilicity. Compared with polyethylene (PE) film packaging, the 0.25% CANE-PLA-CS bilayer film significantly inhibited the browning and respiratory intensity of P. geesteranus during postharvest storage, delayed the increase in mass loss, soluble solids content, browning degree, electrical conductivity and malondialdehyde (MDA) content, reduced the activities of polyphenol oxidase (PPO) and peroxidase (POD) and maintained higher superoxide dismutase (SOD) activity. These results indicated that the one-way moisture barrier bilayer film could effectively delay the browning and aging of P. geesteranus and maintain its commercial value. This study provides theoretical support for the preparation of novel packaging materials for mushrooms and is of guiding significance to the reduction of post-harvest loss of P. geesteranus.

Studies have shown that Geotrichum citri-aurantii can adjust the pH of infection sites to enhance its pathogenicity, and PacC, a key transcription factor in the pH signal transduction pathway, plays an important role in fungal response to environmental pH changes, but the role of PacC in G. citri-aurantii remains unclear. In this study, two candidate PacC genes were annotated from the genome of G. citri-aurantii and analyzed by bioinformatics methods and their expression patterns under different pH conditions were also studied. The results showed that PacC1 and PacC2 belonged to the C2H2 protein family, and were closely related to the PacC of Penicillium digitatum. PacC1 and PacC2 had differences in chromosomal location, protein molecular mass and isoelectric point. Under in vitro conditions, G. citri-aurantii could adapt to a wide range of pH, and the optimal pH value was found to be 3.0. The expression of PacC1 and PacC2 was regulated by pH, and their expression trends were similar. Under in vivo conditions, the pH of sour rot lesions in ‘Miyagawa-wase’ mandarin fruit tissue at pH > 3.0 decreased significantly with the progression of the disease, while the pH of sour rot lesions in Eureka lemon fruit tissue at pH < 3.0 increased significantly, and the relative expression levels of PacC1 and PacC2 showed an increasing trend. In conclusion, it can be seen that the environmental pH affects the growth of G. citri-aurantii, which in turn regulates the environmental pH. Due to the differences in gene structure and physicochemical properties, the degree and mode of pH response are different between the two PacC genes. They play an important role in the wide pH adaptability of G. citri-aurantii and in accelerating its infection process in citrus fruit.

Metal organic frameworks(MOFs) is a new type of crystalline porous material, which has the characteristics of high surface area, high porosity and low synthesis cost. MOFs have been widely used in the field of catalysis due to its unique porous structure and discrete active centers. Firstly, the types and synthesis methods of common MOFs are introduced, and the characteristics of different synthesis methods are summarized. Then, the latest research progress of MOFs as photocatalysts for the efficient removal of heavy metals, dyes, and antibiotics in wastewater is reviewed. The photocatalysis of MOFs and composite materials on different pollutants, reaction efficiency, and various experimental conditions are performed. Finally, the prospects and challenges of MOFs as photocatalysis in wastewater treatment are discussed.

The translation of The Analects by Roger T. Ames and Henry Rosemont was meant to contest the cultural universalism propagated by Western scholars with their pride in Western philosophy and religion. The text is characterised by post-structuralist features—the co-existence of transliteration and interpretation, creative writing and imitation, subversion and fluency. Some prominent elements of The Analects of Confucius: A Philosophical Translation are discussed at length in this article: the emphasis on process rather than result, the focus on social interaction rather than on isolated individuals. The translation is also noted for the translators' creative interpretation, their use of quotations from various sources and their artistic language. The article analyses the translators' strategies embodied therein and generalise about the project's relevance to translation studies. [ABSTRACT FROM AUTHOR]
