Abstract ：
The antifungal mechanism of Bacillus velezensis (B. velezensis) against Phyllosticta capitalensis (P. capitalensis), a pathogen isolated from guava fruits and its efficacy in controlling guava black spot disease were systematically investigated. The minimum inhibitory concentration (MIC) of B. velezensis against P. capitalensis was identified to be 10(4) CFU/mL. Microscopic observations revealed significant morphological alterations in P. capitalensis mycelium following B. velezensis treatment, suggesting compromised cell membrane integrity and a consequent increase in membrane permeability. Moreover, B. velezensis treatment induced elevated levels of malondialdehyde (MDA), hydrogen peroxide (H2O2) and superoxide anions (O-2 center dot(-)), accompanied by reduced catalase (CAT) and peroxidase (POD) activities in P. capitalensis, thereby effectively inhibiting its growth. Transcriptome analysis provided further evidence that B. velezensis might exert its antifungal effects through destabilizing the cell membrane and attenuating the antioxidant defense capacity of P. capitalensis. B. velezensis treatment significantly slowed the disease development caused by P. capitalensis in guavas, with diameters measuring only 0.097 cm at 4 days and 0.423 cm at 8 days, which substantially lower than those of the CK group (P < 0.01). These findings indicate that B. velezensis holds considerable potential as an effective biocontrol agent for managing guava black spot disease.

Abstract ：
Phyllosticta capitalensis (P. capitalensis) is a major postharvest pathogen of guava, causing black spot disease, which results in serious rot and significant economic losses. This study demonstrated that the sterile fermentation supernatant of Bacillus velezensis (BT313-SFS) effectively inhibited P. capitalensis, with a minimum inhibitory concentration (MIC) of 300 mL/L. BT313-SFS maintained stable antifungal activity across a pH range of 4-8 and temperatures between 25 and 60 degrees C. However, its antifungal efficacy was significantly reduced by treatment with trypsin and alkaline protease. Cellular-level analysis revealed that BT313-SFS altered the morphology of P. capitalensis, destroyed the cell wall and membrane, suppressed intracellular antioxidant enzyme activities, raised reactive oxygen species (ROS) levels, and induced oxidative cellular damage. Furthermore, BT313-SFS impaired mitochondrial function and disrupted the tricarboxylic acid (TCA) cycle, interfering with cellular energy metabolism and inhibiting P. capitalensis proliferation. Thus, BT313-SFS exhibited excellent preservation effects by reducing guava respiration, retarding color browning, and maintaining cell membrane integrity, thereby extending the storage life of the fruit. These results established BT313-SFS as a promising natural antifungal agent for controlling postharvest black spot disease in guava.

Abstract ：
Novel covalent organic frameworks (COFs) based PAN@TpBD(NH2)(2) electrospun composite nanofiber mem-branes (ECNMs) were fabricated as strong anion exchange sorbent by implementing electrospinning technology. The finished sorbent was characterized, and key parameters of pipette-tip solid phase extraction (PTSPE) pro-cedures were investigated. Inorganic arsenic (iAs) was successfully separated from rice under the optimal precondition conditions, and quantified by hydride generation-atomic fluorescence spectrometry (HG-AFS). This PTSPE-HG-AFS methodology achieved 0.015 mu g L-1 detection limit, 4.67 % relative standard deviation, and 86.48 similar to 99.11 % recoveries. In this work, preparation and characterization of this novel COFs-based anion exchange sorbent, PAN@TpBD(NH2)(2) ECNMs, is described and its suitability for PTSPE applications is demonstrated.

Abstract ：
This study focused on the development of a gaseous ClO2 treatment system that contained dry ice that was used to form carbon dioxide (CO2) and an absorbent pad with sodium chlorite (NaClO2) solution for ClO2 gas gen-eration. Furthermore, the effects of ClO2 gas on the populations of Listeria monocytogenes and the quality properties of table grapes during cold storage were evaluated. The system continuously released the sufficient concentrations of ClO2 gas to treat berries during 30 d of cold storage. After 20 h of ClO2 gas treatment, the populations of Listeria monocytogenes decreased from 5.88 log CFU/g to a non-detectable (ND) level. There were no significant (p > 0.05) changes in the color parameters (L*, a*, and b*) of table grapes treated with ClO2 gas. The firmness, weight, total soluble solids (TSS), and titratable acid (TA) losses of table grapes were significantly (p < 0.05) reduced by ClO2 gas, while Vitamin C was unaffected. Additionally, the residual ClO2 of table grapes were <0.5 mg/kg, which is considered a safe level. Overall, the novel gaseous ClO2 treatment system may be used as an effective intervention technology to improve the safety and quality of table grapes during cold storage.

Abstract ：
Background and objectives Rice contains an order of magnitude higher inorganic arsenic (iAs), a class 1 non-threshold carcinogen, than other terrestrial crops. To reduce iAs in cooked rice, several methods have been proposed such as washing until clear, cooking with high water-to-rice ratio (W/R) then discarding excess water, or continuously percolating near-boiling water. The traditional method practiced by 1.6 billion East Asians, washing and cooking with low W/R until dry, removes only a small percentage of iAs. A new approach was investigated to reduce iAs in cooked rice. Findings Brief (10 min) soaking (W/R 10) at above gelatinization temperature (80 degrees C) reduced iAs in rice by up to 48.4%. A soaking protocol was developed for public use that on average reduced 39.5 +/- 6.6% (n = 12) iAs in non-waxy white rice. Conclusions Brief above-gelatinization-temperature soaking effectively reduces iAs in cooked white rice. Significance and novelty Above-gelatinization-temperature soaking was applied for the first time to cut iAs in cooked rice; thereby chronic iAs exposure and cancer risk can be reduced for rice consumers.
