Summary: Fungi-induced postharvest diseases are a major cause of food loss and waste. Antagonistic yeasts provide a biological method to control decay caused by fungi and detoxify mycotoxins sustainably. This review summarizes studies on preventing phytopathogenic and mycotoxigenic fungi in fruits and their biocontrolling and biodetoxification mechanisms.

Summary: This study evaluated the effects and mechanism of nanosponges (NSs) in addressing the injuries caused by recombinant V. vulnificus hemolysin (rVvhA). NSs were found to reverse rVvhA-induced apoptosis and necrosis, improve toxin-induced intracellular ROS production, ATP depletion, and apoptosis signaling pathway disruption. In mouse models, NSs attenuated rVvhA-induced acute toxicity, septicemia-associated inflammation, and tissue damage.

Summary: This study investigates the effect of nanodiamonds on the key parameters of modelled bioremediation of river sediments polluted with phenol, as well as their impact on the structures and functions of microbial communities. The results show the positive role of nanodiamonds in the presence of high concentrations of phenol, leading to the evolution of xenobiotic biodegradation potential through an increase in non-culturable bacteria.

Summary: Mercury-resistant bacterial isolates were obtained from industrial wastewater in Pakistan, and one of these isolates, Bacillus cereus AA-18, showed promising resistance against mercury due to the presence of the merA gene encoding mercuric reductase. Scanning electron microscopy analysis revealed the accumulation of mercury on the cell surface of immobilized B. cereus AA-18. Furthermore, the inoculation of immobilized B. cereus AA-18 successfully remediated 86% of mercury in industrial wastewater within 72 hours.

Summary: This article investigates the sources and prevention measures of aflatoxin contamination, a carcinogenic substance produced by fungi species in the soil. Through investigating soil properties and soil microbial distribution, the sources of aflatoxin are identified, and appropriate prevention and control measures are developed, such as the development of biofungicide ARC-BBBE and nanomaterials for detoxification. These findings provide an effective and feasible approach for preventing and controlling aflatoxin contamination.

Summary: In recent years, there has been a growing concern about milk pollution by aflatoxin M1 due to the increasing prevalence of aflatoxins in animal feeding and dairy product consumption. A study was conducted to determine the transfer of aflatoxin B1 into milk and its effects on production and serological parameters in goats. Goats were exposed to different doses of aflatoxin B1 for 31 days and the concentration of aflatoxin M1 in milk was found to significantly increase with the amount of aflatoxin B1 ingested. However, the ingested amount did not affect the aflatoxin M1 carryover, indicating a certain resistance of goats to the effects of aflatoxin B1.

Summary: The dilute acid hydrolysis of lignocellulose biomass can be used for production of cellulosic ethanol, but it faces technical barriers due to acid-catalyzed dehydration reactions. This study introduces a novel biodetoxification method to overcome these barriers and successfully produces ethanol from corn stover through dilute acid hydrolysis.

Summary: In recent years, there has been an increase in the occurrence of fowl adenovirus 2 (FAdV-2) in China, posing a significant threat to the poultry industry. This study investigated the epidemiology, phylogenetic relationship, genomic characteristics, and pathogenicity of FAdV-2. The results showed that FAdV-2 was the most commonly detected serotype among various FAdV serotypes. Genetic analysis revealed that these FAdV-2 strains formed a distinct branch within the FAdV-D group and had a high nucleotide similarity with reference strains. Recombination analysis identified recombination events between FAdV-2 and FAdV-11 in some strains. Pathogenicity experiments demonstrated that a recombinant FAdV-2 strain caused a high mortality rate and more severe disease in chickens. These findings contribute to our understanding of FAdV-2 and provide a basis for vaccine development.

Summary: This study evaluated the effects of CP and ME on the performance and nutritional value of Japanese quail lay chicken. The results showed that protein and energy levels significantly influenced all productive outcomes except feed conversion ratio. The combination of dietary energy and protein levels had a substantial effect on all egg quality trials evaluated. It is recommended to feed layer Japanese quail between the ages of 8 and 20 weeks during the summer with a dietary energy content of 2,900 kcal ME/kg and 20% CP.

Summary: The study investigates the functional variants associated with chicken eggshell color in the SLCO1B3 gene by measuring the eggshell color of Lueyang black-boned chickens and analyzing the genetic data. It identifies 15 variants in SLCO1B3 that are significantly associated with eggshell color. However, the functional analysis shows that one specific variant, 1B3_SNP108, does not have a significant effect on promoter activity. This study highlights the importance of SLCO1B3 and its variants in breeding eggshell color.

Summary: This study investigated the welfare and health of laying hens in a multitier system. The results showed that the spatial distribution of hens changed with increasing age, and lower-ranking hens preferred to stay in lower tiers to avoid competition but still had access to resources. This improved the welfare and health of the hens near the end of the laying cycle.

Summary: This study examined the effect of risk perceptions on preventive behavior among vendors in the live poultry wholesale market and the live poultry retail market in Guangdong Province using the health belief model and structural equation modeling. The results showed that perceived severity and perceived benefits positively influenced vendors' self-efficacy in the wholesale market, while perceived barriers negatively affected self-efficacy in both the wholesale and retail markets. Moreover, cues to action mediated the relationship between perceived severity, perceived benefits, and self-efficacy, and also mediated the effect of perceived susceptibility among wholesale market vendors.
