Summary: In this study, a superheated steam (SHS) system was used to inactivate Bacillus cereus endospores on black pepper. Continuous and pulsed treatments were compared for their sporicidal effects and analyzed for their inactivation mechanisms. Pulsed SHS treatment at higher temperatures and shorter duty ratios showed higher microbicidal effects. The inactivation mechanisms were determined by measuring inner membrane damage, intracellular enzyme activities, and DNA integrity. Pulsed treatment accelerated enzyme inactivation prior to inner membrane damage, while both pulsed and continuous treatments resulted in reduced DNA integrity. These findings provide insights for the sterilization of black pepper in the food industry using SHS treatment.

Summary: The presence of Bacillus cereus in the rhizosphere of pak choi helps suppress clubroot and improve plant biomass. Inoculation with B. cereus reduces the severity of clubroot and enhances plant resistance and growth. Co-inoculation with both P. brassicae and B. cereus significantly reduces gall formation, offering potential for biological control of clubroot in cruciferous vegetables.

Summary: Extrusion as a densification process had a significant negative effect on all responses in SC-CO2 extracted red pepper oleoresin. Regardless of substrate pretreatment, the extraction yield and carotenoid yield were maximized at extreme conditions of 60 degrees C and 50 MPa. The extractable colour and antioxidant activity showed positive correlation, while oxidative index showed negative correlation with carotenoid content of SC-CO2 extracts.

Summary: This study utilized 16S rDNA high-throughput sequencing to investigate the effect of different doses of black soldier fly oil on the gut microbiota of pigeons. The results showed that the different doses of black soldier fly oil did not affect the microbial diversity of the pigeon's gut. However, increasing the concentration of black soldier fly oil significantly increased the abundance of beneficial bacteria, improving the composition and structure of the gut microbiota.

Summary: Solid-state fermentation can improve the nutritional quality of plant-based feed, but the relationship between microbes and metabolites in fermented feed is still unknown. In this study, corn-soybean-wheat bran meal feed was inoculated with Bacillus licheniformis, Bacillus subtilis, and lactic acid bacteria, and the changes in microflora and metabolites during fermentation were investigated. The results showed that protein levels increased while glycinin and beta-conglycinin levels decreased in the fermented feed. Pediococcus, Enterococcus, and Lactobacillus were the predominant microbes in the fermented feed, and arginine and proline metabolism were the most important pathways.

Summary: This study investigated the effects of five cooking methods on the quality, sensory, and flavor compounds of Sichuan pepper oleoresin (SPO) to understand its overall flavor and changes during practical application. The SPO after different cooking methods were distinguishable by electronic nose and principal component analysis. Thirteen compounds were found to explain the differences in volatile compounds through OPLS-DA analysis. It was observed that pungent substances were significantly reduced and bitterness increased after cooking.

Summary: The endophytic Pseudomonas putida BP25 associated with black pepper exhibited volatile-mediated antagonism against the rice blast fungus Magnaporthe oryzae 1637. The major chemical components identified in the volatiles were 2-methylpyrazine and 2-ethyl-3,6-dimethylpyrazine, both of which inhibited the developmental stages of the fungus. In planta experiments on rice seeds and seedlings demonstrated that these compounds reduced blast disease incidence and induced the expression of defense genes in the plants.

Summary: Fluorescence microscopy and qPCR-based pathogen tracking tools were developed to study the growth and development of Puccinia graminis f. sp. tritici on nonhost plant leaves. Identification of stem rust race-Puccinia graminis f. sp. tritici 40A was achieved using gene sequences, and a qPCR assay with high sensitivity was developed for quantitation of stem rust fungus. The study showed that both nonhost (rice) and host (wheat) plants supported similar growth stages of the fungus, but nonhost plants did not exhibit rusting symptoms.

Summary: In this study, the leaf endophytic microbiomes of different rice genotypes in mountain and plateau zones of India were analyzed using metagenomic NGS and conventional microbiological methods. The results showed that geographical location had a significant impact on the composition of the endophytic microbiome, with Proteobacteria, Bacteroidetes, Firmicutes, and Actinobacteria being the most abundant bacterial phyla. The core microbiome analysis revealed associations of various bacterial genera with the leaf endosphere, and SparCC network analysis demonstrated complex interactions among microbial communities. This research provides valuable insights for microbiome-assisted crop management and potential microbiome reengineering strategies in the future.
