Summary: Traditional grain vinegar is fermented using multiple acetic acid bacteria (AAB) at various temperatures. Multiple AAB showed higher acid production ability and increased titratable acidity compared to single AAB. Mixing two AAB types and fermenting at low temperatures (20 degrees C) increased volatile flavor compounds in traditional grain vinegar.

Summary: The familiarity and awareness of growers regarding the southern red mite (SRM) was evaluated in 2020, showing confidence in identifying the pest but uncertainty in recognizing the damage caused by their feeding. Limited miticide options were reported, indicating the need for more tools and educational material to address this issue. Among the tested miticides, fenpyroximate and fenazaquin performed the best at suppressing SRM, followed by acequinocyl, bifenazate (high rate), and spiromesifen. Sulfur-based miticides were ineffective. Assessing the efficacy of miticides against SRM allows growers to diversify their pest control strategies and protect their blueberry plantings.

Summary: Research showed that the use of BC-NT-TT coating significantly prolonged the storage life of blueberries and improved several quality parameters, while reducing the number of microorganisms. In contrast, BC-NT coatings increased certain nutritional components in blueberries, while BC coatings enhanced the titratable acidity value.

Summary: Blueberry aroma is a key factor influencing consumer purchasing decisions, and this study optimized a SPME-GC/MS method for quantifying volatile compounds in blueberries. The method was validated for sensitivity, reproducibility, linearity, and accuracy, and revealed terpenes, aldehydes, and alcohols as the most abundant volatile fractions in different blueberry cultivars. Key compounds like linalool and 2-(E)-hexenal differentiated blueberry cultivars, with enantiomeric analyses showing an excess of (-)-limonene, (-)-alpha-pinene, and (+)-linalool in all cultivars.

Summary: Although blueberries have been extensively studied, little information exists on their flavonol glycosides composition and content. In this study, 44 flavonols and chlorogenic acid were identified in 30 samples of Highbush and Rabbiteye blueberry, with some compounds being found in blueberries for the first time. Different phenolic compound profiles allow the distinction of blueberry groups according to Principal Component Analysis.

Summary: This study in Oregon, USA, showed that European foulbrood was prevalent in honey bee colonies pollinating blueberries, and there was a correlation between the population size of adult workers in the colonies and blueberry yield. The research found that while average colony strength did not predict fruit set variation, it was related to yield variation, suggesting that promoting stronger colonies could increase blueberry yield without the need to increase hive density.

Summary: This study reported the isolation and characterization of 304 Campylobacter specific bacteriophage isolates from broiler and swine sources. The most promising 59 campylophage candidates were selected based on their lytic activity, and RAPD-PCR technique was found to be effective only for Group II campylophages. Bacteriophage isolates within the same genotype displayed different host ranges, leading to the differentiation of 13 campylophages from Group II and 8 from Group III.

Summary: This study compares the composition of microbiota in the intestines of wild and aquaculture red cusk-eel and finds significant differences between the two. The microbiota in aquaculture conditions is dominated by Firmicutes, while in the wild conditions it is dominated by Tenericutes. Differences in predicted metabolic pathways were also observed, with a focus on lipid metabolism in the wild conditions.

Summary: The study analyzed the survival and host-pathogen interactions during infection by C. glabrata, C. nivariensis and C. bracarensis in G. melonella. Results showed that C. glabrata was the most virulent species, while C. bracarensis was the least virulent. G. melonella had stronger immune responses to C. bracarensis compared to the other two species.

Summary: Mycoses are responsible for millions of infections worldwide each year, with invasive candidiasis being the most common and having high morbidity and mortality. The incidence of other Candida species, such as Candida parapsilosis, Candida glabrata, and Candida auris, is increasing. These pathogens often show reduced susceptibility to commonly used antifungal drugs, and the emergence of multi-drug-resistant strains continues to rise. Therefore, the search for new molecules that target these pathogens in a different way is urgent. Antimicrobial peptides, found in nature, have advantages over traditional antifungal agents and are considered a promising option for treating a wide range of microbial infections.

Summary: In addition to human medicine, antimicrobials are used in food animals and aquaculture for therapeutic purposes against bacterial infections. However, their use in aquaculture can lead to environmental consequences and the spread of bacterial resistance genes. Probiotics and bacteriocins derived from lactic acid bacteria offer potential alternatives to antibiotics for controlling bacterial infections.

Summary: This study investigated the diversity, composition and functional prediction of intestinal microbiota in reared Seriolella violacea. The dominant phyla were Firmicutes, Proteobacteria, Fusobacteria, and Tenericutes. The most abundant genus, Candidatus Arthromitus, had been associated with immune response maturation and protection against bacterial infections. Analysis also revealed high levels of genes for sugar metabolism in the intestinal microbiota of S. violacea.

Summary: Atlantic salmon fed a carbohydrate-rich diet showed suboptimal growth performance and metabolic disturbances. The study aimed to investigate the effects of graded levels of digestible carbohydrates on the distal intestine digesta microbiota in Atlantic salmon. The results demonstrated that feeding a high digestible carbohydrate diet led to negative effects on growth parameters and liver health, including increased lipid vacuolization and expression of fatty acid synthase. The composition of distal intestine digesta microbiota also changed with the carbohydrate-rich diet. Furthermore, certain lactic acid bacteria were found to be negatively correlated with hepatic steatosis and other liver health indicators. The potential use of lactic acid bacteria as probiotics to improve liver health in carnivorous fish fed a fatty liver-induced diet deserves further investigation.

Summary: This study evaluated the pathogenicity of Candida auris using isolates from different clinical origins in two alternative host models, Caenorhabditis elegans and Galleria mellonella. The study found that the aggregating phenotype isolate was less virulent but had higher biofilm-forming capacity compared to non-aggregating isolates. Blood isolates were more virulent in the G. mellonella model, indicating potential heterogeneity in virulence influenced by aggregation phenotype and clinical origin.
