Summary: The bioprotective extracts from Lactobacillus acidophilus were effective in completely inhibiting spoilage strains in refrigerated meat, while extracts from Latilactobacillus curvatus had a bacteriostatic effect when combined with L. acidophilus. The use of more accurate tools to prevent the growth of deteriorating species can contribute to extending the shelf-life of fresh meat without compromising quality.

Summary: Fourteen lactic acid bacteria (LAB) strains were isolated from the intestinal tract and feces of piglets, and only 12 strains were confirmed as Limosilactobacillus fermentum, Lactobacillus acidophilus, and Lactiplantibacillus plantarum. Two strains, L. acidophilus IBNA 76 and L. plantarum IBNA 84, showed high survival rates under low pH and bile salts conditions. They also exhibited resistance to multiple antibiotics. After encapsulation using the spray-drying technique, the probiotic viability decreased but still remained promising. These findings suggest that L. acidophilus IBNA 76 and L. plantarum IBNA 84 could be considered as probiotic candidates for piglet nutrition.

Summary: This study evaluated the probiotic potential of lactic acid bacteria from different dairy sources and screened probiotics with anti-allergic activity, analyzing their effects on cell signaling pathways and cytokines. Some strains showed potential anti-allergic properties and could be used for alleviating allergic diseases, as demonstrated by their downregulation of histamine and cytokines TNF-alpha and IL-4. Additionally, the probiotics significantly decreased the phosphorylation of Lyn and Syk in RBL-2H3 cells, suggesting their potential for treating allergic and inflammatory diseases.

Summary: Biotherapeutic strategies, such as using engineered microbes to deliver therapeutic molecules, have great potential. However, the lack of precise tools to detect these microbes and their products hinders our ability to monitor and adjust therapeutic delivery. In this study, a bioluminescent peptide tagging system was adapted for lactic acid bacteria, which are commonly used as delivery vehicles for therapeutics. This system allowed sensitive detection of recombinant therapeutic proteins and could be used in continuous-culture bioreactor systems. Furthermore, it enabled rapid detection of administered microbes in intestinal and fecal samples.

Summary: 3-PBA, a major degradation intermediate of pyrethroids, poses a severe threat to the ecosystem and human health due to its widespread existence in the environment. This study evaluated the adsorption capacity of L. plantarum RS20 towards 3-PBA and found that strain RS20 could be employed as a biological detoxification agent for humans and animals by eliminating 3-PBA from foods, feeds, and the digestive tract.

Summary: This study proposes a new flowchart to identify strains with probiotic potential for the management of IBS and IBD. In vitro testing of immunomodulatory properties, barrier-strengthening effect, and the production of SCFAs and AhR agonists are included in the flowchart. Principal component analysis is used to identify strains associated with an anti-inflammatory profile. The flowchart is validated through testing in mouse models, showing potential beneficial effects on colonic inflammation and hypersensitivity.

Summary: This study presents the annotated whole genome sequence of two strains of Loigolactobacillus backii, a beer-spoiling bacteria with high hop tolerance. The genetic basis and adaptation of the strains in the brewery environment were studied, revealing their ability to survive and grow in the presence of hop compounds. The findings provide insights into the mechanisms behind the tolerance of Lg. backii to extreme conditions in the brewery.

Summary: This study examined the antimicrobial and antibiofilm properties of Lactiplantibacillus pentosus L33, Lactiplantibacillus plantarum L125, and Lacticaseibacillus paracasei SP5 against clinical isolates of Staphylococcus aureus, Salmonella enterica, and Escherichia coli. The results showed that these three lactobacilli were able to inhibit the growth and biofilm formation of the pathogens. Gene expression analysis and sequence prediction also revealed their ability to produce functional bacteriocins.

Summary: This study proposes the use of freeze-dried sourdough adjuncts based on Lactiplantibacillus plantarum for making new types of sourdough breads. Three different adjuncts were used: Lactiplantibacillus plantarum alone, unfermented pomegranate juice, and pomegranate juice fermented by the same strain. The breads made with these adjuncts showed improved physicochemical, microbiological, and nutritional characteristics compared to commercial sourdough bread. The best results were obtained with the fermented pomegranate juice adjunct.

Summary: Crohn's disease (CD) and ulcerative colitis (UC) are chronic inflammatory diseases of the gastrointestinal tract. The efficacy of probiotics in treating these diseases is controversial. Our review found that probiotics were more effective in achieving or maintaining remission in ulcerative colitis compared to placebo. However, more research is needed to determine their efficacy in Crohn's disease.

Summary: In this study, a wild-type Lacticaseibacillus paracasei SP5 (L. paracasei SP5) potential probiotic strain was used to ferment an apple-orange-carrot mixed juice for 1 day. After fermentation, the juice was refrigerated at 4 degrees C and analyzed for microbiological stability, volatile characterization, physicochemical properties, sensorial validation, and viability of the probiotic strain. The stored juice showed no yeast/fungi growth and retained a viability of 8.28 Log CFU/mL of L. paracasei SP5 even after 4 weeks of cold storage. The fermented juice exhibited changes in pH, TTA, organic acids content, residual sugar content, and volatile profile. The sensorial properties of the fermented juice were positively influenced.

Summary: This research proposes a method to produce sweet wine from the by-product of high-quality Corinthian currants, involving complete fermentation and the use of alcohol-tolerant yeast. Sugar extraction from the by-product or the addition of syrup made from the by-product can adjust sweetness, and fermentation can be stopped by adding ethanol at the desired sugar level. The non-fortified wines have better characteristics (mainly in terms of acidity, antioxidant capacity, and phenolic content) than fortified wine, and adjusting sweetness using the by-product is the simplest and least costly method. This method can produce high-quality sweet wines with a characteristic fruity flavor, which can be commercialized as specialty currant beverages or liqueurs.

Summary: Among beer-spoiling microorganisms, dominant species include Lactobacillus, Leuconostoc, Oenococcus, and Pediococcus. High hydrostatic pressure can eliminate these microorganisms while preserving desired beer properties. This study analyzed the resistance of a beer-spoiling Lactiplantibacillus plantarum strain to hop and high hydrostatic pressure, and confirmed its genome characteristics through sequencing. The findings suggest the strain's growth is affected by beer concentration and it possesses genes for stress resistance and adaptation to the brewing environment.
