“…In addition, as an important part of the TCA cycle, malic acid can directly regulate the metabolism of carbohydrates and proteins through this biochemical reaction ( Li M. et al, 2020 ). Two differential metabolites (i.e., malic acid and isocitrate) caused by glucose are involved in the TCA cycle and glyoxylate and dicarboxylate metabolism, which are reported to be related with carbohydrate metabolism ( Ruan et al, 2021 ). According to the correlation analysis, bacteria associated with malic and isocitrate included Pseudomonadales , Acinetobacter , Pelomonas , and Lactobacillus reuteri , suggesting that these microorganisms might be potential targets for regulating carbohydrate metabolism during silage.…”

This study was conducted to investigate the effects of different additives on the fermentation quality, nutrient composition, bacterial communities, and metabolic profiles of the silage of hybrid Pennisetum. The experiment was conducted using five treatments, i.e., CK, control group, MA, 1% malic acid of fresh matter (FM) basis, GL, 1% glucose of FM basis, CE, 100 U/g FM cellulase, and BS, 106 cfu/g FM Bacillus subtilis, with six replicates each treatment. After a 120-day fermentation, 30 silage packages were opened for subsequent determination. As a result, all four additives had positive effects on the fermentation quality and nutrient composition of the silage of hybrid Pennisetum. The high-throughput sequencing of V3–V4 regions in 16S rRNA was performed, and results showed that Firmicutes and Proteobacteria were the dominant phyla and that Aquabacterium and Bacillus were the dominant genera. MA, GL, CE, and BS treatment resulted in 129, 21, 25, and 40 differential bacteria, respectively. The four additives upregulated Bacillus smithii but downregulated Lactobacillus rossiae. Metabolic profiles were determined by UHPLC-Q/TOF-MS technology and the differential metabolites caused by the four additives were 47, 13, 47, and 18, respectively. These metabolites played antioxidant, antibacterial, and anti-inflammatory functions and involved in pathways, such as the citrate cycle, carbon fixation in photosynthetic organisms, and glyoxylate and dicarboxylate metabolism. In conclusion, silage additives promoted fermentation quality and nutrient composition by altering bacterial communities and metabolic profiles. This study provided potential biomarkers for the improvement of silage quality.

“…As a result, MOEO demonstrated excellent suppression of biofilm formation. Cao et al (2021) and Ruan et al (2021) found that citral essential oil and resveratrol can suppress the biofilm formation in V. parahaemolyticus and E. coli. The biofilm formation in the control group decreased at 36 h may arise from cell apoptosis cutting down the amounts of bacteria that can form biofilms.…”

The study was to evaluate the antimicrobial impacts on Melissa officinalis L. essential oil (MOEO) against Vibrio parahaemolyticus. The minimum inhibitory concentration (MIC) of MOEO on Vibrio parahaemolyticus was 1 μL⋅mL–1. The kill-time curve exhibited that MOEO had good antimicrobial activity. The analysis of cellular ingredients leakage and cell viability illustrated that MOEO has destruction to the morphology of the cell membrane. The damage to the membrane integrity by MOEO has been confirmed by transmission and scanning electron microscopy, obvious morphological and ultrastructural changes were observed in the treated bacterial cells. The MOEO at 0.5 μL⋅mL–1 can inhibit the biofilm formation, biofilm motility, and extracellular polysaccharide production. Meanwhile, the qPCR results exhibited MOEO inhibited the expression of virulence genes. The findings showed that MOEO exerted its antimicrobial effect mainly by destroying the membrane, which indicated its potential as a natural food preservative.

“…It has been reviewed that the adhesion of pathogenic bacteria on intestinal epithelium is related to the formation of bacteria biofilm ( 126 ). Interestingly, resveratrol restrains the growth of avian pathogenic E. coli through inhibiting the formation of bacterial biofilm, and the MIC is 128 μg/ml ( 97 ). It has been found that the adhesion inhibition of E. coli O157:H7 to HT-29 colonic cells is more than 60% with resveratrol and its derivatives treatments ( 127 ).…”

The integrity of intestinal barrier determines intestinal homeostasis, which could be affected by various factors, like physical, chemical, and biological stimuli. Therefore, it is of considerable interest and importance to maintain intestinal barrier function. Fortunately, many plant polyphenols, including resveratrol, could affect the health of intestinal barrier. Resveratrol has many biological functions, such as antioxidant, anti-inflammation, anti-tumor, and anti-cardiovascular diseases. Accumulating studies have shown that resveratrol affects intestinal tight junction, microbial composition, and inflammation. In this review, we summarize the effects of resveratrol on intestinal barriers as well as the potential mechanisms (e.g., inhibiting the growth of pathogenic bacteria and fungi, regulating the expression of tight junction proteins, and increasing anti-inflammatory T cells while reducing pro-inflammatory T cells), and highlight the applications of resveratrol in ameliorating various intestinal diseases.
