“…This shows that the stress resistance of C. pilosula is low in the summer and enhanced in the autumn [70][71][72]. Zhang et al [73] showed that MDA has antibacterial properties against bacteria such as Staphylococcus and Lactobacillus. Bacteria, such as Exiguobacterium and Nitrospira, play an important role in improving stress resistance and biodegradation in plants [74][75][76].…”

Codonopsis pilosula is a medicinal and edible herb with a rich nutritional value. In Gansu Province, China, its production quality and yield differ during the four seasons. Here, we investigated the differences in the microfloral composition and metabolic functions in the rhizospheric soil and roots of C. pilosula during the four seasons, and we also analyzed their dynamic and synergistic effects on C. pilosula growth and carbohydrate content change. The C. pilosula samples were analyzed for plant physiology, microfloral composition and metabolic functions in the rhizospheric soil and roots using high-throughput sequencing technology. Environmental indices including soil physiochemistry and meteorological conditions were also determined by the coupled chromatography–spectroscopy technique. The results revealed that the C. pilosula growth was affected by temperature, precipitation and light intensity, with the bacterial structures and functions of the soil and root samples showing obvious seasonal changes. Due to the diversity of microbial composition and community metabolic function, and the synergistic effect of microbial and environmental factors, there are significant differences in stress resistance, physiological status and metabolites of C. pilosula in different seasons. Furthermore, the change in seasons was significantly correlated with the quality and yield of C. pilosula. This study provides a scientific basis for soil improvement and the refinement of local Radix C. pilosula cultivation methods.

“…The release of intracellular nutrients might be the primary mechanism of microbial inactivation. On the other hand, unsaturated lipid acids on the cell membrane could be rapidly oxidized to peroxides such as MDA when damaged due to the presence of CC. , MDA accumulation led to oxidative stress and cross-linking reactions, exacerbating cell membrane damage . As demonstrated in Figure B, MDA accumulation in response to UnCA activation indicated the lipid peroxidation of the cell membrane and would continue to oxidize the lipid and protein on the cell membrane.…”

The anaerobically fermented medium chain carboxylic acid (MCCA) has been demonstrated to inhibit methanogenesis in an anaerobic chain elongation fermentation system. However, the inhibition mechanism and recovery performance remain unknown. This study systematically investigated the shortterm effects of undissociated n-caproic acid (UnCA) on methanogenesis in granular sludge, focusing on methane anabolism and community structure. Results showed that 2.0 mM UnCA inhibited CH 4 yield by 94.3% and acetate consumption by 88.8%, which was ascribed to the variations of intracellular H + and cell membrane damage. Specifically, UnCA altered multiple processes of methane anabolism such as energy metabolism and electron transport by increasing the intracellular H + level. In addition, the hydrophobicity of UnCA destroyed the integrity of the cell membrane. However, the methane synthesis enzymes appeared not to be affected as indicated by the stable abundance and activities and also the subsequent reversible 66.6−82.8% recovery of the CH 4 yield. Meanwhile, the UnCA supplementation transformed the dominant species from acetoclastic methanogenic to hydrogenotrophic ones and also enriched Bathyarchaeia which had potential CH 4 production capacity. These findings are expected to enhance the understanding of the MCCA inhibition on methanogenesis, promoting the establishment of an efficient and stable MCCA production system.

Biofilms formed by multidrug resistant (MDR) bacteria like methicillin-resistant Staphylococcus aureus (MRSA) and others are the main causes of infections that represent a serious public health issue. Persistent MDR infections are mostly derived from biofilm formation which in turn leads to resistance to conventional antimicrobial therapy. Inhibition of bacterial surface attachment is the new alternative strategy without affecting the bacterial growth. Thus, the discovery of compounds that interfere with biofilm production, virulence factors release and quorum sensing (QS) detection in pathogens is a promising processus. Among these compounds, natural and synthetic molecules are a compelling alternative to attenuate pathogenicity. The combination of these compounds with antibiotics makes the bacteria more vulnerable to the later, once used alone. This combination can restore antibiotic effectiveness against MDR bacteria. Among these molecules, 3-phenylpropan-1-amine (3-PPA) has been found to inhibit Serratia marcescens biofilm formation, PAβN has been proven to inhibit biofilm prodcution in A. baumannii, while brominated Furanone C-30 has been reported to be a potent inhibitor of the QS system and P. aeruginosa biofilm. Therefore, the combination between biofilm-inhibitors and antibiotics represents a promising strategy to mitigate antibiotic resistance in MDR pathogens, which has become a major threat to public healthcare around the globe.
