Abstract
Natural plant extracts have demonstrated significant potential in alternative antibiotic therapies. Cinnamaldehyde (CA) has garnered considerable attention as a natural antibacterial agent. In this study, Tandem mass tag (TMT) quantitative proteomics combined with Western blot and RT-qPCR methods were employed to explore the antibacterial mechanism of CA against Methicillin-Resistant Staphylococcus aureus (MRSA) at the protein level. The results showed that a total of 254 differentially expressed proteins (DEPs) were identified in the control group and CA treatment group, of which 161 were significantly upregulated and 93 were significantly downregulated. DEPs related to nucleotide synthesis, homeostasis of the internal environment, and protein biosynthesis were significantly upregulated, while DEPs involved in the cell wall, cell membrane, and virulence factors were significantly downregulated. The results of GO and KEGG enrichment analyses demonstrated that CA could exert its antibacterial effects by influencing pyruvate metabolism, the tricarboxylic acid (TCA) cycle, teichoic acid biosynthesis, and the Staphylococcus aureus (S. aureus) infection pathway in MRSA. CA significantly inhibited the expression of recombinant protein MgrA (p < 0.05), significantly reduced the mRNA transcription levels of mgrA, hla, and sdrD genes (p < 0.05), and thermostability migration assays demonstrated that CA can directly interact with MgrA protein, thereby inhibiting its activity. These findings suggest that CA exerts its antibacterial mechanism by regulating the expression of related proteins, providing a theoretical basis for further development of clinical applications of antimicrobial agents derived from natural plant essential oils in the treatment of dairy cow mastitis.

HR2 under combined stress conditions. JOURNAL OF HAZARDOUS MATERIALS 2024; 465:133242. [PMID: 38103289 DOI: 10.1016/j.jhazmat.2023.133242] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/07/2023] [Revised: 12/08/2023] [Accepted: 12/10/2023] [Indexed: 12/19/2023]
Abstract
The resuscitated strains achieved through the addition of resuscitation promoting factor (Rpf) hold significant promise as bio-inoculants for enhancing the bioremediation of polychlorinated biphenyls (PCBs). Nevertheless, the potential of these resuscitated strains to transition into a viable but non-culturable (VBNC) state, along with the specific stressors that initiate this transformation, remains to be comprehensively elucidated. In this study, a resuscitated strain HR2, obtained through Rpf amendment, was employed to investigate its survival strategies under combined stress involving low temperature (LT), and PCBs, in the absence and presence of heavy metals (HMs). Whole-genome analysis demonstrated that HR2, affiliated with Achromobacter, possessed 107 genes associated with the degradation of polycyclic aromatic compounds. Remarkably, HR2 exhibited effective degradation of Aroclor 1242 and robust resistance to stress induced by LT and PCBs, while maintaining its culturability. However, when exposed to the combined stress of LT, PCBs, and HMs, HR2 entered the VBNC state. This state was characterized by significant decreases in enzyme activities and notable morphological, physiological, and molecular alterations compared to normal cells. These findings uncovered the survival status of resuscitated strains under stressful conditions, thereby offering valuable insights for the development of effective bioremediation strategies.

ENVIRONMENTAL POLLUTION (BARKING, ESSEX : 1987) 2024; 344:123320. [PMID: 38185359 DOI: 10.1016/j.envpol.2024.123320] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/30/2023] [Revised: 01/03/2024] [Accepted: 01/04/2024] [Indexed: 01/09/2024]
Abstract
The exploration of resuscitated strains, facilitated by the resuscitation promoting factor (Rpf), has substantially expanded the pool of cultivated degraders, enhancing the screening of bio-inoculants for bioremediation applications. However, it remains unknown whether these resuscitated strains can re-enter the viable but non-culturable (VBNC) state and the specific stress conditions that trigger such a transition. In this work, the whole genome, and polychlorinated biphenyl (PCB)-degrading capabilities of a resuscitated strain HR1, were investigated. Notably, the focus of this exploration was on elucidating whether HR1 would undergo a transition into the VBNC state when exposed to low temperature and PCBs, with and without the presence of heavy metals (HMs). The results suggested that the resuscitated strain Pseudomonas sp. HR1 harbored various functional genes related to xenobiotic biodegradation, demonstrating remarkable efficiency in Aroclor 1242 degradation and strong resistance against stress induced by low temperature and PCBs. Nevertheless, when exposed to the combined stress of low temperature, PCBs, and HMs, HR1 underwent a transition into the VBNC state. This transition was characterized by significant decreases in enzyme activities and notable changes in both morphological and physiological traits when compared to normal cells. Gene expression analysis revealed molecular shifts underlying the VBNC state, with down-regulated genes showed differential expression across multiple pathways and functions, including oxidative phosphorylation, glycolysis, tricarboxylic acid cycle, amino acid metabolism, translation and cytoplasm, while up-regulated genes predominantly associated with transcription regulation, membrane function, quorum sensing, and transporter activity. These findings highlighted the great potential of resuscitated strains as bio-inoculants in bioaugmentation and shed light on the survival mechanisms of functional strains under stressful conditions, which should be carefully considered during bioremediation processes.

Abstract
Water pollution causes the propagation of pathogenic microorganisms, which poses a serious threat to human life. Escherichia coli O157:H7, as a representative organism that can directly exhibit molecular response to stress, was selected as the indicator bacteria for the study. Tandem mass tag (TMT) quantitative proteomics and non-targeted metabolomics were used to study the response of Escherichia coli O157:H7 to Aronia melanocarpa anthocyanin (AMA) treatment. The results showed that 628 proteins and 1338 metabolites changed significantly after treatment with AMAs. According to bioinformatics analysis, integrated proteomics and metabolomics analysis differentially expressed proteins (DEPs) and metabolites participate in pyruvate metabolism, glycolysis/gluconeogenesis, alanine, aspartate and glutamate metabolism and the pentose phosphate pathway. This study preliminarily proposed the inhibition mechanism of AMAs on Escherichia coli O157:H7 from the perspective of multi-omics, providing a theoretical basis for the application of natural preservatives in fresh cut vegetables.

Abstract
The increasing global meat demand raises concerns regarding the spoilage of meat caused by microbial invasion and oxidative decomposition. Natural substances, as a gift from nature to humanity, possess broad-spectrum bioactivity and have been utilized for meat preservation. However, their limited stability, solubility, and availability hinder their further development. To address this predicament, advanced organic nanocarriers provide an effective shelter for the formation of nano-natural substances (NNS). This review comprehensively presents various natural substances derived from plants, animals, and microorganisms, along with the challenges they face. Subsequently, the potential of organic nanocarriers is explored, highlighting their distinct features and applicability, in addressing these challenges. The review methodically examines the application of NNS in meat preservation, with a focus on their pathways of action and preservation mechanisms. Furthermore, the outlook and future trends for NNS applications in meat preservation are concluded. The theory and practice summary of NNS is expected to serve as a catalyst for advancements that enhance meat security, promote human health, and contribute to sustainable development.

Abstract
Hexanal is a phytochemical with antimicrobial activity. However, its antibacterial effect and mechanism against Vibrio parahaemolyticus (V. parahaemolyticus) remain unclear. The study aims to elucidate the associated mechanism using tandem mass tag quantitative proteomics and non-targeted metabolomics. Hexanal treatment reduced intracellular ATP concentration, increased membrane permeability, and destroyed the morphology and ultrastructure of V. parahaemolyticus cells. Proteomics and metabolomics data indicated that 572 differentially expressed proteins (DEPs) and 241 differential metabolites (DMs) were identified in hexanal-treated V. parahaemolyticus. These DEPs and DMs were involved in multiple biological pathways including amino acid metabolism, purine and pyrimidine biosynthesis, etc. Bioinformatics analysis revealed that hexanal damaged the structure and function of cell membranes, inhibited nucleotide metabolism, and disturbed carbohydrate metabolism and tricarboxylic acid cycle (TCA) cycle, which ultimately resulted in growth inhibition and bacterial death. The study is conducive to better understand the mode of action of hexanal against V. parahaemolyticus and offers experimental foundation for the application of hexanal as the antibacterial agent in the seafood-associated industry.
