These structured communities exhibit enhanced resistance to antibiotics and host immune responses, making their eradication difficult. Emerging research illuminates the potential of glutathione (GSH), a crucial endogenous tripeptide, as a powerful agent in disrupting and inhibiting biofilm formation.作者：M Ghasemi·2021·被引用次数：40—The results showed that the use of curcumin in combination with AgNPs then aPDT reduced the number of bacteria in planktonic andbiofilmforms. This article delves into the growing evidence supporting glutathione's role in disrupting biofilms, its mechanisms of action, and its implications for combating persistent bacterial infections.作者：JM Thomas·2026—Here, we show that glutathione (GSH), the primary redox buffer in A. baumannii,provides broad protection against environmental stresses, ...

The fundamental investigation into whether glutathione (GSH) can act as a biofilm disruptor has yielded promising results. Studies have demonstrated that GSH is able to rapidly and comprehensively destroy P.Glutathione-gated potassium efflux as a mechanism of ... aeruginosa associated biofilms, a common and problematic colonizer in healthcare settings. Furthermore, GSH alone is sufficient to disrupt immature and mature biofilms, suggesting a direct and potent effect on established microbial communities. This capability is critical because biofilm formation is one virulence factor in P. aeruginosa, contributing to chronic infections. The ability of glutathione to mitigate quorum sensing-induced biofilm formation in specific bacterial species like *Klebsiella pneumoniae* and *Serratia marcescens* further highlights its broad-spectrum anti-biofilm potential.

The mechanisms by which glutathione disrupts the biofilms are multifaceted作者：A Manoharan·2025·被引用次数：1—NAC and the related antioxidantglutathionehave shown significant efficacy against CF P. aeruginosa isolates, both alone and in combination .... One key aspect is its role as a major intracellular redox buffer.Glutathione-Disrupted Biofilms of Clinical Pseudomonas ... This intrinsic property allows glutathione (GSH) to provide broad protection against environmental stresses that bacteria within biofilms often encounter. Research indicates that glutathione disrupts approximately 50% of Pseudomonas aeruginosa biofilms by neutralizing ROS (Reactive Oxygen Species). This disruption can occur through several pathways, including influencing the extracellular matrix佛历2567年3月28日—The current study exploresGlutathione's role in inhibiting bacterial biofilms, offering insights into its antibacterial, anti-biofilm, and anti .... For instance, glutathione-gated potassium efflux (GGKE) has been identified as a potential mechanism for active biofilm detachment. This process can impact the cross-linking of the extracellular polymeric substance (EPS), a key structural component of biofilms, leading to their destabilization.

Beyond direct disruption, glutathione enhances antibiotic efficiency and effectiveness. Biofilms significantly impede antibiotic penetration and efficacy. However, when GSH is present, it can reduce biofilm viability and potentiate the action of conventional antibiotics.This study has demonstrated thatGSH alone is sufficient to disrupt immature and mature biofilmsof clinical P. aeruginosa. DNase I enhances this effect on both ... This synergistic effect is vital for overcoming antibiotic resistance often associated with biofilms.Pseudomonas aeruginosa glutathione biosynthesis genes ... For example, studies have shown that GSH reduces biofilm viability and enhances antibiotic efficiency, with a marked concentration-dependent effect.Bioinformatics, Virtual Screening, and Biological Evaluation The combination of GSH with antibiotics can lead to a more substantial reduction in bacterial load within biofilms.

The interaction of glutathione with bacterial virulence factors also contributes to its anti-biofilm properties. In the case of *Pseudomonas aeruginosa*, the virulence factor pyocyanin can be neutralized by glutathione. Glutathione has been shown to help remove pyocyanin toxin from inside cells effectively while neutralizing it from inside the biofilm. This detoxification process can weaken the biofilm structure and reduce its overall pathogenicity.

Technological advancements are also leveraging glutathione for biofilm detection and treatment. Fluorescent glutathione-stabilized gold nanoclusters have shown promise in interacting with the extracellular matrix of bacterial biofilms, potentially aiding in their imaging and targeted destruction. Similarly, biogenic silica NPs modified with glutathione have been developed for targeting bacterial cell surfaces and biofilms, representing innovative nanotechnology approaches for combatting these recalcitrant structures.

It is important to note the complex relationship between glutathione and biofilm formation. While much research focuses on its disruptive capabilities, some studies have indicated that the Pseudomonas aeruginosa glutathione biosynthesis genes can play roles in stress protection, virulence, and indeed, biofilm formation作者：W Zhang·2014·被引用次数：12—Glutathione-gated potassium effluxhas been studied in. Escherichia coli (Bakker, 1993; Henriques and Love, 2007),. Novosphingobium capsulatum. (Ferguson et al.. For instance, deletion of genes encoding glutathione biosynthesis increases biofilm formation in *P.The Role of Glutathione in Disrupting Biofilms aeruginosa*. This suggests that the cellular production of glutathione is intimately linked to the bacteria's ability to form and maintain biofilms under certain conditions, a concept explored in "The glutathione pathway is required for biofilm formation in..." studies.The glutathione pathway is required for biofilm formation in ... However, the application of exogenous glutathione has consistently demonstrated significant anti-biofilm benefits.The Role of Glutathione in Disrupting Biofilms

In summary, the scientific community is increasingly recognizing the significant potential of glutathione in the fight against bacterial biofilms. From directly disrupting mature biofilms and inhibiting their formation to enhancing antibiotic efficacy and interacting with virulence factors, glutathione's role in inhibiting bacterial biofilms is multifaceted and promising. Further research into its precise mechanisms and optimal application strategies, potentially in combination with other agents and advanced nanotechnology, is crucial for harnessing its full therapeutic power against infection. The ongoing exploration into glutathione's role in disrupting biofilms offers a hopeful avenue for developing novel treatments for biofilm-associated diseases.
