“…The endosymbiotic relation of this strain with plants has also been reported by Rodríguez-Medina et al [36]. K. oxytoca and K. pneumoniae are associated with plants in host-plant association by fixing nitrogen acting as diazotrophs attaching themselves with the root nodules thus increasing agricultural yield [37]. E. cloacae are used to enhance the seed germination and growth attributes in rice crops by using a substitute of ammonium sulfate as ACC [38].…”

Aims: This study aimed to evaluate the genetic and functional diversity of bacteria associated with the surfaces of Prunus persica (L.) Batsch. Methodology: A total of 15 peach samples from various areas of Lahore city were collected and processed according to standard microbiological protocols. The final taxonomic status of bacterial strains was confirmed by 16S rRNA gene sequencing. Bacterial strains were screened for plant growth-promoting attributes that included auxin production, phosphate, and zinc solubilization, and hydrogen cyanide (HCN) production. Antimicrobial activity of strains was also evaluated. In pot trials, strains were evaluated for their role to enhance plant growth. Results: Analysis showed that bacterial isolates belonged to Bacillus, Staphylococcus, Klebsiella, Enterobacter, and Providencia genera. A strain KS 22 of Staphylococcus sciuri showed the highest production of auxin. In terms of antibiotic susceptibility, B. aerius KS 8 exhibited a pattern of sensitivity toward norfloxacin, amoxicillin, and clavulanic acid. For pot trials with cauliflower under laboratory conditions, S. sciuri KS 22 showed 3.1 folds increase in shoot length. In the case of tomato, P. rettgeri KS 23 recorded around 1.8 folds increase in shoot length over water-treated control. On the other hand, for cauliflower, around 1.3 folds increase in root length was exhibited by B. aerius KS 8, P. rettgeri KS 23, and E. cloacae KS 29. For tomato, B. aerius KS 8 showed 1.6 folds increase in root length in comparison to control. Under natural conditions, for cauliflower, the highest increase in shoot length was exhibited by P. rettgeri KS 23 and E. cloacae KS 29. Conclusion: Finally, it has been concluded that bacterial strains B. aerius KS 8, S. haemolyticus KS 9, S. sciuri KS 22, P. rettgeri KS 23, and E. cloacae KS 29 exhibited plant growth promotion in pot trials.

“…Studies on quorum sensing inhibition and the quest for QS inhibitors have shown plants to produce anti-QS substances. Several anti-QS methods have been used, including natural products from plant-based secondary metabolites (Berde et al, 2019). Carbohydrate derived fulvic acid (CHD-FA) 82 from pure form of fulvic acid is obtained from humic substances, also exhibits anti-biofilm activity against C. albicans (Sherry et al, 2012;Borghi et al, 2015).…”

In recent years, the demand for novel antifungal therapies has increased several- folds due to its potential to treat severe biofilm-associated infections. Biofilms are made by the sessile microorganisms attached to the abiotic or biotic surfaces, enclosed in a matrix of exopolymeric substances. This results in new phenotypic characteristics and intrinsic resistance from both host immune response and antimicrobial drugs. Candida albicans biofilm is a complex association of hyphal cells that are associated with both abiotic and animal tissues. It is an invasive fungal infection and acts as an important virulent factor. The challenges linked with biofilm-associated diseases have urged scientists to uncover the factors responsible for the formation and maturation of biofilm. Several strategies have been developed that could be adopted to eradicate biofilm-associated infections. This article presents an overview of the role of C. albicans biofilm in its pathogenicity, challenges it poses and threats associated with its formation. Further, it discusses strategies that are currently available or under development targeting prostaglandins, quorum-sensing, changing surface properties of biomedical devices, natural scaffolds, and small molecule-based chemical approaches to combat the threat of C. albicans biofilm. This review also highlights the recent developments in finding ways to increase the penetration of drugs into the extracellular matrix of biofilm using different nanomaterials against C. albicans.

“…Various plant extracts, including Rhodiola crenulata , Epimedium brevicornum , Dolichos lablab , Polygonum cuspidatum, and Malus pumila, have demonstrated anti-biofilm activity. Extracts of E. brevicornum and P. cuspidatum and their most active components, resveratrol and icariin, showed potent anti-biofilm activity, even when applied below their MIC concentrations [ 196 , 197 ].…”

Biofilm formation on surfaces via microbial colonization causes infections and has become a major health issue globally. The biofilm lifestyle provides resistance to environmental stresses and antimicrobial therapies. Biofilms can cause several chronic conditions, and effective treatment has become a challenge due to increased antimicrobial resistance. Antibiotics available for treating biofilm-associated infections are generally not very effective and require high doses that may cause toxicity in the host. Therefore, it is essential to study and develop efficient anti-biofilm strategies that can significantly reduce the rate of biofilm-associated healthcare problems. In this context, some effective combating strategies with potential anti-biofilm agents, including plant extracts, peptides, enzymes, lantibiotics, chelating agents, biosurfactants, polysaccharides, organic, inorganic, and metal nanoparticles, etc., have been reviewed to overcome biofilm-associated healthcare problems. From their extensive literature survey, it can be concluded that these molecules with considerable structural alterations might be applied to the treatment of biofilm-associated infections, by evaluating their significant delivery to the target site of the host. To design effective anti-biofilm molecules, it must be assured that the minimum inhibitory concentrations of these anti-biofilm compounds can eradicate biofilm-associated infections without causing toxic effects at a significant rate.
