A Comprehensive Review on Exploring the Potential of Phytochemicals and Biogenic Nanoparticles for the Treatment of Antimicrobial-Resistant Pathogenic Bacteria.

Antimicrobial resistance (AMR) is an escalating global health concern that results in approximately 700,000 deaths annually owing to drug-resistant infections. It compromises the effectiveness of conventional antibiotics, as well as fundamental medical procedures, such as surgery and cancer treatment. Phytochemicals, natural plant constituents, and biogenic nanoparticles synthesized through biological processes are pharmacological alternatives for supplementing or replacing traditional antibiotics.

Microbial siderophores as molecular shuttles for metal cations: sources, sinks and application perspectives.

Iron is one of the highly abundant elements on the earth's crust, an essential micronutrient for a majority of life forms, and exists in two frequent oxidation states such as ferrous (Fe) and ferric (Fe). These two oxidation states are interconvertible by redox reactions and form complexes with a wide range of siderophores. At neutral pH in soil, Fe is highly soluble upto 100 mM but have less biological value, whereas Fe is less soluble upto 10 M.

Development of siderophore-based rhizobacterial consortium for the mitigation of biotic and abiotic environmental stresses in tomatoes: An in vitro and in planta approach.

Aim: Tomato-associated plant-growth-promoting rhizosphere bacteria were screened for effective antagonistic activity against the fungal vascular wilt pathogens; tolerance to heavy metals; and enhancing the bioavailability of iron for tomato plants through in vitro and in vivo approaches.

Methods And Results: Among the 121 rhizobacteria screened for siderophores, 25 isolates were observed to be siderophore producers and out of these, seven isolates chelate copper and iron thus exhibiting in vitro antagonism against the virulent strains of Fusarium oxysporum f. sp.

Particle size influence on the composition of sugars in corncob hemicellulose hydrolysate for xylose fermentation by Meyerozyma caribbica.

The xylitol production was performed with acidophilic Meyerozyma caribbica. The particle size of 0.02 ± 0.

Antifungal activity and molecular docking of phenol, 2,4-bis(1,1-dimethylethyl) produced by plant growth-promoting actinobacterium Kutzneria sp. strain TSII from mangrove sediments.

The present study reveals the plant growth-promoting (PGP) potentials and characterizes the antifungal metabolites of Kutzneria sp. strain TSII isolated from mangrove sediment soil through in vitro and in silico studies. In this study, Kutzneria sp.

Fatty Acid Methyl Esters From the Coral-Associated Bacterium Inhibit Virulence and Biofilm Phenotypes in Multidrug Resistant : An Approach.

In an attempt to study the antibacterial, antivirulence and antibiofilm potentials of bacteria residing the tissue and surface mucus layers of the pristine corals, we screened a total of 43 distinct bacterial morphotypes from the coral sp. Among the isolates, strain CBMGL12 with showed antibacterial, antivirulence and antibiofilm activity against multidrug resistant pathogenic strains of (reference strain: MTCC96; community-acquired methicillin resistant strain: CA-MRSA). Extracellular products (ECP) from the coral-associated bacterium were solvent extracted, fractionated by chromatographic techniques such as silica column and HPLC-UV with concomitant bioassays guiding the fractionation of metabolites.

In vitro screening and in silico prediction of antifungal metabolites from rhizobacterium Achromobacter kerstersii JKP9.

The main objective of this study was to identify the antifungal metabolites from Achromobacter kerstersii JKP9, a rhizosphere bacterium isolated from tomato cultivations, inhibiting the melanin biosynthetic pathways in vascular wilt pathogen Fusarium oxysporum f. sp. lycopersici (Fol).
