Synthesis of Silver Nanoparticles from Ganoderma Species and Their Activity against Multi Drug Resistant Pathogens
© 2023 Wiley‐VHCA AG, Zurich, Switzerland..
The widespread and indiscriminate use of broad-spectrum antibiotics leads to microbial resistance, which causes major problems in the treatment of infectious diseases. However, advances in nanotechnology using mushrooms have opened up new domains for the synthesis and use of nanoparticles against multidrug-resistant pathogens. Mushooms have recently attracted attention and are exploited for food and medicinal purposes. The current study focuses on the molecular identification, characterization of biologically synthesized silver nanoparticles by X-ray diffraction (XRD) spectroscopy, Fourier Transform Infrared Spectroscopy (FTIR), UV-Vis spectroscopy and scanning electron microscopy (SEM) and antibacterial analysis of extract and silver nanoparticles (AgNPs) synthesis from Ganoderma resinaceum against multidrug resistant microbes. Accurate identification of mushrooms is key in utilizing them for the benefit of humans. However, morphological identification of mushrooms is time consuming, tedious and may be prone to error. Molecular techniques are quick and reliable tools that are useful in mushroom taxonomy. Blast results showed that G. resinaceum (GU451247) obtained from Pakistan was 97 % same to the recognized G. resinaceum (GU451247) obtained from China as well as G. resinaceum (GU451247) obtained from India. The antimicrobial potential of mushroom composite and AgNPs showed high efficacy against pathogenic Staphylococcus aureus (ZOI 23 mm) K. pneumonia (ZOI 20 mm), Pseudomonas aeruginosa (ZOI 24 mm) and E. fecalis and A. baumannii (ZOI 10 mm), and multidrug resistant (MDR) A. baumannii (ZOI 24 mm). XRD evaluation revealed the crystalline composition of synthesized NPs with diameter of 45 nm. UV-Vis spectroscopy obsorption peaked of 589 nm confirmed the presence of AgNPs. SEM results showed the cubic morphology of AgNPs. The FTIR analysis of NPs obtained from G. resinaceum containing C=O as well as (O=C-H) stretching revealed presence of hydrogen, carbonyl and amide groups. The synthesized extract and AgNPs showed promising minimum inhibitory concentration (MIC) at 2 mg concentration against the MDR strains. AgNPs are observed to be efficient as they need less quantities to prevent bacterial growth. In the view of challenges for developing antimicrobial NPs of variable shape and size by various other methods, tuning nanoparticles synthesized via mushrooms can be a wonderful approach to resolve existing hurdles.
