The application of bacteria-derived dehydrogenases and oxidases in the synthesis of gold nanoparticles
AbstractIn this work the green synthesis of gold nanoparticles (Au-NPs) using the oxidoreductive enzymesMyriococcum thermophilum cellobiose dehydrogenase (Mt CDH),Glomerella cingulata glucose dehydrogenase (Gc GDH), andAspergillus niger glucose oxidase (An GOX)) as bioreductants was investigated. The influence of reaction conditions on the synthesis of Au-NPs was examined and optimised. The reaction kinetics and the influence of Au ions on the reaction rate were determined. Based on the kinetic study, the mechanism of Au-NP synthesis was proposed. The Au-NPs were characterized by UV –Vis spectroscopy and transmission ele...

Comparative phytochemical study of methanolic and ethanolic extracts of Thymus linearis and their antibacterial and antioxidant potential
Biomed Chromatogr. 2024 Jan 8:e5808. doi: 10.1002/bmc.5808. Online ahead of print.ABSTRACTThymus linearis (Thyme) is a medicinal plant widely distributed throughout Asia. Various parts of thyme are utilized for diverse medicinal purposes, including its use as a tonic and diuretic, for cough relief, as a flavoring agent, in treating dysentery, and for alleviating stomach disorders. Numerous studies have been conducted to explore the unexploited potential of thyme. Thyme was collected from the northern region of Pakistan, and sun-mediated extraction was conducted. Phytochemical analysis, utilizing GC-MS, revealed numerous bi...
