Nanoparticles as biomedicine has made a crucial role in health biotechnology. Different transition metals various forms playing nanotechnological advances and biological applications. Silver one of the nontoxic, safe inorganic antibacterial agents can serve replacement antibiotics. Present research is based on biogenic synthesis silver nanoparticles (Ag-NPs) potential antibiotics from fungal metabolites Penicillium oxalicum. We used different analytical techniques X-ray diffraction (XRD) scanning electron microscopy (SEM) for characterization biosynthesized nanoparticles. Furthermore, activity was checked against Staphylococcus aureus, S. dysenteriae, Salmonella typhi by using well diffusion method UV visible spectrophotometer. Maximum zone inhibition recorded Shigella dysenteriae 17.5 ± 0.5 mm (mm) both species 18.3 0.60 typhi. The P. oxalicum showed excellent activity. It concluded our results that have significant might be useful wide range applications such bactericidal agent resistant bacteria, preventing infections, healing wounds, anti-inflammation.

Abstract In the current investigation, 16 samples of six species genus Polygonatum were collected from different geographical regions in China. Leaf micromorphological traits studied detail using scanning electron microscopy. About five‐leaf used for each regions. A significant variation was found foliar epidermal such as stomata types and their distribution, cell shape, anticlinal wall pattern, various trichomes. Polygonal cells observed P. cyrtonema , odoratum sibiricum filipes rectangular P . zanlanscianense irregular shape Straight pattern most species, but straight to little undulate Similarly, that are, oval, oblong, elliptical is, paracytic, anomocytic, actinocytic have been observed. Based on traits, closely related one another. On other hand, involucratum shows a strong association However, showed very less similarity with five species. Hence this study adds useful information may be helpful further taxonomic classification taxa at subspecies level correct identification discrimination

Abstract Lamioideae comprised the second‐largest subfamily in Lamiaceae. Although considerable progress has recently been made taxonomic study of Lamioideae, remains one most poorly investigated Therefore, present was designed with aim to document pollen micromorphology some selected taxa and its significance from Pakistan. Pollen micromorphological features were observed using scanning electron microscopy. The grains are monad, tricolpate, radially/bilateral symmetrical. small medium‐sized having oblate, oblate/subspheroidal, subspheroidal shape. Exine sculpturing as reticulate, microreticulate, bireticulate. colpus surface ornamentation found verrucate, gemmate, scabrate, psilate. There a variation between species micromorphology, that is, coarseness reticulum, thickness muri comprising reticulum number secondary lumina per primary lumen. Hence, this documented morphology Pakistan strengthens identification based on characters, which helps correct identification, discrimination at generic level.
