The regulatory elements for nosiheptide biosynthesis were identified by a novel host-vector system with an endogenous gene within the biosynthetic gene cluster as a reporter gene. The present study offers a rapid and reliable method for the identification of regulatory elements in the biosynthesis of various bioactive natural products.

background: to develop a new green approach for biosynthesis of silver nanoparticles, myconanotechnology has been represented as a novel field of study in nanotechnology. in this study, we have reported the extracellular synthesis of highly stable silver nanoparticles using three species of dermatophytes: trichophyton rubrum, trichophyton mentagrophytes and microsporum canis. methods: clinical ...

Heavy metal (HMs) pollution is currently one of the serious issues for the environment and agriculture as it has a direct impact on the production yield. This situation has gained a rapid momentum in the present era due to the population pressure, industrialization, and various anthropogenic activities which in turn lead to oxidative ...

nowadays, green chemistry and its advantages are generating interest of researchers toward ecofriendly biosynthesis of the metallic nanoparticles. in this research, a rapid, simple and green method was developed for the synthesis of silver nanoparticles using aqueous extract of prangos ferulaceae leaves. the synthesized silver nanoparticles were characterized by uv-vis spectroscopy, scanning el...

We recently reported that the marked decrease in cellular ceramide in primary astrocytes is an early event associated with the mitogenic activity of basic fibroblast growth factor (bFGF) (Riboni, L., Viani, P., Bassi, R., Stabieini, A., and Tettamanti, G. (2000) GLIA 32, 137-145). Here we show that a rapid activation of sphingomyelin biosynthesis appears to be the major mechanism responsible fo...
