Anti-biofilm Activity Against Gram-Positive Bacteria by Biologically Synthesized Silver Nanoparticles Using Curcuma longa.

Objective: To assess the biofilm inhibition activity of biosynthesized silver nanoparticles (AgNPs) using Curcuma longa.

Method: Characterizations of these biogenic nanoparticles were done by UV-Vis spectroscopy, TEM, EDX and nanoparticles tracking analyzer. The antibiofilm activity of AgNPs against S.

A rapid and inexpensive one-tube genomic DNA extraction method from Agrobacterium tumefaciens.

Many methods have been used to isolate genomic DNA, but some of them are time-consuming and costly, especially when extracting a large number of samples. Here we described an easy protocol using two simple solutions for DNA extraction from A. tumefaciens cells.
