CTAB Method for Genomic DNA Extraction from Nonomuraea

Kui Hong

Abstract

In order to obtain genomic DNA which meets the requirements of DNA-DNA hybridization,CTAB method combined with liquid nitrogen grinding was investigated.Cultures from different media added with glycine were harvested in different time.Quality of extracted genomic DNA was assessed by electrophoresis and OD260/OD280 value.Mycelia of shaking culture in yeast extract malt extract(YE) medium containing 0.3% glycine for 3 days were subjected for DNA extraction.The genomic DNA obtained was about 20 kb,with the OD260/OD280 value around 1.8.
