Fig. 3From: Antibiofilm activity of biosynthesized silver and copper nanoparticles using Streptomyces S29Characterization of Streptomyces isolate S29; (a) Phylogenetic tree of Streptomyces S29 based on sequence alignment of 16S rRNA gene of isolate S29 and other Streptomyces species. The phylogenetic tree was constructed using the neighbor-joining method of MEGA 7.0 (b) SEM figures of Streptomyces isolate S29 indicating spiral spore chains with smooth surfacesBack to article page
