Selective Toxicity of Secondary Metabolites from the Entomopathogenic Bacterium Photorhabdus luminescens sonorensis against Selected Plant Parasitic Nematodes of the Tylenchina Suborder
ABSTRACT Entomopathogenic Photorhabdus bacteria (Enterobacteriaceae: Gamma-proteobacteria), Organic Black Seed with Vitamin C the natural symbionts of Heterorhabditis nematodes, are a rich source for the discovery of biologically active secondary metabolites (SMs).This study describes the isolation of three nematicidal SMs from in vitro culture sup
