Alcaligenes faecalis ZD02, a Novel Nematicidal Bacterium with an Extracellular Serine Protease Virulence Factor.

ABSTRACT: Root knot nematodes (RKNs) are the world's most damaging plant-parasitic nematodes (PPNs), and they can infect almost all crops. At present, harmful chemical nematicides are applied to control RKNs. Using microbial nematicides has been proposed as a better management strategy than chemical control. In this study, we describe a novel nematicidal bacterium named Alcaligenes faecalis ZD02. A. faecalis ZD02 was isolated from Caenorhabditis elegans cadavers and has nematostatic and nematicidal activity, as confirmed by C. elegans growth assay and life span assay. In addition, A. faecalis ZD02 fermentation broth showed toxicity against C. elegans and Meloidogyne incognita. To identify the nematicidal virulence factor, the genome of strain ZD02 was sequenced. By comparing all of the predicted pro
