Photorhabdus luminescens, an entomopathogenic bacterium and nematode symbiont, has homologues of the Hca and Mhp enzymes. In Escherichia coli, these enzymes catalyze the degradation of the aromatic compounds 3-phenylpropionate (3PP) and cinnamic acid (CA) and allow the use of 3PP as sole carbon source. P. luminescens is not able to use 3PP and CA as sole carbon sources but can degrade them. Hca...

The present study was undertaken to test the efficacy of culture extracts of five Penicillium species viz. P. citrinum, P. digitatum, P. expansum, P. verrucosum and P. viridicatum against five different soilborne bacteria namely Salmonella gallinarum, Xenorhabdus luminescens, Xanthobacter autotrophicus, Acetobacter xylinum and Carnobacterium mobile. The species of Penicillum showed marked antib...

A sequenced collection of plasmid-borne random fusions of Escherichia coli DNA to a Photorhabdus luminescens luxCDABE reporter was used as a starting point to select a set of 689 nonredundant functional gene fusions. This group, called LuxArray 1.0, represented 27% of the predicted transcriptional units in E. coli. High-density printing of the LuxArray 1.0 reporter strains to membranes on agar ...

In this study, we assessed pirAB toxin transcription in Photorhabdus luminescens laumondii (strain TT01) (Enterobacteriaceae) by comparing mRNA abundance under in vivo and in vitro conditions. In vivo assays considered both natural and forced infections with two lepidopteran hosts: Galleria mellonella and Manduca sexta. Three portals of entry were utilized for the forced infection assays: (a) i...
