Publikováno v: Irrigation Science. 31:631-642

The effect of microbial colonization on the function and rejuvenation of slow sand filters was investigated using culture-independent profiling. Colonization resulted in significant reduction in filter pore size, which may be important in order to fu

Low temperature-induced insecticidal activity ofYersinia enterocolitica

Autor: Denise Ilgen, Geraldine Bresolin, J. Alun W. Morgan, Siegfried Scherer, Thilo M. Fuchs

Publikováno v: Molecular Microbiology. 59:503-512

The insecticidal toxin complexes (Tcs) are produced by several Enterobacteriaceae associated with insects, such as Photorhabdus luminescens, Serratia entomophila and Xenorhabdus nematophilus. Genome sequences revealed tc-like genes in Yersinia spp.,

Interactions of Insecticidal Toxin Gene Products from Xenorhabdus nematophilus PMFI296

Autor: Martin J. Sergeant, Paul Jarrett, J. Alun W. Morgan, Margaret Ousley

Publikováno v: Applied and Environmental Microbiology. 69:3344-3349

Four genes on a genomic fragment from Xenorhabdus nematophilus PMFI296 were shown to be involved in insecticidal activity towards three commercially important insect species. Each gene was expressed individually and in combinations in Escherichia col

Molecular Characterization of Legionella Populations Present within Slow Sand Filters Used for Fungal Plant Pathogen Suppression in Horticultural Crops

Autor: T.R. Pettitt, Leo A. Calvo-Bado, J. Alun W. Morgan, Martin J. Sergeant, John M. Whipps

Publikováno v: Applied and Environmental Microbiology. 69:533-541

The total bacterial community of an experimental slow sand filter (SSF) was analyzed by denaturing gradient gel electrophoresis (DGGE) of partial 16S rRNA gene PCR products. One dominant band had sequence homology to Legionella species, indicating th

The role of bacterial motility in the survival and spread of Pseudomonas fluorescens in soil and in the attachment and colonisation of wheat roots

Autor: J. Alun W. Morgan, John R. Saunders, John M. Whipps, Gillian A. Turnbull

Publikováno v: FEMS Microbiology Ecology. 36:21-31

Motile and non-motile strains of Pseudomonas fluorescens SBW25 were constructed using different combinations of the lacZY, xylE and aph marker genes which allowed their detection and differentiation in soil, root and seed samples. The survival of mot
