[Table: see text].This guidance document is intended to assist the applicant in preparation and presentation of an application, as foreseen Article 7.6 Regulation (EC) No 1831/2003, for authorisation additives use animal nutrition. It specifically covers characterisation microorganisms used feed or production organisms.
Like bacteria, fungi play an important role in the soil ecosystem. As only a small fraction of present can be cultured, conventional microbiological techniques yield limited information on composition and dynamics fungal communities soil. DNA-based methods do not depend culturability microorganisms, therefore they offer attractive alternative for study complex community structures. For this purpose, we designed various PCR primers that allow specific amplification 18S-ribosomal-DNA (rDNA)...

ABSTRACT We released genetically modified Pseudomonas putida WCS358r into the rhizospheres of wheat plants. The two derivatives, microorganism (GMM) 2 and GMM 8, carried phz biosynthetic gene locus strain P. fluorescens 2-79 constitutively produced antifungal compound phenazine-1-carboxylic acid (PCA). In springs 1997 1998 we sowed seeds treated with either 2, or (approximately 10 7 CFU per seed), measured numbers, composition, activities rhizosphere microbial populations. During both...
Colonization-defective, transposon-induced mutants of the efficient root colonizer Pseudomonas fluorescens WCS365 were identified with a gnotobiotic system. Most impaired in known colonization traits, i.e., prototrophy for amino acids, motility, and synthesis O-antigen LPS (lipopolysaccharide). Mutants lacking both competitive growth whereas one mutant (PCL1205) shorter chain was defective only ability, suggesting role intact colonization. Eight that not above-mentioned traits colonized...
We determined whether isolates of the take-all pathogen Gaeumannomyces graminis var. tritici become less sensitive to 2,4-diacetylphloroglucinol (2,4-DAPG) during wheat monoculture as a result exposure antibiotic over multiple growing seasons. Isolates G. were baited from roots native grasses collected noncropped fields and with different cropping histories near Lind, Ritzville, Pullman, Almota, WA. characterized by using morphological traits, variety-specific polymerase chain reaction...
