Using a portable real-time PCR assay to detect Salmonella in raw milk

Autor: J S, Van Kessel, J S, Karns, M L, Perdue

Publikováno v: Journal of food protection. 66(10)

The purpose of this study was to determine the efficacy of a portable real-time PCR system in detecting Salmonella spp. in raw milk. The 200 bulk milk samples chosen for this study constituted a subset of the samples for a larger study; this subset c

Metabolism of twelve herbicides by Streptomyces

Autor: D. R. Shelton, B. M. Pogell, J. S. Karns, S. Khader

Publikováno v: Biodegradation. 7(2)

Experiments were conducted to assess the ability of Streptomyces (strain PS1/5) to metabolize twelve herbicides representing several different classes including: acetanilides, triazines, ureas, uracils, and imidazoles. Incubations in aqueous culture

Cloning and analysis of s-triazine catabolic genes from Pseudomonas sp. strain NRRLB-12227

Autor: J S Karns, R W Eaton

Pseudomonas sp. strain NRRLB-12227 degrades the s-triazine melamine by a six-step pathway which allows it to use melamine and pathway intermediates as nitrogen sources. With the plasmid pLG221, mutants defective in five of the six steps of the pathwa

Cloning and comparison of the DNA encoding ammelide aminohydrolase and cyanuric acid amidohydrolase from three s-triazine-degrading bacterial strains

Autor: J S Karns, R W Eaton

DNA encoding the catabolism of the s-triazines ammelide and cyanuric acid was cloned from Pseudomonas sp. strain NRRLB-12228 and Klebsiella pneumoniae 99 with, as a probe, a 4.6-kb PstI fragment from a third strain, Pseudomonas sp. strain NRRLB-12227

Metabolism of carbofuran by a pure bacterial culture

Autor: J. S. Karns, Judd O. Nelson, Walter Mulbry, Philip C. Kearney

Publikováno v: Pesticide Biochemistry and Physiology. 25:211-217

A bacterium WM111, isolated by soil enrichment and identified as an Achromobacter species, was capable of rapidly utilizing the insecticide carbofuran (2,3-dihydro-2,2-dimethyl-7-benzofuranyl methylcarbamate) as a sole source of nitrogen. The doublin

Cloning of a carbofuran hydrolase gene from Achromobacter sp. strain WM111 and its expression in gram-negative bacteria

Autor: P H Tomasek, J S Karns

A 14-kilobase-pair (kbp) EcoRI DNA fragment that encodes an enzyme capable of rapid hydrolysis of N-methylcarbamate insecticides (carbofuran hydrolase) was cloned from carbofuran-degrading Achromobacter sp. strain WM111. When used to probe Southern b

Publikováno v: Genetic Control of Environmental Pollutants ISBN: 9781468447170

Maintaining the carbon, nitrogen, and sulfur balances in the environment is one of the main tasks of microorganisms in nature; microorganisms degrade most compounds so that their basic elements can be recycled. However, naturally occurring chlorinate
