Isolation and identification of a morpholine-degrading bacterium

Isolation and identification of a morpholine-degrading bacterium.

A gram-positive, slowly growing rod effectively utilizing morpholine as the sole source of organic carbon, nitrogen, and energy was isolated from a mixed culture in a laboratory reactor. The strain was tentatively identified as Mycobacterium aurum. Its growth characteristics at 20 degrees C and pH 6.5 were as follows: maximum specific growth rate, 0.052 h-1; half-velocity constant, 1.3 mg/liter...

Isolation, identification, and characterization of a feather-degrading bacterium.

A feather-degrading culture was enriched with isolates from a poultry waste digestor and adapted to grow with feathers as its primary source of carbon, sulfur, and energy. Subsequently, a feather-hydrolytic, endospore-forming, motile, rod-shaped bacterium was isolated from the feather-degrading culture. The organism was Gram stain variable and catalase positive and demonstrated facultative grow...

Construction and Characterization of a Lux-Marked Phenanthrene Degrading Bacterium

Isolation and Characterization of Microcystin- Degrading Bacterium

The most commonly encountered cyanobacterial toxins in freshwater are microcystins. Microcystins are extremely stable and resistant to chemical hydrolysis or oxidation and can cause illness or death in animals and humans. In this study, a total of 15 bacterial strains were isolated and screened for microcystin degradative activity from Kaen Nakhon Lake, Khon Kaen Province, Thailand. Among these...

Isolation and characterization of a fluorene-degrading bacterium: identification of ring oxidation and ring fission products.

An Arthrobacter sp. strain, F101, able to use fluorene as the sole source of carbon and energy, was isolated from sludge from an oil refinery wastewater treatment plant. During growth in the presence of fluorene, four major metabolites were detected and isolated by thin-layer chromatography and high-performance liquid chromatography. 9-Fluorenol, 9H-fluoren-9-one, and 3,4-dihydrocoumarin were i...
