Isolation and characterization of an anaerobic chlorophenol-transforming bacterium

Isolation and Characterization of Novel Sulfate-Reducing Bacterium Capable of Anaerobic Degradation of p-Xylene

A novel strain of p-xylene-degrading sulfate reducer was isolated in pure culture. Strain PP31 was obtained from a p-xylene-degrading enrichment culture established from polluted marine sediment. Analyses of the 16S rRNA gene and two functional genes involved in sulfate respiration and anaerobic degradation of aromatic compounds revealed that the isolate was closely related to members of the ge...

Alkaline anaerobic respiration: isolation and characterization of a novel alkaliphilic and metal-reducing bacterium.

Iron-reducing enrichments were obtained from leachate ponds at the U.S. Borax Company in Boron, Calif. Based on partial small-subunit (SSU) rRNA gene sequences (approximately 500 nucleotides), six isolates shared 98.9% nucleotide identity. As a representative, the isolate QYMF was selected for further analysis. QYMF could be grown with Fe(III)-citrate, Fe(III)-EDTA, Co(III)-EDTA, or Cr(VI) as e...

Isolation and characterization of an acrylamide-degrading Antarctic bacterium.

The presence of acrylamide in the environment poses a threat due to its well known neurotoxic, carcinogenic and teratogenic properties. Human activities in various geographical areas are the main anthropogenic source of acrylamide pollution. In this work, an acrylamide-degrading bacterium was isolated from Antarctic soil. The physiological characteristics and optimum growth conditions of the ac...

Metal-Reducing Bacterium and Characterization of a Novel Alkaliphilic Alkaline Anaerobic Respiration: Isolation

Isolation and Characterization of a Bacteriophage Preying an Antifungal Bacterium

Several Bacillus species were isolated from rice field soils, and 16S rRNA gene sequence analysis showed that Bacillus cereus was the most abundant. A strain named BC1 showed antifungal activity against Rhizoctonia solani. Bacteriophages infecting strain BC1 were isolated from the same soil sample. The isolated phage PK16 had an icosahedral head of 100 ± 5 nm and tail of 200 ± 5 nm, indicating ...
