Two morphological types of cell appendages on a strongly adhesive bacterium, Acinetobacter sp. strain Tol 5.

Effect of cell appendages on the adhesion properties of a highly adhesive bacterium, Acinetobacter sp. Tol 5.

A toluene-degrading bacterium, Acinetobacter sp. Tol 5, shows noteworthy adhesiveness mediated by two types of cell appendages. In this study, we obtained a less-adhesive mutant, T1, which lost both types of appendages, and investigated how the cell appendages affect the adhesion properties of this useful bacterium for environmental technology. Wild-type cells attained irreversible adhesion to ...

AtaA, a New Member of the Trimeric Autotransporter Adhesins from Acinetobacter sp. Tol 5 Mediating High Adhesiveness to Various Abiotic Surfaces

Acinetobacter sp. Tol 5 exhibits an autoagglutinating nature and noteworthy adhesiveness to various abiotic surfaces from hydrophobic plastics to hydrophilic glass and stainless steel. Although previous studies have suggested that bacterionanofibers on Tol 5 cells are involved in the adhesive phenotype of Tol 5, the fiber that directly mediates Tol 5 adhesion has remained unknown. Here, we pres...

The thin pili of Acinetobacter sp. strain BD413 mediate adhesion to biotic and abiotic surfaces.

Two structurally different appendages, thin and thick pili, are found in members of the genus Acinetobacter. The presence of pilus structures correlates with different phenotypes, such as adherence to surfaces, a trait not only observed in pathogenic Acinetobacter species, as well as motility. However, their distinct individual roles were unknown. To characterize the role of different pili in t...

Biodegradation of Phenol by Newly Isolated Phenol-degrading Bacterium Ralstonia sp. Strain PH-S1

A newly phenol-degrading bacterium, identified as Ralstonia sp. strain PH-S1, was isolated from oil-contaminated soil in Khark Island. It was isolated by a multistep enrichment and screening technique on mineral medium (MM) containing 100 mg.l-1 of phenol as the sole source of carbon. The bacterium was able to degrade up to 1100 mg.l-1 of phenol but the cell growth decreased with higher concent...
