Adhesins encoded by the gingipain genes of Porphyromonas gingivalis are responsible for co-aggregation with Prevotella intermedia

Article Abstract:

Research has been conducted on bacterial cell co-aggregation which is caused by adhesion of one bacterium to another one. Results demonstrate that this co-aggregation between bacterial species is caused by cloned DNA region encoding one of the adhesim domains within rgpA and kgp.

Naturally occurring bacteria similar to the methyl tert-butyl ether (MTBE)-degrading strain PM1 are present in MTBE-contaminated groundwater

Article Abstract:

Research has been conducted on methyl tert-butyl ether-contaminated groundwater. The authors report the discovery of bacterial strain discovered in this groundwater which is identical to the native strain PM1, degrading methyl tert-butyl ether, in its ribosomal 16S DNA sequence.
