Acyl‐homoserine lactone acylase from Ralstonia strain XJ12B represents a novel and potent class of quorum‐quenching enzymes
N ‐acylhomoserine lactones (AHLs) are used as signal molecules by many quorum‐sensing Proteobacteria. Diverse plant and animal pathogens use AHLs to regulate infection and virulence functions. TheseExpand

Metabolism of acyl-homoserine lactone quorum-sensing signals by Variovorax paradoxus.
Acyl-homoserine lactones (acyl-HSLs) serve as dedicated cell-to-cell signaling molecules in many species of the class Proteobacteria. We have addressed the question of whether these compounds can beExpand

Physiological ecology of Methanobrevibacter cuticularis sp. nov. and Methanobrevibacter curvatus sp. nov., isolated from the hindgut of the termite Reticulitermes flavipes.
Two morphologically distinct, H2- and CO2-utilizing methanogens were isolated from gut homogenates of the subterranean termite, Reticulitermes-flavipes (Kollar) (Rhinotermitidae). Strain RFM-1 was aExpand

Identification of QuiP, the Product of Gene PA1032, as the Second Acyl-Homoserine Lactone Acylase of Pseudomonas aeruginosa PAO1
ABSTRACT The relevance of the acyl homoserine lactone (acyl-HSL) quorum signals N-3-oxododecanoyl-homoserine lactone (3OC12HSL) and N-butanoyl-homoserine lactone to the biology and virulence ofExpand

Utilization of Acyl-Homoserine Lactone Quorum Signals for Growth by a Soil Pseudomonad and Pseudomonas aeruginosa PAO1
ABSTRACT Acyl-homoserine lactones (AHLs) are employed by several Proteobacteria as quorum-sensing signals. Past studies have established that these compounds are subject to biochemical decay and canExpand

Nitrogen Fixation by Symbiotic and Free-Living Spirochetes
Spirochetes from termite hindguts and freshwater sediments possessed homologs of a nitrogenase gene (nifH) and exhibited nitrogenase activity, a previously unrecognized metabolic capability inExpand

Structural diversity of bacterial flagellar motors
The bacterial flagellum is one of nature's most amazing and well‐studied nanomachines. Its cell‐wall‐anchored motor uses chemical energy to rotate a microns‐long filament and propel the bacteriumExpand

Acetogenesis from H2 plus CO2 by spirochetes from termite guts.
Pure cultures of termite gut spirochetes were obtained and were shown to catalyze the synthesis of acetate from H2 plus CO2. The 16S ribosomal DNA sequences of two strains were 98 percent similar andExpand
