The effectiveness of 13 N-acetylneuraminic acid derivatives as potential inducers of Arthrobacter sialophilus neuraminidase were examined. N-Acetylneuraminic acid nitrogen and thioglycosides were not inducers, whereas 2,3-dehydro-N-acetylneuraminic acid, a transition state analog for neuraminidases, was the most effective inductive ligand. The C-4 hydroxyl function of N-acetylneuraminic acid wa...
Many Proteobacteria produce acyl-homoserine lactones (acyl-HSLs) and employ them as dedicated cell-to-cell signals in a process known as quorum sensing. Previously, Variovorax paradoxus VAI-C was shown to utilize diverse acyl-HSLs as sole sources of energy and nitrogen. We describe here the properties of a second isolate, Arthrobacter strain VAI-A, obtained from the same enrichment culture that...
Aerobic heterotrophs were isolated from subsurface soil samples obtained from the U.S. Department of Energy's (DOE) Field Research Center (FRC) located at Oak Ridge, Tenn. The FRC represents a unique, extreme environment consisting of highly acidic soils with co-occurring heavy metals, radionuclides, and high nitrate concentrations. Four hundred isolates obtained from contaminated soil were ass...
Renibacterium salmoninarum is the causative agent of bacterial kidney disease and a significant threat to healthy and sustainable production of salmonid fish worldwide. This pathogen is difficult to culture in vitro, genetic manipulation is challenging, and current therapies and preventative strategies are only marginally effective in preventing disease. The complete genome of R. salmoninarum A...
There are many reports of glycogen accumulation in various species of bacteria (58). However, the enzymatic synthesis of glycogen in bacteria has received little attention. Madsen has reported the presence of a UDP-glucose:glycogen transferase in Agrobacterium tumefaciens (A6) (9). Recently the occurrence of an ADP-glucose : glycogen transglucosylase in cell-free extracts of Arthrobacter was re...
