Properties of some bacteriocins produced by Rhizobium trifolii

, : Properties of some bacteriocins produced by Rhizobium trifolii. Journal of General Microbiology 91(2): 403-413

Bacteriocins produced by six strains of Rhizobium trifolii were found to be of the relatively low molecular weight, non-phage type. The molecular weights ranged from approximately 1-8 X 105 to 2-0 X 105. All were of protein composition, as indicated by buoyant density (1-32 to 1-34 g/cm3) in CsC1 and by sensitivity to proteolytic enzymes. They were resistant to RNAase but sensitive to DNAase. The six bacteriocins could further be separated into two subgroups on the basis of sensitivity to extremes of pH, binding to filter membranes, activity spectrum on sensitive strains of R. trifolii, and possibly mode of action on sensitive bacteria. Bacteriocin production occurred spontaneously during the early-to mid-exponential phase of bacterial growth in broth culture.

Lipoxins (LX) are bioactive eicosanoids that carry a tetraene structure and serve as regulators of inflammation, in part by inhibiting neutrophil migration and adhesion. Lipoxin A-4 is rapidly regulated by conversion to inactive LX metabolites via...
