The biosorption of lead by two Gram-ve bacteria, either non-capsulated (Citrobacter freundii ) or capsulated (Klebsiella pneumoniae) was characterised. Lead biosorption was found to be influenced by the pH of the solution, initial metal concentration, and amount of the dried powdered cells and ...

Figure 5a shows a heat map of the modA2ON status of the inoculum, and the bacteria isolated from both middle ears. Animals challenged with the predominantly modA2ON variant (green) remained ON, whereas those animals challenged with the predominantly modA2OFF variant (red) showed a consistent ...
Noncapsulated mutants of normally encapsulated bacteria in which the capsule is required for virulence are useful as vaccines for disease states caused by the normally encapsulated bacteria. In particular, noncapsulated mutants of A. pleuropneumoniae, Pasteurella haemolytica, and Pseudomonas aeruginosa, ...

coli, Acinetobacter calcoaceticus, and Erwinia stewartii strains are more resistant to desiccation than non-capsulated strains [34]. In addition, CPS can allow bacterial adherence to host cells, surfaces, and to each other, thereby facilitating biofilm formation and colonization [35]. Biofilm ...
