Lysis of Gram-Negative Bacteria by Serum [PDF]
The antibacterial property of serum, first reported by Nuttall in 1888, has attracted many investigators and an extensive literature has accumulated. The sera of most mammals tested have been found to possess bactericidal activity, but a notable exception is the mouse, whose serum, apparently through lack of complement, is unable to kill any of a ...

Quorum-sensing in Gram-negative bacteria [PDF]
It has become increasingly and widely recognised that bacteria do not exist as solitary cells, but are colonial organisms that exploit elaborate systems of intercellular communication to facilitate their adaptation to changing environmental conditions.

Stationary phase in gram-negative bacteria [PDF]
Conditions that sustain constant bacterial growth are seldom found in nature. Oligotrophic environments and competition among microorganisms force bacteria to be able to adapt quickly to rough and changing situations. A particular lifestyle composed of continuous cycles of growth and starvation is commonly referred to as feast and famine. Bacteria have

On the essentiality of lipopolysaccharide to Gram-negative bacteria [PDF]
Lipopolysaccharide is a highly acylated saccharolipid located on the outer leaflet of the outer membrane of Gram-negative bacteria. Lipopolysaccharide is critical to maintaining the barrier function preventing the passive diffusion of hydrophobic solutes such as antibiotics and detergents into the cell.

Acquisition of siderophores in Gram-negative bacteria
The outer membrane of Gram-negative bacteria constitutes a permeability barrier that protects the cell from exterior hazards, but also complicates the uptake of nutrients. In the case of iron, the challenge is even greater, because of the scarcity of this indispensable element in the cell's surroundings.

Solvent tolerance in Gram-negative bacteria
Bacteria have been found in all niches explored on Earth, their ubiquity derives from their enormous metabolic diversity and their capacity to adapt to changes in the environment. Some bacterial strains are able to thrive in the presence of high concentrations of toxic organic chemicals, such as aromatic compounds, aliphatic alcohols and solvents.

Replication of plasmids in gram-negative bacteria [PDF]
Replication of plasmid deoxyribonucleic acid (DNA) is dependent on three stages: initiation, elongation, and termination. The first stage, initiation, depends on plasmid-encoded properties such as the replication origin and, in most cases, the replication initiation protein (Rep protein).

Anhydrobiotic Engineering of Gram-Negative Bacteria [PDF]
ABSTRACT Anhydrobiotic engineering aims to improve desiccation tolerance in living organisms by adopting the strategies of anhydrobiosis. This was achieved for Escherichia coli and Pseudomonas putida by osmotic induction of intracellular trehalose synthesis and by drying from ...

The oxidation of methanol in gram-negative bacteria [PDF]
This is a brief review of the structure and interaction of methanol dehydrogenase and its electron acceptor cytochrome cL, their regulation by modifier protein, and the synthesis and assembly of the ‘methanol oxidase’ system.
