The expression of pathways for the catabolism of aromatic compounds is energetically
expensive, and aromatic compounds are generally toxic even to bacteria that can use them …

Synergistic regulation of the expression of various genes in a catabolic pathway is crucial for
the degradation, survival, and adaptation of microorganisms in polluted environments …

This chapter discusses the aspects of bioremediation that are related to metabolism of
recalcitrant chemicals by bacteria, leaving out also detoxification and immobilization of metal …

Background The σ 54 factor controls unique promoters and interacts with a specialized
activator (enhancer binding proteins [EBP]) for transcription initiation. Although σ 54 is …

Effective gene trapping and screening requires sensory and regulatory compatibility of both
host and exogenous systems. The naturally competent bacterium Acinetobacter baylyi ADP1 …

Although many nitroaromatic compounds have been in nature for only a few decades,
bacteria have already evolved the ability to metabolize them. Both horizontal transfer of …

Organohalides are organic molecules formed biotically and abiotically, both naturally and
through industrial production. They are usually toxic and represent a health risk for living …

Acinetobacter calcoaceticus PHEA-2 utilizes phenol as its sole carbon and energy source
and has a multi-component phenol hydroxylase-encoding gene operon (mphKLMNOP) for …

Bacteria live in an ever-changing environment and must alter protein expression promptly to
adapt to these changes and survive. Specific response genes that are regulated by a subset …

Gene regulatory networks exhibit complex, hierarchical features such as global regulation
and network motifs. There is much debate about whether the evolutionary origins of such …
