Aromatic hydrocarbons bacteria

A nnmber of factors may therefore be involved in the tolerance of bacteria to aromatic hydrocarbons, althongh greatest attention has hitherto been centered on Gram-negative organisms.

Both procaryotic and eukaryotic microorganisms have the enzymatic potential to oxidize aromatic hydrocarbons that range in size from a single ring (e.g., benzene, toluene and xylene) to polycyclic aromatics (PC As), such as naphthalane, anthracene, phenanthrene, benzo [a] pyrene and benz [a] anthracene (Table 4.4). However, the molecular mechanisms by which bacteria and higher microorganisms degrade aromatic compounds are fundamentally different.

One of the largest groups of strictly aerobic heterotrophic bacteria, the pseudomonads (Pseudomonas and related genera), are of interest to biochemists because of their ability to oxidize organic compounds, such as alkanes, aromatic hydrocarbons, and steroids, which are not attacked by most other bacteria. Often, the number of oxidative reactions used by any one species of bacteria is limited. For example, the acetic acid bacteria that live in wine and beer obtain all of their energy by oxidation of ethanol to acetic acid ...
