The patent, issued to the University of Florida, covers a bacterial process to make ethanol, a type of alcohol that can be used in place of gasoline.

Typically in these types of events the sludge will have a profuse odor, due to lack of active bacterial processes.

Some nitrate is converted via an anaerobic bacterial process to free nitrogen, but this process is very difficult to maintain.

A bacterial process can reduce PCB's in rivers and lakes by more than 70 percent in four to eight weeks, scientists say.

Oxygen supplied to the roots via the reed stems encourages this bacterial process.

Anaerobic digestion is a bacterial process that is carried out in the absence of oxygen.

Aerobic digestion is a bacterial process occurring in the presence of oxygen.

Several weeks of soaking makes bast fibers easily separable due to bacterial and fermentative processes known as retting.

Dam plays several key roles in bacterial processes, including mismatch repair, the timing of DNA replication, and gene expression.
