    The ability of bacteria to infect live animals or plants. Even if manipulated bacteria are shown in vitro to be able to infect host cells, their ability to sustain an infection in a live organism cannot be taken for granted. The expression levels of other genes. This can be assayed in several ways, notably northern blot and RT-PCR.

  5. Run-and-tumble motion - Wikipedia

    en.wikipedia.org/wiki/Run-and-tumble_motion

    Run-and-tumble motion is a movement pattern exhibited by certain bacteria and other microscopic agents. It consists of an alternating sequence of "runs" and "tumbles": during a run, the agent propels itself in a fixed (or slowly varying) direction, and during a tumble, it remains stationary while it reorients itself in preparation for the next run.

  6. Iron-oxidizing bacteria - Wikipedia

    en.wikipedia.org/wiki/Iron-oxidizing_bacteria

    The anoxygenic phototrophic iron oxidation was the first anaerobic metabolism to be described within the iron anaerobic oxidation metabolism. The photoferrotrophic bacteria use Fe 2+ as electron donor and the energy from light to assimilate CO 2 into biomass through the Calvin Benson-Bassam cycle (or rTCA cycle) in a neutrophilic environment (pH 5.5-7.2), producing Fe 3+ oxides as a waste ...

  7. Bacterial secretion system - Wikipedia

    en.wikipedia.org/wiki/Bacterial_secretion_system

    The general secretion (Sec) involves secretion of unfolded proteins that first remain inside the cells. In Gram-negative bacteria, the secreted protein is sent to either the inner membrane or the periplasm. But in Gram-positive bacteria, the protein can stay in the cell or is mostly transported out of the bacteria using other secretion systems.

  8. 3-Hydroxypropionate bicycle - Wikipedia

    en.wikipedia.org/wiki/3-Hydroxypropionate_bicycle

    The 3-hydroxypropionate bicycle, also known as the 3-hydroxypropionate pathway, is a process that allows some bacteria to generate 3-hydroxypropionate using carbon dioxide. [2] It is divided into two parts or reactions.

  9. Bacterial motility - Wikipedia

    en.wikipedia.org/wiki/Bacterial_motility

    Bacteria such as E. coli are unable to choose the direction in which they swim, and are unable to swim in a straight line for more than a few seconds due to rotational diffusion; in other words, bacteria "forget" the direction in which they are going. By repeatedly evaluating their course, and adjusting if they are moving in the wrong direction ...
