  2. Bacterial growth - Wikipedia

    en.wikipedia.org/wiki/Bacterial_growth

    The cells do not reproduce in synchrony without explicit and continual prompting (as in experiments with stalked bacteria [9]) and their exponential phase growth is often not ever a constant rate, but instead a slowly decaying rate, a constant stochastic response to pressures both to reproduce and to go dormant in the face of declining nutrient ...

  3. Bacteria - Wikipedia

    en.wikipedia.org/wiki/Bacteria

    Bacteria grow to a fixed size and then reproduce through binary fission, a form of asexual reproduction. [114] Under optimal conditions, bacteria can grow and divide extremely rapidly, and some bacterial populations can double as quickly as every 17 minutes. [115] In cell division, two identical clone daughter cells are produced. Some bacteria ...

  4. Microbiological culture - Wikipedia

    en.wikipedia.org/wiki/Microbiological_culture

    Some types of bacteria can only grow in the presence of certain additives. This can also be used when creating engineered strains of bacteria that contain an antibiotic-resistance gene. When the selected antibiotic is added to the agar, only bacterial cells containing the gene insert conferring resistance will be able to grow.

  5. Biological exponential growth - Wikipedia

    en.wikipedia.org/wiki/Biological_exponential_growth

    Most commonly apparent in species that reproduce quickly and asexually, like bacteria, exponential growth is intuitive from the fact that each organism can divide and produce two copies of itself. Each descendent bacterium can itself divide, again doubling the population size (as displayed in the above graph). [ 2 ]

  6. Experts Say You Should Never Undercook This Type Of Meat - AOL

    The freshness of the meat and how quickly it is cooked play a key role. "If the meat was cut and ground immediately before cooking, that surface bacteria has had less time to multiply and increase ...

    Food should not stay in the temperature danger zone — between 40 and 140 degrees Fahrenheit — for more than two hours because that can cause bacteria to multiply quickly, increasing the risk ...

  8. Colony-forming unit - Wikipedia

    en.wikipedia.org/wiki/Colony-forming_unit

    In microbiology, a colony-forming unit (CFU, cfu or Cfu) is a unit which estimates the number of microbial cells (bacteria, fungi, viruses etc.) in a sample that are viable, able to multiply via binary fission under the controlled conditions. Counting with colony-forming units requires culturing the microbes and counts only viable cells, in ...

  9. Microorganism - Wikipedia

    en.wikipedia.org/wiki/Microorganism

    Microorganisms tend to have a relatively fast rate of evolution. Most microorganisms can reproduce rapidly, and bacteria are also able to freely exchange genes through conjugation , transformation and transduction , even between widely divergent species. [ 38 ]
