  2. Generation time - Wikipedia

    en.wikipedia.org/wiki/Generation_time

    One may then define the generation time as the time it takes for the population to increase by a factor of . For example, in microbiology , a population of cells undergoing exponential growth by mitosis replaces each cell by two daughter cells, so that R 0 = 2 {\displaystyle \textstyle R_{0}=2} and T {\displaystyle T} is the population doubling ...

  3. Bacterial growth - Wikipedia

    en.wikipedia.org/wiki/Bacterial_growth

    In comparison to batch culture, bacteria are maintained in exponential growth phase, and the growth rate of the bacteria is known. Related devices include turbidostats and auxostats . When Escherichia coli is growing very slowly with a doubling time of 16 hours in a chemostat most cells have a single chromosome.

    The 12 E. coli LTEE populations on June 25, 2008. [1]The E. coli long-term evolution experiment (LTEE) is an ongoing study in experimental evolution begun by Richard Lenski at the University of California, Irvine, carried on by Lenski and colleagues at Michigan State University, [2] and currently overseen by Jeffrey Barrick at the University of Texas at Austin. [3]

  5. Evolution of bacteria - Wikipedia

    en.wikipedia.org/wiki/Evolution_of_bacteria

    The evolution of bacteria has progressed over billions of years since the Precambrian time with their first major divergence from the archaeal/eukaryotic lineage roughly 3.2-3.5 billion years ago. [1] [2] This was discovered through gene sequencing of bacterial nucleoids to reconstruct their phylogeny.

  6. Subculture (biology) - Wikipedia

    en.wikipedia.org/wiki/Subculture_(biology)

    Subculturing can also be used for growth curve calculations (ex. generation time) [2] and obtaining log-phase microorganisms for experiments (ex. Bacterial transformation). [3] Typically, subculture is from a culture of a certain volume into fresh growth medium of equal volume, this allows long-term maintenance of the cell line.

    Its small stature and short generation time facilitates rapid genetic studies, [11] and many phenotypic and biochemical mutants have been mapped. [11] Arabidopsis was the first plant to have its genome sequenced. [11] Its genome sequence, along with a wide range of information concerning Arabidopsis, is maintained by the TAIR database. [11]

  8. Bacteria - Wikipedia

    en.wikipedia.org/wiki/Bacteria

    The rate at which cells grow during this phase is known as the growth rate (k), and the time it takes the cells to double is known as the generation time (g). During log phase, nutrients are metabolised at maximum speed until one of the nutrients is depleted and starts limiting growth.

  9. Bacterial genome - Wikipedia

    en.wikipedia.org/wiki/Bacterial_genome

    The data predicted that bacteria exhibiting a one-day generation time lose as many as 1,000 kbp in as few as 50,000 years (a relatively short evolutionary time period). Furthermore, after deleting genes essential to the methyl-directed DNA mismatch repair (MMR) system, it was shown that bacterial genome size reduction increased in rate by as ...
