Specific Growth Rate - Specific Growth Rate Constant

Specific Growth Rate Constant

Specific growth rate constant is a way of measuring how fast the cells are dividing in a culture. It is defined on the basis of doubling rate, and mathematically it can be explained by the following formula:

k = 1/Log 2 x 1/t x (Log Nt - Log No)

it can be modified as:

k= 3.32 x 1/t x (Log Nt - Log No)

where k= growth rate constant

Nt = number of bacteria at a time t

No = number bacteria at start

t = time.

Famous quotes containing the words specific, growth, rate and/or constant:

    The more specific idea of evolution now reached is—a change from an indefinite, incoherent homogeneity to a definite, coherent heterogeneity, accompanying the dissipation of motion and integration of matter.
    Herbert Spencer (1820–1903)

    The risk for a woman who considers her helpless children her “job” is that the children’s growth toward self-sufficiency may be experienced as a refutation of the mother’s indispensability, and she may unconsciously sabotage their growth as a result.
    Letty Cottin Pogrebin (20th century)

    You are more than entitled not to know what the word ‘performative’ means. It is a new word and an ugly word, and perhaps it does not mean anything very much. But at any rate there is one thing in its favor, it is not a profound word.
    —J.L. (John Langshaw)

    The thirsty earth soaks up the rain,
    And drinks, and gapes for drink again.
    The plants suck in the earth, and are
    With constant drinking fresh and fair.
    Abraham Cowley (1618–1667)
