How do you calculate generation time?

How do you calculate generation time?

The rate of exponential growth of a bacterial culture is expressed as generation time, also the doubling time of the bacterial population. Generation time (G) is defined as the time (t) per generation (n = number of generations). Hence, G=t/n is the equation from which calculations of generation time (below) derive.

Is B subtilis gram negative?

In terms of popularity as a laboratory model organism, B. subtilis is often considered as the Gram-positive equivalent of Escherichia coli, an extensively studied Gram-negative bacterium.

Where is Bacillus subtilis most commonly found?

Bacillus subtilis, a low %G+C, Gram-positive, endospore-forming member of the bacterial phylum Firmicutes, is found predominately in the soil and in association with plants.

Is Bacillus subtilis good or bad?

Bacillus subtilis , as one of the three most common species of probiotic products in the United States [49], has been widely used as functional feed supplements, such as in a number of dairy and non-dairy fermented foods, for improving human health and well-being [50, 51, 52].

What is the optimum temperature for Bacillus subtilis?

around 34°C

Is Bacillus subtilis aerobic or anaerobic?

The Gram-positive soil bacterium Bacillus subtilis, generally regarded as an aerobe, grows under strict anaerobic conditions using nitrate as an electron acceptor and should be designated as a facultative anaerobe.

Is Bacillus anthracis aerobic or anaerobic?

Bacillus anthracis is an aerobic spore-forming bacterium that causes disease in humans and animals. The bacteria is found in two forms: cutaneous anthrax and inhalation anthrax.

What do anaerobic bacteria use instead of oxygen?

Anaerobic respiration is a type of respiration where oxygen is not used; instead, organic or inorganic molecules are used as final electron acceptors. Fermentation includes processes that use an organic molecule to regenerate NAD+ from NADH.
