The growth of bacteria is affected by water, oxygen, nutrients, temperature and the medium's acidity. Bacteria are single-celled organisms found in water, air and on solid surfaces. Bacterial growth refers to the bacteria increasing in numbers of cells, rather than size.

Subtracting a past population value from the present population value, and dividing this result by the past population value, yields the population-growth rate. Multiplying the population-growth rate by 100 yields the growth percentage.

To calculate percent sales growth over a period, subtract the previous sales figure from the current sales figure, divide the result by the previous sales figure, and then multiply this number by 100, explains Michael Marz for the Houston Chronicle. In order to obtain the most accurate growth percen

Calculate population growth rate by dividing the change in population by the initial population, multiplying it by 100, and then dividing it by the number of years over which that change took place. The number is expressed as a percentage.

Bacteria are among the most numerous organisms on earth, explains Microbe World. Bacteria exists virtually everywhere on earth. Bacteria can be found in the air, soil, water, on plants, on animals and even on the skin of human beings.

Examples of bacteria include Streptococcus, Staphylococcus, and Esherichia coli, commonly known as E. coli. All of these bacteria are pathogenic and cause infection in humans and animals. However, there are non-pathogenic bacteria as well.

Bacteria are simple organisms that are found in every type of environment, including on land, in the air, in water and on and inside plants and animals. A bacterium (or single bacteria) is a single-celled creature that can take many shapes and forms.

The basic equation for calculating population growth multiplies the population size by the per capita growth rate, which is calculated by subtracting the per capita death rate from the per capita birth rate. This simplistic calculation does not factor in the effects of migration or immigration on a

According to Investopedia, to calculate an annual growth rate, take the ending value and divide it by the beginning value. Place that amount to the power of one over the number of years of growth, and subtract one from that amount. This averages growth over a period of years.
