The invention relates to a method for detecting the Gram type and the fermenting character of a bacterial strain, said method comprising: illuminating, in the wavelength range of 390 nm to 900 nm, at least one bacterium from said strain which has a natural electromagnetic response within said range; acquiring, within said range, a light intensity reflected by, or transmitted through, said illuminated bacterium; and determining the Gram type and the fermenting character of the bacterial strain according to the light intensity acquired within said range.

Method and system for identifying the gram type of a bacterium

Method for characterising a microorganism, comprising: —illuminating, in the wavelength range of 390 nm-900 nm, the microorganism having a natural electromagnetic response in said range; —acquiring, in said range, a light intensity reflected by said (or transmitted through said) illuminated microorganism; and —determining the microorganism as being a yeast or a bacterial strain according to the light intensity acquired in said range.
