METHOD AND DEVICE FOR DETECTING THE FORMATION AND DEVELOPMENT OF BIOFILMS IN A CULTURE MEDIUM

摘要

the present invention relates to a method for measuring theviscosity of the culture medium (4).microorganisms (5), characterized in that it comprises the steps ofin: (a) depositing at least one particle.magnetic or magnetisable or electrically charged, coated with at least onemagnetic or magnetisable layer (3) in theculture (4), (b) subjecting the culture (4) to an electric or magnetic fieldin order to make the electromagnetic or particle.(3) (c) detection of movement, the degree of freedom of motion of the particle.(3) in culture. the present invention appliesmore specifically to a process and apparatus for detecting the formation andthe development of biofilms in a culture ofmicroorganisms.
