Definitions
- the present invention relates to a method for demonstrating the presence or absence of a particular microorganism strain in a culture medium.
- microorganism detection is very important especially in the food industry, the level of water control or medicine, knowing that these microorganisms may not only prove to be pathogenic, but also consist of agents setting obviously some types contamination.
- the coloring is often indicative of an enzymatic activity linked to the microorganism considered, and the result of this activity can result in a modification of the pH of the medium, highlighted by a colored indicator.
- Chromophores or fluorophores are compounds generally obtained by enzymatic hydrolysis of corresponding chromogenic or fluorogenic compounds, present in the culture medium.
- Fluorophores emit characteristic radiation by fluorescence.
- the chromophoric compounds are characterized by a color of a dominant wavelength.
- chromophoric compounds it will be noted in particular the derivatives of indoxyl, of hydroquinoline or also the naphthoic derivatives, or the derivatives of naphthyl and of phenyl.
- derived color any color whose dominant wavelength differs from the dominant wavelength of the chromophores released by the chromogens present in the culture medium taken alone in a standard medium.
- standard medium any usual identification medium in which the carbohydrate has a simple carbon source function, at very low concentrations, or even zero, where it is considered that such concen ⁇ trations make it possible to avoid any inducing effect which would uncontrollably modify the behavior of the microorganisms and would induce errors in the identification of the microorganisms considered.
- the dominant wavelength of the chromophore may be calculated with reference to daylight, as defined by the CIE (International Energy Commission) as illuminating Des, using any standard method of measuring object color , in particular with a spectrocolorimeter.
- the present invention therefore relates to a method for demonstrating the presence or absence of a particular microorganism strain in a medium, characterized in that at least one chromogenic substrate is introduced into the culture medium.
- strain enzyme and at least one compound chosen from a high concentration carbohydrate so to obtain, after hydrolysis of the chromogen, a color different from the basic color of the chromophore.
- the medium is advantageously a peptone-based medium.
- carbohydrate is understood to mean, according to the invention, all of the natural or non-natural sugars, in particular the oses, in particular pentoses or hexoses, preferably glucose.
- the high concentration of carbohydrate is of the order of 10 to 30 g 1 of medium.
- the present invention relates to a process as defined above, in which the culture medium comprises a high concentration of phosphate, preferably between 1 and 3 g / l.
- the chromogens are in particular substrates for the following enzymes: ⁇ -galactosidase, ⁇ -glucuronidase, ⁇ -glucosidase, ⁇ -glucosidase, ⁇ - galactosidase, phosphatase, N-acetyl- ⁇ - gluconidase, N-acetyl- ⁇ -galactosidase , ⁇ -mannosidase, sulfatase, esterase, lipase and peptidase.
- the medium advantageously comprises at least two chromogens, in particular chosen from compounds of the same chemical family, preferably from those which release by hydrolysis two different chromophores which can undergo a coupling reaction.
- coupling reaction any physicochemical interaction by which the resulting dominant wavelength is different from the dominant wavelength of the mixture of the two chromophores taken in isolation.
- the chromogens are from the family of indoxyls, in particular alkylated, halogenated or dihalogenated indoxyl derivatives.
- the preferred indoxylated chromophores are the indoxyl, bromo-indoxyl, chloro-indoxyl, dichloro-indoxyl, chloro-bromo-indoxyl, tri-chloro-indoxyl and methyl-indoxyl derivatives, in particular the following derivatives: 6- chloro-indoxyl, 5-bromo-indoxyl, 3-bromo-indoxyl, 4,6-dichloro- indoxyl, 6,7-dichloro-indoxyl, 5-bromo-4-chloro-indoxyl, 5-bromo-6-chloro-indoxyl or 4,6,7-trichloro-indoxyl.
- microorganism whose presence or absence is demonstrated by the process according to the invention, is meant yeasts, unicellular fungi or molds and bacteria.
- the method according to the invention is particularly suitable for demonstrating the presence or absence of yeasts of the genus Candida. in particular Candida albicans and Candida tropicalis.
- bacteria of the genus Streptococcus Klebsiella, Enterobacter. Escherichia. Citrobacter. Staphylococcus. Listeria. Clostridium or Proteus.
- Agar 15 Agar 15
- Culture media the following media were prepared for the implementation of the process according to the invention.
