The bromuconazol is a fungicide which is toxic for the environment. This present study was led with the aim of testing, in vitro, its biodegradation. The bromuconazol was thus used in the presence of a microbial consortium resulting from a treated soil. A biphasic system MBS / oil of silicone was used during all the period of acclimatization. The fermentation was followed by measure of the optical density, the determination of the dry weight, the emulsifying power as well as the hydrophobicity of the selected consortium. The results obtained after one year revealed a strong adaptation of this one to the bromuconazol. The use of the biphasic system allowed a better assimilation of the pesticide. The microbiological study allowed identifying a single bacterial strain capable of using the fungicide as unique source of carbon. It is about Aeromonas hydrophila. This strain shows a strong hydrophobicity as well as an emulsifying power lived in saw some pesticide
