La difficulté qu'il y a à distinguer les cellules bactériennes actives des cellules en dormance ou mortes est un problème important pour les microbiologistes des milieux aquatiques. L'INT (2- (p-iodophenyl)-3- (p-nitrophenyl)-5-phenyl tetrazolium chloride) incolore est réduit par la respiration cellulaire en INT-Formazan opaque. Les cellules bactériennes actives peuvent ainsi être distinguées, par examen au microscope, des cellules bactériennes mortes ou en dormance. Cette méthode appliquée dans le lac Léman et dans un bassin d'aquaculture de Côte d'Ivoire montre que la proportion des cellules bactériennes actives varie entre quelques pour cents et près de 100% selon le lieu, la saison, le niveau et l'heure de la journée. Dans tous les cas,...
