ABSTRACT
To set up a new method of detecting bacterial number in situ,NADH fluorescence method based on the fluorescent characteristic of NADH was used.When the concentration of NADH ranged from 10 nmol/L to 0.2 mmol/L,its concentration had a good line relationship to the fluorescence intensity(R2= 0.9905).Separating bacterial cells by centrifugation and extracting NADH with hot Tris-HCl buffer,the re-sult of bacterial count detected with NADH standard plot was 1?104 CFU/mL in an hour.In summary,NADH fluorescence method is rapid,sensitive,simple and reliable to detect total bacterial number.There-fore,the method can be widely applied in the field of food sanitation and safety,environment detection and so on.
