Heterotrophic Plate counting is the Standard plate count Methods used widely to enumerated the range of genera bacteria number in water.<br>HPC bacteria are naturally present in all environments many species make contamination and as a reservoir for biofilm-forming pathogens in water and byproducts, From the data as showed in the table 3.<br>Which the standards or guidelines vary among countries for HPC bacteria in water around 100-500 CFU/ml But WHO determine the HPC bacteria level is normally no more than 100 CFU/ml in drinking water.<br>According to the study, the impact of storage time on the HPC bacteria growth in reusable bottles. Found that bacteria content costs that the specified standard and could be associated risk to consumer health.<br>****** ...
