The research is about the effect of Lactobacillus casei the potability and clearness of different types of water samples fromdifferent water sources in a typical community" The species of bacteria4Lactobacillus casei 5 is used for the study6 since it is common and is usas a pro$biotic in commercial products such as 3a7ult"

The bacteria will then be placed in different water samplesto see what will be the effect of the bacteria on that 7ind of water sample"
