#481195-30 - Bacteria Growth Check for water quality testing is ideal for spot checks when bacteria presence is suspected. If an area is suspect for bacteria, either dip a test strip into the sample, or, for surfaces, add deionized/distilled water and swab. Insert the test strip back into its package and leave undisturbed for 48 hours at room temperature. Fastidious growth of total micro-organisms is demonstrated by the development of growth colonies on the test strip pad. Match the pad to the closest pattern match to determine an approximate bacteria count. Once a determination has been made, a decision to investigate using more enhanced bacteria testing measures can be more easily made. Bacteria Growth Check is also ideal for classroom lessons and discussions.

Did you know?? A number of bacteria cause disease, these are called pathogenic bacteria. They are the subject of Medical Microbiology and the exhibit pathogens deals with them. A separate exhibit explains about bacteria and food safety. Fortunately our immunesystem knows how to deal with them. However not all bacteria are 'bad guys'. We need bacteria to stay alive, as is explained in our exhibit commensals. Bacteria are prokaryotes (single cells that do not contain a nucleus). It may seem weird to classify organisms according to such details, but having or not having a nucleus is not trivial at all. The division between prokaryotes and eukaryotes (all organisms with a nucleus inside their cells) is of extreme importance in biology, and is the result of a major evolutionary breakthrough. Visit our other exhibits if you want to know more about bacteria and evolution, or in what extreme environments bacteria can be found.
