By identifying the species, we can use them to help protect our planet. It’s like having tiny helpers that clean up messes we make.
Methods Used for Identifying Bacteria

There are many ways to do species identification of bacteria. It’s like being a detective with different tools. One way is to look at the bacteria under a microscope. Scientists can see what shape they are. Some are round, and others are like rods. Another way is to see how they grow. Some bacteria grow in groups. Other bacteria grow alone. Scientists can also test what the bacteria eat. Some like sugar. Some like other things. All these clues help scientists figure out the species of bacteria. It’s like putting together a puzzle with many different pieces. Each piece of information helps.
