Bacteria are everywhere we go, touch, eat and also can found inside of us. Bacteria belongs to the Domain bacteria therefore they considered some of the simplest organism and fall under the prokaryotic heading. Since these bacteria are prokaryotic they do not have a true nuclei and other membrane bound organelles. Furthermore, these bacteria are either single cell or live in colonies as independently functioning organisms. Majority of Bacteria is a crucial part of the planet as it’s found in all habitats supporting life and plays a role in decomposition and nutrient cycling. Not only do bacteria play an important role on the land but it also helps the aquatic environments for instance freshwater lakes, streams, river, swimming pools, oceans and the moist soil habitats. The bacteria that help the aquatic environments are called the cyanobacteria. The responsibilities of the cyanobacteria are to release a great amount of oxygen and are the food for various small organisms. Even though cyanobacteria are beneficial to the aquatic environments, some specific types can cause “algal blooms” which can be harmful to habitant of the affected environment.
Bacteria are good for the organisms and the environment but they also can be harmful. The harmful bacteria’s can cause certain diseases in both humans and animals. Ever since the discovery of diseases that are caused by bacteria, scientist continuing to develop methods to control the harmful bacteria. Some of the physical methods which help control the bacteria include heat, filtration, low temperatures, desiccation, osmotic pressure and radiation. Another process is using chemical agents which destroy or limit of bacteria. The chemical agents do not have the same effect on bacteria due to that some bacteria are gram negative. The gram negative bacteria have an extra lipid membrane surrounding which causes the impenetrable cell wall to many compounds. Since the gram positive is different in cell structure from gram...
