The discussion on the importance of bacteria in our everyday life According to Colorado (2005), Bacteria are microscopic single celled organisms that reproduce by binary fission e.g. one cell splitting into another. Bacteria are not simply potential parasites of humans, but are engaged in many of the process that affects our existence. In this easy focuses are mainly on the different types of bacteria, the evolutional history of bacteria, Characteristics of bacteria, the importance of bacteria and the impact they have on human lives.
They are different types of bacteria in the world and they are driven by a number of characteristic that describe them. According to synder L (1997), there are different types of bacteria such as, the cyanobacteria, proteobacteria, actinobacteriam, and acidobacteria. Proteobacteria are gram negative bacteria that include photoautotrophs, chemotrophs and heterotrophs. Some proteobacteria are anaerobic and others are aerobic. Cyanobacteria are phototrophs that generate O2. Plant chloroplasts likely evolved from cyanobacteria by the process of endosymbiosis. Bacteria are found everywhere in the soil, water, inside your body and on your skin. A number of factors influence the rate at which bacteria grow factors such as moisture, temperature and the bacteria PH. Campbell and Reece (2010)states that, bacteria can multiple very rapidly under favourable conditions forming colonies of millions of organisms within a space as small as a drop of water.
