Annoying as they may be, they are also suitable helpers just as the role of a wife in the husband's life. They may be one of the most attacked species on earth yet their population is more than all living things combine. Less than 1% of microbes are currently known yet they are good servants but bad masters. Little is known about the way they behave and go about their duties. It is not surprising because it is extremely difficult to fight something that you can't set your eyes on. Microbes just like the members of class Insecta can inhabit every type of environment. Some live at temperatures above 120°C and as low as, below -30°C.

In their life process, they work incredibly like two sharp edges of a sword. They are cut with both edges and are busy when it came to their work. The importance of microbes can not be underestimated in the life of humans. We explore them to use them to satisfy our needs. On the other hand, microbes can be harmful, deadly and catastrophic they can warp up a whole generation if not treated with care. The emanation to tuberculosis, H1N1, coronavirus and the like are evil handy-works of microbes. Scientists have discovered a lot of ways to control their devastating effects. The more they try, the more troublesome they become. Microbes tend to develop new strains to overcome any form of source threat.


Are they a group of organisms that can not be seen with the naked eye unless with the help of a powerful microscope? They can inhabit different habitats due to their ability to easily multiply, this makes them quickly adapt to conditions that they are not previously used to. Some can live in an environment with a temperature above 100°C and sometimes in areas with temperatures as low as below -30°C. Temperature is not a barrier to their survival to a certain extent. Even though they are destroyed at extremely high and low temperatures,  Aside from temperature they can survive in extreme pH and acidic conditions.


The use of Microorganisms are used for food production and medicinal purposes started from the ancient world. When our ancestors began bread and cheese production through unintentional fermentation by unknown microorganisms. Let us uncover some of this importance.

1) FERMENTATION: For ages now our great grandparents unknowingly uses microorganisms to ferment food products to produce alcoholic products. For example, bread is produced from the anaerobic fermentation of fresh dough to produce sugar and carbon dioxide. The carbon dioxide produce causes the dough to rise. Also, most bear and other alcoholic food products are produced from the same or similar processes.

2 BIOREMEDIATION: Biologically microorganisms are used to break down organic food products to their simplest form humus in the soil. This hummus is of great importance to agriculture. Recent discoveries show that Japanese scientist has discovered a type of microns that can degrade plastic was produced in a matter of weeks or month.

3. DIGESTION:  Have you asked yourself what importance are the worms in the digestion trust of ruminants?  They aids in digestion, they help break food products into their monomers. Also, some microbes live in the digestive system ruminants and some other organisms. They help break food products into their simplest form. For example, there are some microorganisms in the large inserting that help break down cellulose food products and also help in the absorption of vitamin K.

4. PRODUCTION OF MEDICINES: Microorganisms are used in the field of medical sciences and the pharmaceutical industry to produce important products like antibiotics and medicines. For example, penicillin is produced with the help of microbes. Microbes are used to produce a large range of enzymes, antibodies, and vaccines. Example microorganisms are you to produce insulin which helps to reduce blood sugar levels. They are used in gene therapy, a situation in which the DNA and RNA samples of some microbes are used to treat some diseases and genetic disorders.


Microbes, unlike thing on earth, has both good and bad sides. Let us dive into some of the negative effects of microorganisms.

1. MICROBES ARE CAUSATIVE ORGANISMS FOR SOME DISEASES.  Microorganisms are responsible for causing a wide range of diseases, notable among them are contagious, infectious, communicable and non-communicable diseases. The major groups of microbes are viruses, bacterial, fungi and protest. The organisms are responsible for causing a countless number of diseases. Some of these include chickenpox, gonorrhoea, cholera, HIV AIDS and syphilis are among the diseases and infections caused by microbes.                                        

2. MICROBES PRODUCED TOXINS. Some microorganisms do not directly cause infections, they produce certain chemicals called harmful toxins which are very hazardous to other organisms. This toxin has the potential of distorting the host tissues and cells over time. Bacteria are fun of demonstrating this property.

3. THEY CAUSE FOOD SPOILAGE.  in addition to causing numerous diseases they also aid in food spoilage. They interact with the surface area of food products, trying to feed on the nutrients in there thereby causing early fermentation and early spoilage                                    

4. THEY AID TGE SPREAD OF DISEASES. Aside from the above negative effects of microbes, they also aid in the spread of diseases that these organisms may or may not be the main causative agents. Due to their nature, they are easily transferred by air, water and any other agent. As a result, they carry disease to and fro from its source of origin.


Almost all viruses are poisonous, the word virus means poison. And viruses are of almost no benefit to man. They cause various diseases and infections that are difficult to manage due to their constant mutation to form new strains of the same virus. On the other hand, mast bacteria are of great importance to man, they are used in various fields of science to produce meaningful results. Medicine, pharmacy, biotechnology, agriculture are the fields that bacteria are commonly used. Besides, bacteria is also known for causing some disease, common among they are genital infection and urinary tract infections. Fungi are of great importance just us bacterial. They are used as food (mushroom) and for medicinal and herbal purposes. They can also be cause few other diseases. Even though microorganisms are tag harmful for one reason or the other they are also a very useful and productive resource in many fields of science. More so, since much is not known about them it means that they are probably more useful benefits of microbes but recourse we have little knowledge about them, we are yet to explore these potentials.
