Destructive actions of the microbes.
- causes diseases in human beings,live stocks and plants. For example, Meningitis,which is an inflammation of the protective covering of the brain. Other than that, they also play a part in the destruction of food by causing decomposition hence contributing to food deprivation.

Beneficial actions of some microbes.
-helps in the sewage treatment and also they are found in human’s gastrointestinal tract where it helps in maintaining a good environment for digestion to take place. The microbes also help in ecological balance by causing decomposition of dead matter to conserve the environment. Other than that, microbes are widely used in the production of foods such as cultured drinks,yogurt, cheese, soy sauce and many more.

Nur Suhadah Binti Abdul Kahar(197461)

2018-09-17 15:15:01 UTC

A destructive action of microbes is that they caused diseases.These Disease-causing microbes are not just affecting human but also plants and animals.

In human they attack our immune system .Because they are very quick at adjusting to new environment making it becomes so hard to get rid of them,in other words,they quickly become resistant to the 🤬 that were once killed them.They can also contribute to chronic diseases such as:
-Acquired Immunodeficiency Syndrome(🤬)
-Some form of cancer

A beneficial action of microbes is that whether we believe it or not they do protect our body.

Example:
- Bacillus subtilis. It can be found on the skin, and it makes bacitracin, a poison that helps it fight off other microbes.
- H. pylori helps protect against asthma, allergies and even cancer.

SUFIA NASIR (199045)

2018-09-17 15:16:16 UTC

DESTRUCTIVE
1. Eutrophication
The main effect that would happen is algal blooms where the stream, lake or ocean is covered with algae. This blocks sunlight from reaching the water this it prevents aquatic plant from photosynthesizing.

2. Acquired Immunodeficiency Syndrome (🤬)
It is caused by a virus named HIV (Human immunodeficiency Virus). It takes over cells vital to the immune respond which is known as CD4 + lymphocytes. This causes the cell to interfere with body’s ability to fight off infections, cancers and other disease.

3. Food Spoilage
This occurs as the food is exposed to air and surroundings. It is the change of look, consistency, flavor and odor of the food which is caused by bacteria, moulds and yeast. For example, lactobacillus causes the formation of lactic acid while proteus causes the formation of gas.

BENEFITS

1. Genetic Engineering
Genetic Engineering is an artificial recombination of DNA from two organisms. Bacteria can be genetic engineering to produce useful human proteins such as insulin. This could happen by inserting human insulin gene into a bacteria plasmid to gain the ability to produce insulin.

2. Decomposition
This is a natural process that causes large organic materials to be broken down into simpler ones which usually involves bacteria and fungus. Without the help of microorganism to undergo decomposition, the whole world would likely to end up with overcoming piles of dead biomass. Other than that, decomposition helps to recycles back nutrients to the soil.

3.Bioremediation

Bioremediation is the biodegradation of pollutants by microorganisms. It involves solving and removing dangers of many pollutants through biodegradation from environment. Microorganisms really help to restore original natural surroundings and prevent further pollution

2. Euthrophication caused by the cyanobacterial bloom within pond/lake.

Benefits :
1. Food production
-Microbes are used in fermentation such as alcohol, yogurt and cheese.
2. Microorganisms decompose organic waste to obtain nutrients. Thus, the process releases chemicals such as carbon,nitrogen and phosphorus. These chemicals will be used again in other chemical form such as nitrate into nitrite.

3. Animal
-Microbes help in digestion in animals when breaking down the cellulose cell wall of a plant. For example, cattle eats grass. The grass was digested by microbes.

The benefits of microbes activity :
1. In technology .
- Certain fungi have been theorized to have anti-cancer properties, and the CRISPR Cas9 gene found in certain types of bacteria is currently being used as a gene-editing tool.
- Viruses have the potential to act as the future of nanotechnology, and bacteria are currently being tested as the core component of self-repairing concrete that could revolutionize infrastructure and the way we build buildings.
2 . Medical benefits
- Bacteria and viruses are the key components of the vaccines that prevent the spread of once-deadly diseases like smallpox.
- microorganisms allow us to artificially grow helpful substances such as insulin and human growth hormones, and reprogrammed viruses are frequently used as drug-delivery mechanisms.
3. In our body
- Microorganisms known as gut flora which help us digest food and regulate the production of vitamins and nutrients which are essential to keeping our bodies strong and healthy.
- Bacteria are the first line of defense that defense human body against infection. The bacteria in our bodies produce natural antibiotics to repel harmful microorganisms, and if a foreign virus does infect us, many people are host to a beneficial virus that slows the rate of viral spread in the body.
4. In food
- They are used to increase the fertility of the soil and increase crop yields.
- They are necessary when making products like bread, beer and cheese and when growing coffee.
- Foods with probiotic properties, such as yogurt and certain types of chocolate, deliver helpful microorganisms to our digestive systems.

The destruction caused by microbes activity :
1. Food spoilage
- food spoilage is a metabolic process that couse the food to be undesirable and unacceptable for human consumption.
- In case of mp0oulds spoilage, a furry growth covers the food and it becomes soft and often smells bad.
- Bacterial contamination is more dangerous because usually the food does not look bad and appears normal even though it is severely infected .

2. Pathogens

1) Food: Production of many foods is possible with the help of microorganism. For example foods like bread, beer and cheese are produced with the help of yeast.

2] Medicine: It is very difficult to decode the human genome if any disorders occur in it as humans are the eukaryotic organisms. Microorganisms have made it possible to make such medicines which when enter the body, target the defected genes and make healthy changes in them and they become functional again.

3] Killing insect pests: The bacterium Bacillus thuringiensis (also known as Bt) produces a toxin that is specific to certain types of insects, many of which are pests encountered by gardeners and farmers. The toxin is so effective at killing the target insect that for years it has been used as an insecticide.

4] Treating sewage: Microorganisms are an important part of wastewater treatment during a few different steps of the process. After the sewage has been physically filtered to remove solid waste, microbes break down the insoluble organic matter during secondary treatment.

DESTRUCTIVE:
1. Pathogenic microbes cause diseases.
2. Food spoilage.

BENEFITS:
1. Microbes degrade dead plants and animals.
2. Decompose organic matter in sewage
3. Bioremediation processes use bacteria to clean up toxins waste.
4. Bacteria that cause diseases in insects are being used as biological controls of insect pests.
5. Produce important substances such as proteins, vaccines and enzymes by using recombinant DNA
6. Genetically modified bacteria are used in agriculture to protect plants from frost and insects and to improve the shelf life of produce.

Destructive :
1) Pathogens may cause cancer.
- Human papillomavirus (HPV); a group of more than 150 related viruses and can infect both men and women. HPV may cause penile HPV cancer in men and vaginal cancer in women. The viruses may also cause mouth or throat, and diseases when infected with HPV.

2) Microbes will make food go bad. Without heating or pasteurizing foods, microbes will grow on it and reproduce, sometimes secreting harmful substances for humans. For example, molds that grow on bread will release mycotoxin under certain conditions which is harmful for humans.

Benefits :

1) In cheese-making, Lactic Acid Bacteria plays an essential role as they converts lactose into lactic acid. This lowers the cheese pH, making it hard for many spoilage microbes to grow.

Propionic Acid Bacteria digests acetic acid and converts it into a sharp,sweaty-smelling propionic acid and carbon dioxide, CO2. CO2 creates the holes we see on the cheese surface.

2) Bacteria strain Lactobacillus in the Yakult yogurt drink are another example of beneficial role of microbes. They are good bacteria, usually found in human intestine and helps to prevent digestive disorders such as diarrhea and constipation. They also help build immunity and reduce the risk of infections.

A destructive action of a microbe is that pathogens could cause destruction such as:

1) Can cause disease like TB (Tuberculosis) cause by Mycobacterium tuberculosis.

2) Food spoilage such as souring of milk, rotting of vegetables and meat are caused by many saprotrophic bacteria.

3) Reduction of soil fertility such as denitrifying bacteria like Thiobacillus denitrificans, Micrococcus denitrificans, Pseudomonas aeroginosa convert soil nitrates and ammonia into free nitrogen and thus reduce the soil fertility.

The beneficial action of microbes such as:

1) Decomposition of organic waste such as disposal of sewage and agro-wastes. Bacteria decompose organic wastes of wage and agriculture into humus which can improve soil fertility.

2) Production of fermented goods in food industry such as in production of yogurt, cheese, beer and bread.

3) Production of energy. Microorganisms are used in fermentation to produce ethanol and in biogas reactors to produce methane. Scientists are researching the use of algae to produce liquid fuels and bacteria to convert various forms of agricultural and urban waste into usable fuels.
