Discuss the role of microbiology in ensuring food supplies and food safety.
Microbiology has had a big part in food safety and food supply. Microbiology has educated us on how different ways to preserve our food. Microbiology has helped immensely with food supply, by making efforts to keep harmful organisms from our food. Teaching us the importance of not only nourishing our bodies but making sure its safe and abundant is what microbiology has don for us.
Microbiology has helped preserve our food through different processes. By making sure our food doesn’t go bad very quickly that can also manage waste. More than 25% of food supply is wasted, however people die of hunger everyday. So by using microbial processes we can make
Many relate the existence of cyanobacteria to be the reason for life on earth. Cyanobacteria are aquatic and photosynthetic. They live in the water and can find their own food. Since they are bacteria they have one cell and are really small, but grow in large colonies. They are distinctive because they have one of the oldest fossils being over 3.5 billion years old.
Cyanobacterium have an immense importance because they shaped the course of evolution by being an important maker of nitrogen fertilizer which make beans and rice. The planets oxygen atmosphere is because of cyanobacteria. Since before time we didn’t have much chemistry in the atmosphere that was made for life.
Another importance would be the origin of plants. The chloroplast plants eat is a cyanobacterium that lives in plants. They are often call blue-green algae for their prescence in water and their color.
I actually learned of this microbe at work. I was so interested even though I don’t believe in the textbook definition of evolution. One of my coworkers said that he believed Cyanobacterium was GOD. As I became alert from his answer, I began to research it. Although, I still don’t believe the bacteria is GOD it still certainly deserves
Many people feel that biology has become more advanced than physics. Biology has in fact become the new focus of the future as we tend to use it a lot in our daily lives. The study of Biotechnology is known as the branch of molecular biology that studies the use of microorganisms to perform specific industrial processes. This study shows that our lives can be transformed.
...standing the nature of relationship between the residing microbes inside human cells and about their function is very important to put an end to this war and to live in peace with the natural organisms that are benefitting human body and their survival has become our primary importance.
Photosynthetic organisms are those who convert the sun’s energy through a process called photosynthesis. They are also referred to as autotrophs. These organisms include plants, algae, and some bacteria. These organisms take in energy from the sun and water. They then complete the steps of photosynthesis and produce oxygen and glucose. All living organisms on earth require oxygen to survive. Plants provide a continuous supply of oxygen for these organisms. Without plants, there would be less oxygen molecules present in the atmosphere, creating a potential threat to organisms that require oxygen.
Biotechnology has helped make food at a quicker and an even more affordable rate for the consumer of the food. Animals and crops have been bred for centuries and the disease resistance has been improved.
All eukaryotic plant cells that have coloured plastids contain their photosynthetic pigments in these membrane bound units [3]. In land plants, the facilitators of photosynthesis are the chloroplasts.
To many, prokaryotes may seem as uninteresting, insignificant organisms, but to biologists, prokaryotes have the greatest success story in the history of life.
Biotechnology is a growth field that consists of the use of biological systems or living organisms in which technology is developed and applied1. Take a look at IBB in figure 1 below it shows an increasing upward trend in the past 5 years showing the fast expansion and growth of the bio sector. One of the significance and importance of biotechnology is that it covers almost every field. The application of biotechnology can be used for industrial, agricultural and medical purposes. The study of microorganisms and particles can be beneficial to mankind. With a clear understanding of internal body composition and molecular behaviour, vaccines and medications can be produced to treat diseases and conditions. Fruits and vegetables can be modified to grow faster, taste better, resist different temperatures, repels insects, etc2. Although biotechnology has the potential to affect modern society and have a positive impact on the environment, the misuse of such technology can lead to devastating consequences and side effects. The creation of bioweapons, food toxicity, errors in products and many ethical issues are also to be considered with the development of such technology. However, the upside and potential breakthrough in this technology could feed the hungry, reduce environmental or human footprint, develop cleaner and more efficient energy sources, etc. On top of this, the emerging applications in the biotech sector is creating plenty of opportunities for businesses that offer biotech related services for other organisations to make use of3. Examples of these applications and subjects include combinatorial chemistry, bioinformatics, biochips, proteomics and high-throughput screening. However on of the most looked at, compelling and c...
Microbial decomposition releases nutrients into the environment that are needed by other organisms. Microbes are also involved in the cycling of many other important compounds in — and between — ecosystems, including oxygen, carbon and nitrogen. Many microbes use the energy of sunlight to convert carbon dioxide to oxygen, which we need to breathe. As they do this, they create new organic material — themselves — which are then eaten by other organisms. In this way, the cycling of nutrients and energy
Bacterial cells, like plant cells, are surrounded by a cell wall. However, bacterial cell walls are made up of polysaccharide chains linked to amino acids, while plant cell walls are made up of cellulose, which contains no amino acids. Many bacteria secrete a slimy capsule around the outside of the cell wall. The capsule provides additional protection for the cell. Many of the bacteria that cause diseases in animals are surrounded by a capsule. The capsule prevents the white blood cells and antibodies from destroying the invading bacterium. Inside the capsule and the cell wall is the cell membrane. In aerobic bacteria, the reactions of cellular respiration take place on fingerlike infoldings of the cell membrane. Ribosomes are scattered throughout the cytoplasm, and the DNA is generally found in the center of the cell. Many bacilli and spirilla have flagella, which are used for locomotion in water. A few types of bacteria that lack flagella move by gliding on a surface. However, the mechanism of this gliding motion is unknown. Most bacteria are aerobic, they require free oxygen to carry on cellular respiration. Some bacteria, called facultatibe anaerobes can live in either the presence or absence of free oxygen. They obtain energy either by aerobic respiration when oxygen is present or by fermentation when oxygen is absent. Still other bacteria cannot live in the presence of oxygen. These are called obligate anaerobes. Such bacteria obtain energy only fermentation. Through fermentation, different groups of bacteria produce a wide variety of organic compounds. Besides ethyl alcohol and lactic acid, bacterial fermentation can produce acetic acid, acetone, butyl alcohol, glycol, butyric acid, propionic acid, and methane, the main component of natural gas. Most bacteria are heterotrophic bacteria are either saprophytes or parasites. Saprophytes feed on the remains of dead plants and animals, and ordinarily do not cause disease. They release digestive enzymes onto the organic matter. The enzymes breakdown the large food molecules into smaller molecules, which are absorbed by the bacterial cells. Parasites live on or in living organisms, and may cause disease. A few types of bacteria are Autotrophic, they can synthesize the organic nutrients they require from inorganic substances. Autotrophic bacteria are either photosynthetic or Chemosynthetic. The photosynthetic bacteria contain chlorophyll that are different from the plant chlorophyll. In bacterial photosynthesis, hydrogen is obtained by the splitting of compounds other than water.
Photosynthetic pigments are essential for life because they allow photosynthesis to occur by capturing sunlight which is then used alongside carbon dioxide and water to form organic compounds such as glucose and oxygen. The pigments allow the conversion of light energy to chemical energy which other organisms can benefit from. Oxygen is utilised by other organisms in aerobic respiration. The different pigments present in the chloroplasts allow a wide variety of wavelengths of light to be absorbed for efficient photosynthesis and provide colours to the plant to attract pollinators.
The energy extracted today by the burning of coal and petroleum products represents sunlight energy captured and stored by photosynthesis almost 200 million years ago. A third very interesting group of bacteria synthesize sugars, not by using sunlight’s energy, but by extracting energy from inorganic chemical compounds; In a (d) deep sea vent, chemoautotrophs, such as these (e) thermophilic bacteria, capture energy from inorganic compounds to produce organic compounds.

Gene Technology and Biotechnology are a boon to this world. Putting microorganisms to use in the formation of insu...
In this assignment I am going to explain the 5 different social benefits of micro-organisms. The areas I am going to talk about are as follows;
The myriad mysteries of science can be unraveled by the emerging technologies including Biotechnology. Science has always been my interest and forte thus, the choice of Biotechnology as my academic option was the ideal decision. I had prepared for the highly competitive entrance exam AIET to get admission into the integrated Masters Degree in Biotechnology and Bioinformatics at Dr. D.Y. Patil University and secured 87th all over India rank and was proud to gain admission to this venerated university. The academic curriculum has introduced me to amazing subjects like ‘Microbiology’, ‘Molecular Biology’, ‘Biochemistry’, ‘Genetics’ and ‘Industrial Biotechnology’. Although many seminal biological events have been explained in theory during the past century, the technology to harness their potential for benefiting humankind has only been possible during the past few decades. This is testament to the great improvements in biotechnologies and I am glad to be a part of this grand scientific experience.
Photosynthesis is a key contributor to all living things; photosynthesis provides the oxygen, food, and nutrients that help all living things stay healthy and alive. Photosynthesis converts solar energy into the chemical energy of a carbohydrate. Photosynthetic organisms, including land plants, algae, and cyanobacteria, which are called autotroph...
