this presentation show details regarding how the concept of agricultural microbiology came into existance and also the contribution of various scientists
This presentation is made for S.Y.Bsc. Students.
The presentation includes Drinking water microbiology. The presentation includes information about coliform, indicator organisms as well as purification methods of drinking water.
Evolution Of Bacteria
Bacteria have existed from very early in the history of life on Earth. Bacteria fossils discovered in rocks date from at least the Devonian Period (419.2 million to 358.9 million years ago), and there are convincing arguments that bacteria have been present since early Precambrian time, about 3.5 billion years ago. Bacteria were widespread on Earth at least since the latter part of the Paleoproterozoic, roughly 1.8 billion years ago, when oxygen appeared in the atmosphere as a result of the action of the cyanobacteria. Bacteria have thus had plenty of time to adapt to their environments and to have given rise to numerous descendant forms.
Industrial microbiology is a branch of applied microbiology in which microorganisms are used in industrial processes.
Example: In the production of high-value products such as drugs, chemicals, fuels and electricity.
Microbes are the mini chemical factory
Possess a broad variety of enzymes
High metabolic activity. So, it can grow and multiply rapidly
Possess a large surface area for the quick absorption of nutrients
Grow on inexpensive substrate

The heart of the fermentation or bioprocess technology is the Fermentor or Bioreactor. A bioreactor is basically a device in which the organisms are cultivated to form the desired products. it is a containment system designed to give right environment for optimal growth and metabolic activity of the organism.
A fermentor usually refers to the containment system for the cultivation of prokaryotic cells, while a bioreactor grows the eukaryotic cells (mammalian, insect cells, etc).

Biotechnology and its applications
Introduction:
Biotechnology is the broad area of biology, involving living systems and organisms to develop or make products, or "any technological application that uses biological systems, living organisms, or derivatives thereof, to make or modify products or processes for specific use“.
Depending on the tools and applications, it often overlaps with the (related) fields of molecular biology, bio-engineering, biomedical engineering, biomanufacturing, molecular engineering, etc.
The wide concept of "biotech" or "biotechnology" encompasses a wide range of procedures for modifying living organisms according to human purposes, going back to domestication of animals, cultivation of the plants, and "improvements" to these through breeding programs that employ artificial selection and hybridization. Modern usage also includes genetic engineering as well as cell and tissue culture technologies.
Its Applications:
Biotechnology has applications in four major industrial areas,
Food Industry
Health and Medicine
Agriculture
Industrial And Environmental
Biotechnology with agriculture is very useful in now a days and also in upcoming days. With the help of biotechnology we can produce better quality of crops and also increase the yield. The produces are also free from pests.
Genetically Modified Organisms and BiotechnologyMorrisCenteno2
A genetically modified organism contains DNA that has been altered using genetic engineering. Genetically modified animals are mainly used for research purposes, while genetically modified plants are common in today’s food supply.
Biotechnology is a field that merges concepts from biology with ideas of technology. It is broken down into four disciplines often represented by specific colors: red, white, blue, and green. These colors represent medical, industrial, marine, and agricultural processes, respectively.
Biotechnology is particularly important in the field of medicine, where it facilitates the production of therapeutic proteins and other drugs. Synthetic insulin and synthetic growth hormone and diagnostic tests to detect various diseases are just some examples of how biotechnology is impacting medicine.
In the Philippines, the lack of storage facilities, farm-to-market roads, and equipment needed to prevent losses from exposure, pests, and natural deterioration have been perennial issues for Filipino farmers.

The three important techniques of biotechnology are: (1) Recombinant DNA Technology (Genetic Engineering) (2) Plant Tissue Culture and (3) Transgenic (Genetically Modified Organisms).
7. Development of of crops with increased nutritional value
Rice with beta carotene- gene taken from daffodils (modification requires the
introduction of four secific genes)
