<<2/”>a >a href=”https://exam.pscnotes.com/biotechnology/”>Biotechnology is defined as the industrial application of living organisms and their biological processes such as biochemistry, Microbiology, and Genetic engineering, in order to make best use of the Microorganisms for the benefit of mankind. Modern biotechnology provides breakthrough products and technologies to combat debilitating and rare diseases, reduce our environmental footprint, feed the hungry, use less and cleaner energy, and have safer, cleaner and more efficient industrial manufacturing processes.

Biotechnology began in the 1970s after the development of genetic engineering that allowed scientists to modify the genetic material of living cells. Genetic engineering is the manipulation of DNA Molecules to produce modified Plants, animals, or other organisms. DNA is the part of a cell that controls the genetic information of an animal or plant. DNA is a double-stranded molecule that is present in every cell of an organism. The genetic information is contained in individual units or sections of DNA called genes. The genes that are passed from parent to offspring determine the traits that the offspring will have.

Applications of Biotechnology

  1. Health and medicine

Fighting infectious diseases : Biotechnology is used extensively in the study of infectious diseases such as SARS (Severe Acute Respiratory Syndrome), and influenza. As a result more effective pharmaceuticals have been developed.

Development of Vaccines and antibiotics : Using technology, microorganisms are used to develop antibiotics and vaccines to cure diseases. For example, bacteria Bacillus polymysea is used to produce polymyxin B (antibiotic used to cure urinary tract infections), fungus Penicillium notatum is used to produce penicillin (used to cure pneumonia, and many other bacterial infections.)

Treating genetic disorders : Disease can occur when genes become defective due to mutations. With advancements in biotechnology, in the near future it will be possible to use gene therapy to replace an abnormal or faulty gene with a normal copy of the same gene. It may be used to treat ailments such as heart disease, inherited diseases such as SCID, and Thalassaemia.

In forensic science : A lot of New techniques have been developed such as DNA fingerprinting, besides having a number of other applications which have facilitated the speedy identification of the criminals.

  1. Environment

Cleaning up and managing the environment : Cleaning up the environment using living organisms is called bioremediation. Naturally occurring, as well as genetically modified microorganisms, such as bacteria, Fungi and ENZYMES are used to break down toxic and hazardous substances present in the environment.

  1. agriculture

Biotechnology In Agriculture

For about 10,000 years , farmers have been improving wild plants and animals through the selection and breeding of desirable characteristics. This breeding has resulted in the domesticated plants and animals that are commonly used in crop and Livestock agriculture. In the twentieth century, breeding became more sophisticated, as the traits that breeders select for include increased yield, disease and pest resistance, drought resistance and enhanced flavor. Traits are passed from one generation to the next through genes, which are made of DNA. All living things—including the fruits, vegetables and meat that we eat—contain genes that tell cells how to function. Recently, scientists have learned enough to begin to identify and work with the genes (DNA) that are responsible for traits.

Agricultural biotechnology is a collection of scientific techniques used to improve plants, animals and microorganisms. Based on an understanding of DNA, scientists have developed solutions to increase agricultural productivity. Starting from the ability to identify genes that may confer advantages on certain crops, and the ability to work with such characteristics very precisely, biotechnology enhances breeders’ ability to make improvements in crops and livestock. Biotechnology enables improvements that are not possible with traditional crossing of related species alone.

Technological aspects of agricultural biotechnology

Genetic engineering

Scientists have learned how to move genes from one organism to another. This has been called genetic modification (GM), genetic engineering (GE) or genetic improvement (GI). Regardless of the name, the process allows the transfer of useful characteristics (such as resistance to a disease) into a plant, animal or microorganism by inserting genes (DNA) from another organism. Virtually all crops improved with transferred DNA (often called GM crops or GMOs) to date have been developed to aid farmers to increase productivity by reducing crop damage from Weeds, diseases or insects.

Molecular markers

Traditional breeding involves selection of individual plants or animals based on visible or measurable traits. By examining the DNA of an organism, scientists can use molecular markers to select plants or animals that possess a desirable gene, even in the absence of a visible trait. Thus, breeding is more precise and efficient. For example, the International Institute of Tropical Agriculture has used molecular markers to obtain cowpea resistant to bruchid (a beetle), disease-resistant white yam and cassava resistant to Cassava Mosaic Disease, among others. Another use of molecular markers is to identify undesirable genes that can be eliminated in future generations.

Molecular diagnostics

Molecular diagnostics are methods to detect genes or gene products that are very precise and specific. Molecular diagnostics are used in agriculture to more accurately diagnose crop/livestock diseases.

Vaccines

Biotechnology-derived vaccines are used in livestock and humans. They may be cheaper, better and/or safer than traditional vaccines. They are also stable at room temperature, and do not need refrigerated storage; this is an important advantage for smallholders in tropical countries. Some are new vaccines, which offer protection for the first time against some infectious illnesses. For example, in the Philippines, biotechnology has been used to develop an improved vaccine to protect cattle and water buffalo against hemorrhagic septicemia, a leading cause of death for both species.

Tissue Culture

Tissue culture is the regeneration of plants in the laboratory from disease-free plant parts. This technique allows for the Reproduction of disease-free planting material for crops. Examples of crops produced using tissue culture include citrus, pineapples, avocados, mangoes, bananas, coffee and papaya.

Biofertilizers

Biofertilizers are defined as preparations containing living cells or latent cells of efficient strains of microorganisms that help crop plants’ uptake of nutrients by their interactions in the rhizosphere when applied through seed or Soil.  They accelerate certain microbial processes in the soil which augment the extent of availability of nutrients in a form easily assimilated by plants.

Very often microorganisms are not as efficient in natural surroundings as one would expect them to be and therefore artificially multiplied cultures of efficient selected microorganisms play a vital role in accelerating the microbial processes in soil.

Use of biofertilizers is one of the important components of integrated nutrient management, as they are cost effective and renewable source of plant nutrients to supplement the chemical Fertilizers for Sustainable Agriculture. Several microorganisms and their association with crop plants are being exploited in the production of biofertilizers. They can be grouped in different ways based on their nature and function.

Different types of biofertilizers 

Rhizobium

Rhizobium is a soil habitat bacterium, which can able to colonize the legume roots and fixes the atmospheric nitrogen symbiotically. The morphology and physiology of Rhizobium will vary from free-living condition to the bacteroid of nodules. They are the most efficient biofertilizer as per the quantity of nitrogen fixed concerned. They have seven genera and highly specific to form nodule in legumes, referred as cross inoculation group.

Rhizobium inoculant was first made in USA and commercialized by private enterprise in 1930s and the strange situation at that time has been chronicled by Fred.

Initially, due to absence of efficient bradyrhizobial strains in soil, soybean inoculation at that time resulted in bumper crops but incessant inoculation during the last four decades by US farmers has resulted in the build up of a plethora of inefficient strains in soil whose replacement by efficient strains of bradyrhizobia has become an insurmountable problem.

Azotobacter              

Of the several species of Azotobacter, A. chroococcum happens to be the dominant inhabitant in arable soils capable of fixing N2 (2-15 mg N2 fixed /g of carbon source) in culture media.

The bacterium produces abundant slime which helps in soil aggregation. The numbers of A. chroococcum in Indian soils rarely exceeds 105/g soil due to lack of organic matter and the presence of antagonistic microorganisms in soil.

Azospirillum

Azospirillum lipoferum and A. brasilense (Spirillum lipoferum in earlier literature) are primary inhabitants of soil, the rhizosphere and intercellular spaces of root cortex of graminaceous plants.

They perform the associative symbiotic relation with the graminaceous plants.   The bacteria of Genus Azospirillum are  N2 fixing organisms isolated from the root and above ground parts of a variety of crop plants. They are Gram negative, Vibrio or Spirillum having abundant accumulation of polybetahydroxybutyrate (70 %) in cytoplasm.

Five species of Azospirillum have been described to date A. brasilense, A.lipoferum, A.amazonense, A.halopraeferens and A.irakense.  The organism proliferates under both anaerobic and aerobic conditions but it is preferentially micro-aerophilic in the presence or absence of combined nitrogen in the medium.

Cyanobacteria

Both free-living as well as symbiotic cyanobacteria (blue green algae) have been harnessed in rice cultivation in India. A composite culture of BGA having heterocystous Nostoc, Anabaena, Aulosira etc. is given as primary inoculum in trays, polythene lined pots and later mass multiplied in the field for application as soil based flakes to the rice growing field at the rate of 10 kg/ha. The final product is not free from extraneous contaminants and not very often monitored for checking the presence of desiredalgal Flora.

Once so much publicized as a biofertilizer for the rice crop, it has not presently attracted the attention of rice growers all over India except pockets in the Southern States, notably Tamil Nadu. The benefits due to algalization could be to the extent of 20-30 kg N/ha under ideal conditions but the labour oriented methodology for the preparation of BGA biofertilizer is in itself a limitation. Quality control measures are not usually followed except perhaps for random checking for the presence of desired species qualitatively.

Azolla  Azolla is a free-floating water fern that floats in water and fixes atmospheric nitrogen in association with nitrogen fixing blue green alga Anabaena azollae. Azolla fronds consist of sporophyte with a floating rhizome and small overlapping bi-lobed leaves and roots. Rice growing areas in South East Asia and other third World countries have recently been evincing increased interest in the use of the symbiotic N2 fixing water fern Azolla either as an alternate nitrogen sources or as a supplement to commercial nitrogen fertilizers. Azolla is used as biofertilizer for wetland rice and it is known to contribute 40-60 kg N/ha per rice crop.

 

  1. Industry

Biotechnology has been used in the industry to produce new products for human consumption. Food additives have been developed which help in the preservation of food. Microorganisms are used in the mass production of items such as cheese, yoghurt, and alcohol.

Biotechnology through Genetic engineering has made Food Crops more resistant to disease, but the mere act of modification of the naturally selected food crops may actually disturb the delicate balance of Biodiversity-2/”>Biodiversity which exists in nature causing a disturbance to the natural balance.

The production of GMOs has negative impacts on the natural ecosystem which are not apparent now but will be apparent in the future. For example, genetic changes in a particular plant or animal might render it harmful to another organism higher up in the food chain and ultimately this effect may build up to destroy the entire food chain in which that plant plays a role.

GMOs have been known to retain some of the genetically modified DNA in the final product made for human consumption. Such remnants of genetic material are harful to human health and can cause production of previously unknown allergens.

Genetically modified plants and animals have the potential to replace traditional farming or say Poultry and meat-producing practices. This will result in destruction of economies based on these products.

In the context of applications of genetic engineering in human life, misuse of this technology in the production of biological warfare or weapons is a very major disadvantage.

Genetic engineering is being used to create human organs but in the long run if it can create genetically modified, perfect human specimens who are better than the creators than this may be disastrous.

Nature selection in man and the resulting diversity of the human genetic pool is essential for the survival of the species. Genetic engineering will interfere with this process too causing unknown complications.

The progress of science in the 20th and 21st centuries exploded, creating technologies that reshaped Society and extended lives. The pace of change was so great that it took society years to start asking questions about the ethics or morality of new developments. Now, humanity is at a major crossroads, where further Investment in biotechnologies could change the way humans live and reproduce. Here are ethical issues attached with biotechnology:

  • the use of genetic information to create medicine contributes to the rising cost of drugs, and shifts attention away from designing affordable drugs available for mass production.
  • Creation of designer babies by manipulating gene is another troublesome issue. Designer babies are children enhanced through gene manipulation to meet certain mental, physical, and emotional demands of parents. The technology does not yet exist to manipulate the entire genome of a fetus, but research continues along this path.
  • Use of stem cells is one of the most controversial issue of biotechnology. creating new lines from embryonic stem cells is akin to abortion, and the destruction of any embryo for research purposes is an ethical violation.
  • With rising use of biotechnology, there is great pressure on the drug approval agency. This pressure of shortening the trial phase can remove the safeguards put in place to keep public safe.
  • The opponents of Genetically modified organism argue that these organism actually put the entire food supply at risk through the homogenization of plant life and the death of biodiversity. They also argue that insects and plant-destroying bacteria or diseases will continue to evolve with the GMOs, resulting in super-pests and super-diseases that are untreatable by modern methods. Finally, doctors argue that GMOs include antibiotics that make their way into the human body. Overconsumption of antibiotics is harmful, because those drugs lose their ability to fight off disease.
  • Biotechnology engineers and companies must find a way to address cost issues and make new advancements more affordable for the Average consumer; otherwise, biotechnology will create a two-tiered society: those who can afford the medical treatments needed to live, and those who cannot.
