Natural indigo dye is extracted from the legume plant Indigofera tinctoria. The process involves over night fermentation of harvested indigo plant using bacteria in specially designed cement moulded ring tank. After fermentation the plant debris are removed and the ferment liquid is oxidised using specially designed mechanical agitator. The precipitated indigo settles down at the bottom of the tank as slurry is collected, boiled and sun dried as indigo cake.\n\nSome more--\n\nAnthraquinone compounds, historically of crucial importance in the dyestuffs industry, have also been identified as secondary metabolites produced by fungi. Secondary metabolites are low molecular weight natural products that have a restricted taxonomic distribution, possess no obvious function in cell growth and are synthesised for a finite period by cells that are no longer undergoing balanced growth. Primary metabolism includes all of the anabolic and catabolic processes that are finely balanced to keep the organism alive. It is essentially an identical process for all living organisms.Many compounds now referred to as secondary metabolites were known and widely exploited prior to modern biotechnology and were mainly obtained from plants. Examples of use are as dyes, perfumes, spices, poisons, pharmacological agents and cosmetics.The occurrence of large scale secondary metabolism is not common to all living organisms, but restricted to certain taxonomic groups. Among animals, arthropods, coral reef coelenterates and other marine invertebrates (e.g. sea urchins and starfish) are the most prolific producers of secondary metabolites. Within the plant kingdom a great abundance of secondary metabolites have been isolated. Few secondary metabolites have been reported in blue-green algae, whereas a rich and extensive secondary metabolism has been observed in bacteria and fungi.Secondary metabolites are thought to have specialised survival functions in nature, being particularly numerous in organisms occupying densely inhabited environments and are believed to have a prominent role in the coexistence and coevolution of species allowing interaction within a community .Despite their diversity, secondary metabolites are all produced from a few key intermediates of primary metabolism. Primary and secondary metabolism are intimately related, with secondary metabolites depending on precursors and energy generated through primary metabolism.The anthraquinone secondary metabolite alizarin is derived from the madder plant. It was exploited as a colorant by man long before the structure was elucidated by Graebe and Liebermann in the 1860s. The anthraquinonoid colorants form the basis of many of the modern synthetic dyes and, after the azo class, they form the second most important group of organic colorants listed in the Colour Index today. Anthraquinone dyes tend to predominate in the violet, blue and green hue sectors in the disperse, vat, and acid application classes of dyes, although they have also made important contributions to mordant, solvent and reactive dyes and also to pigments.Anthraquinone disperse dyes still predominate in the dyeing of cellulose acetate and polyamide substrates, and find use with polyester where other dyes have limitations in application, for example, meeting the extremely high light fastness requirements for very pale colours or for the dyeing of polyester upholstery trim in the automotive sector. However, anthraquinone dyes are at present in decline. This essentially is not a result of any shortcoming of these compounds as dyes, but chiefly because their chemical production is expensive and environmentally unfriendly. Several methods of anthraquinone production have been employed depending on the resources available, but all processes require strong acids, alkalis, high temperatures and heavy metal catalysts.The dyestuff industry is suffering from increases in costs of feedstock and energy for dye synthesis. It is also under increasing

The biotechnology revolution has brought about an unprecedented convergence of biology and technology. In fact, the line between the two fields is increasingly hard to define.  Applied biology, chemical technology and food technology are some examples of fields where knowledge from biology is used to make our life easier, safer and enjoyable.

Biotechnology is a technology based on biology, especially when used in agriculture, food science, and medicine.\n\nOf the many different definitions available, the one formulated by the UN Convention on Biological Diversity is one of the broadest:\n\n"Biotechnology means any technological application that uses biological systems, living organisms, or derivatives thereof, to make or modify products or processes for specific use." (Article 2. Use of Terms) \nBiotechnology can also be defined as the manipulation of organisms to do practical things and to provide useful products.\n\nOne section of biotechnology is the directed use of organisms for the manufacture of organic products (examples include beer, milk products, and skin). Naturally present bacteria are utilized by the mining industry in bioleaching. Biotechnology is also used to recycle, treat waste, clean up sites contaminated by industrial activities (bioremediation), and produce biological weapons.

Biotechnology in one form or another has flourished since prehistoric times. When the first human beings realized that they could plant their own crops and breed their own animals, they learned to use biotechnology. The discovery that fruit juices fermented into wine, or that milk could be converted into cheese or yogurt, or that beer could be made by fermenting solutions of malt and hops began the study of biotechnology. When the first bakers found that they could make a soft, spongy bread rather than a firm, thin cracker, they were acting as fledgling biotechnologists. The first animal breeders, realizing that different physical traits could be either magnified or lost by mating appropriate pairs of animals, engaged in the manipulations of biotechnology. \n\nWhat then is biotechnology? The term brings to mind many different things. Some think of developing new types of animals. Others dream of almost unlimited sources of human therapeutic drugs. Still others envision the possibility of growing crops that are more nutritious and naturally pest-resistant to feed a rapidly growing world population. This question elicits almost as many first-thought responses as there are people to whom the question can be posed. \n\nBiotechnology is “any technique that uses living organisms or substances from those organisms, to make or modify a product, to improve plants or animals, or to develop microorganisms for specific purposes

Biotechnology or BT is industrial application of biology. Its biology in the service of mankind. It involves application of plants, animals and microorganisms in industry.\n\n\nPost-grad courses in BT -\nMSc. in Biotechnology or even Biochemistry has good career prospects. Biotech is a booming sector and the growth oppurtunities are high. The Biotech sector includes - Biopharma, Biotech, Biotech services, Bioindustrial, Bioinformatics etc. After BSc., those who want to go for research, choose MSc. and then go for Phd. On the other hand, some go for MBA-Biotechnology. Career oppurtunities for both these courses are good.\n\nAfter doing MSc. Biotech, one can join R&D dept. of any good Biotech company. US is the best destination for Biotechnology. It stands out in the field of research as well as the biotech market is much developed in the US. Similar, is the case with UK, Canada and a few EU countries. Coming to India and China, these countries are really trying hard. Australia is good study destination as well for BT studies in Asia-Pacific region.\n\nFor details on entrance exams and admission procedures as well as more career options in BT, you may visit -\nhttp://www.biotechworld.cjb.cc\n\nThe other career prospect is MBA-Biotechnology. MBA-Biotech has bright prospects. It is a 2-year programme in management. Only science stream graduates/ those in their final year of graduation can only apply for this course. This course gives equal emphasis to both Biotechnology and management. In India, University of Pune(PUMBA), Amity Institute at Noida are the preferred institutes for this course.

Can you explain your Q more?\nbut I can say genetic regultaion is very important in biotech\nfrom the simplest task like protein expression \n( we need to control the expression by gene regulation such as using lac operon so that the protein which may be toxic or unnatural to the host can be expressed in desirable time)\nto very advance task gene regulation is heavily involved

Biotechnology is technology based on biology, especially when used in agriculture, food science, and medicine. The UN Convention on Biological Diversity has come up with one of many definitions of biotechnology:[1]\n"Biotechnology means any technological application that uses biological systems, living organisms, or derivatives thereof, to make or modify products or processes for specific use."\n\n(http://en.wikipedia.org/wiki/Biotechnology)\n\nBiotechnologists do a number of different jobs, from gene identification and criminal investigations to agricultural research.  Very interesting and rewarding.

Biotechnology is a subject that involves the understanding of the physiology, functions and activities etc of various Biological entities and the use of technology in it to produce better products. \nThe main branches of bio tech are plant bio tech, animal bio tech, genetics, Environmental bio tech, Etc. Each of these branches involves the development of that particular branch with the use of technology.\nMedicines or the medical aspect of biotechnology is found in most of these courses. But the basics has to be genetics if you mean to study human disorders etc.\nBiotechnology has a good future as biotech products are now in demand. Also biotechnologists are needed in researches, Pharmaceutical companies, And various biotech companies itself.

Biotechnology is being used to address problems in all areas of agricultural production and processing. This includes plant breeding to raise and stabilize yields; to improve resistance to pests, diseases and abiotic stresses such as drought and cold; and to enhance the nutritional content of foods. Biotechnology is being used to develop low-cost disease-free planting materials for crops such as cassava, banana and potato and is creating new tools for the diagnosis and treatment of plant and animal diseases and for the measurement and conservation of genetic resources. Biotechnology is being used to speed up breeding programmes for plants, livestock and fish and to extend the range of traits that can be addressed. Animal feeds and feeding practices are being changed by biotechnology to improve animal nutrition and to reduce environmental waste. Biotechnology is used in disease diagnostics and for the production of vaccines against animal diseases.\n\nClearly, biotechnology is more than genetic engineering. Indeed, some of the least controversial aspects of agricultural biotechnology are potentially the most powerful and the most beneficial for the poor. Genomics, for example, is revolutionizing our understanding of the ways genes, cells, organisms and ecosystems function and is opening new horizons for marker-assisted breeding and genetic resource management. At the same time, genetic engineering is a very powerful tool whose role should be carefully evaluated. It is important to understand how biotechnology - particularly genetic engineering - complements and extends other approaches if sensible decisions are to be made about its use.\n\nThis chapter provides a brief description of current and emerging uses of biotechnology in crops, livestock, fisheries and forestry with a view to understanding the technologies themselves and the ways they complement and extend other approaches. It should be emphasized that the tools of biotechnology are just that: tools, not ends in themselves. As with any tool, they must be assessed within the context in which they are being used.

Food dyes can be both according to the FDA.  From the FDA website:\n\n"Technically, a color additive is any dye, pigment or substance that can impart color when added or applied to a food, drug, cosmetic or to the human body. \n\nThe Food and Drug Administration (FDA) is responsible for regulating all color additives used in the United States. All color additives permitted for use in foods are classified as "certifiable" or "exempt from certification" (see Table I). \n\nCertifiable color additives are manmade, with each batch being tested by manufacturer and FDA. This "approval" process, known as color additive certification, assures the safety, quality, consistency and strength of the color additive prior to its use in foods. \n\nThere are nine certified colors approved for use in food in the United States. One example is FD&C Yellow No.6, which is used in cereals, bakery goods, snack foods and other foods. \n\nColor additives that are exempt from certification include pigments derived from natural sources such as vegetables, minerals or animals, and man-made counterparts of natural derivatives."
