India has over 45,000 wild species of plants and 77,000 wild species of animals recorded and these Comprises of about 6.5% of the world’s known wild life. India’s biological heritage is impressive not only in its dynamic diversity, but also in its uniqueness. And biodiversity considering different values like Environmental value, productive value, Ethical an aesthetic values. These values are helpful to human and animal conception and requires major source of food, medicine, horticultural and ornamental uses, timber, fiber, dyes and other chemical, fuel uses. This need not be surprising considering the fact that in the last few decades. And India has lost at least 50% of its forests. In addition overexploitation, hunting of natural sources, is poisoning by pesticides, excessive botanical and zoological collection, displacements by exotics causing biodiversity loss. In this point of view Biotechnology can play an important role in culturing and conserving biodiversity. The taxonomic systems based on DNA and RNA sequence data is main basis for biodiversity characterization and assessment. It has working big tool for identification of desirable and elite genes located up in wild relatives of domesticated macrobes and microbes. They have further made possible to domesticated taxa to produce transgenic that have increased agricultural biodiversity performance, quantity, productivity, Ecosystem management and resistance to abiotic and biotic stresses of all kinds. In this point of view the current study reveals biotechnology is a tool for conserving biodiversity and Ecosystem balance, improving rare species percentage.

Alginic acid, also called algin or alginate, is an anionic polysaccharide distributed widely in the cell walls of brown algae, where it, through binding water, forms a viscous gum. In extracted form it absorbs water quickly; it is capable of absorbing 200-300 times its own weight in water. Its colour ranges from white to yellowish-brown. It is sold in filamentous, granular or powdered forms. It is a linear copolymer with homopolymeric blocks of (1-4)-linked β-D-mannuronate (M) and its C-5 epimer α-L-guluronate (G) residues, respectively, covalently linked together in different sequences or blocks. The monomers can appear in homopolymeric blocks of consecutive G-residues (G-blocks), consecutive M-residues (M-blocks) or alternating M and G-residues (MG-blocks). Alginate is used extensively as an impression-making material in dentistry, prosthetics, life casting and occasionally for creating positives for small-scale casting. It is also used in the food industry, for thickening soups and jellies. In this paper, explains about the applications of alginates in different industries.

An aromatic herb in the mint family, Thyme leaf grows to a height of fifteen inches with small rounded leaves and pink flowers on woody stems. It is also a good source of iron, phosphorous, potassium, zinc and manganese. Thyme leaves are collected from Kodaikanal hill area. The collected fresh Thyme leaves are washed and remove the immature part. After that the leaves are Shadow dried at 27-37 C and the leaves are made in to powder by using mixture grinder. In order to estimate the micro and macro nutrients such as carbohydrate, protein, fat, calcium, phosphorus, iron and crude fibre of thyme powder. It was found to be rich in iron, phosphorous, small amount of carbohydrate and moderate amount of fat content present in thyme powder. In order to estimate the phytonutrients such as beta carotene, phenol and polyphenol are estimated by quantitative method. The antimicrobial activities of the extracts against various micro organisms were tested by using disc diffusion method. The ethanol extract showed the better result. Whereas, the strong antibacterial inhibition was noted in methanol extracts of Escherichia coli and Staphylococcus aureus. The sensory evaluation was done by a panel of twenty expert using A 5 point hedonic scale. Five recipes were prepared with and without incorporation of the developed thyme leaf powder. Thyme leaf powder was incorporated in 2%,4%,6% level in tea,noodles,pacoda, channa masala and chillie chicken. Only 2% and 4% thyme leaf powder incorporate recipes were acceptable because increasing the amount of up to 1% brought considerable changes in taste of recipes. This result of study encourages the incorporation of this locally available ingredients pumpkin seed in various indigenous products which might be helpful for promoting health

Alginates are cell-wall constituents of brown algae (Phaeophyceae). They are chain-forming heteropolysaccharides made up of blocks of mannuronic acid and guluronic acid (picture left shows high manuronic acid gel, standard gel and high guluronic gel, giving different consistencies). Composition of the blocks depends on the species being used for extraction and the part of the thallus from which extraction is made. Calcium alginate is insoluble in water and this led to the development of fibres that could be woven into various textiles or parts of textiles, and their use in bandages, particularly for large wounds and burns, became widespread. The bandage could be removed much more easily than cellulose-based bandages, as the calcium alginate was soluble in a simple salt solution, and wound disruption was reduced. Modifications of the same principle also allows these fibres to form an important part of firemen’s fire-proof clothing and as part of the fluxes now used in welding rods. . Good quality stable fibers have been produced from mixed salts of sodium and calcium alginate, and processed into non-woven fabric that is used in wound dressings. They have very good wound healing and haemostatic properties and can be absorbed by body fluids because the calcium in the fibre is exchanged for sodium from the body fluid to give a soluble sodium alginate. This also makes it easy to remove these dressings from large open wounds or burns since they do not adhere to the wound.

The purpose of this paper is to identify the metacognitive strategies for the enhancement of mathematical problem solving. This paper portrays the results by historical method. The primary purpose of the enhancement of mathematical problem solving instruction is not to equip students with a collection of skills and processes, but rather to enable them to think for themselves. The value of skills and processes instruction should be judged by the extent to which the skills and processes actually enhance flexible, independent thinking. Students’ abilities to think flexibly can be developed and enhanced by teachers modeling their own thinking processes, giving students opportunities to solve the problem, and helping students become aware of their own thought processes as they solve mathematical problems. This process of analyzing our own thought processes is called metacognition and includes thinking about how we are approaching a problem, the strategies we choose to use to find a solution, and the questions we ask ourselves about the problem are all part of metacognition.
