RESEARCH PAPER ON BIOLOGICAL ACTIVITY OF ACTINOMYCETES ................ ABSTRACT: The microorganisms are ubiquitous in nature. They are found in probably every environmental condition present on earth. Actinomycetes were originally considered to be an intermediate group between bacteria and fungi but now are recognized as prokaryotic organisms with high G+C (>55%) content in their DNA. Our project aim is to evaluate some biological activities of Actinomycetes like:

Abstract In the asymmetric synthesis of (S)-Ibuprofen‚ the compound is synthesized in nonracemic form directly from an achiral precursor. First‚ racemic ibuprofen was converted to aN achiral ketene via the acid chloride by adding thionyl chloride followed by triethylamine. Then‚ ketene was reacted with a chiral and nonracemic (S)-ethyl lactate produces a mixture of diasteromeric esters of ibuprofen derivatives where (S) configuration is predominantly. Finally‚ hydrolysis of the ester then provides

The technology is licensed by HaldorTopsoe and has been recently demonstrated by San Joaquin Refining in Bakersfield California‚ where a 3‚000 bpsd aromatic saturation unit is in operation.Is

Discussion: In this experiment a ketone‚ 9-fluorenone is reduced to and alcohol. The are two possible ways by which this reduction can occur. One is by a catalytic hydrogenation‚ this uses a catalyst such as palladium or nickel‚ hydrogen gas‚ and heat/pressure. This can reduced an alkane to alkene. This catalytic process is preferred in industrial practices because the cost is low in the long run and more importantly there is little to no waste expense. However‚ hydrogen gas is dangerous due to

HERBS The name herb comes from the Latin word herba. Culinary uses of herbs defer from culture to culture. Every cuisine has its favorite herbs. Mint and dill are used in Middle Eastern cooking‚ lemon grass and coriander in Thai cooking. Sage is a favorite in British pork while the French favor tarragon chicken and fennel with fish. 1) Parsley Parsley is a native to the Mediterranean regions. It is used to make parsley butter and sauce. Chopped and sprinkled over every savory dishes

pestle or a coffee grinder or by using a grater. The grinding enhances the aromatic flavour compounds and makes them easier to process. Toasting and grinding whole spices on the hob is a method used to enhance the aroma and the flavour compounds of whole spices. Oven roasting is mainly used for larger spices with an unusual shape (cassia bark‚ cinnamon‚ star anise) whereas dry roasting in a pan is preferred for smaller aromatic seeds (coriander‚ caraway‚ fennel). Spicer pastes incorporate fresh ingredients

There was successful in 1997‚ when the Department of Agriculture certified three other cultivars of aromatic rice‚ namely‚ KlongLuang 1 and Hawm SuphanBuri and Hawm Phitsanulok 1 in 1998. In the year of 2000‚ Pathum Thani 1 (PTT1) was also certified as one of the off-season aromatic rice varieties (Kwanchai‚ 2001) that are closely in quality

Cyclohexane is a saturated hydrocarbon and cyclohexene is an unsaturated hydrocarbon due to the presence of double bond.Both hydrocarbons produce carbon dioxide and water during combustion test. When the oxygen is limited‚ the product will be carbon monoxide and water. The alkenes are highly flammable and burn readily in air‚ forming carbon dioxide and water. In this experiment‚ the combustion of cyclohexene burns in an orange flame and produces relatively high amount of black soot. The black soot

EXPERIMENT 4: Synthesis of Salicylic Acid from Wintergreen Oil Abstract: The purpose of this experiment is to take methyl salicylate (wintergreen oil) and by heating it under reflux with NaOH as a solvent‚ and then cooling the mixture with H2SO4 as another solvent‚ synthesize salicylic acid. The final step involves purify the product to produce as pure a sample of salicylic acid as possible. This process allowed for the successful production of 1.406g salicylic acid‚ an 82.70% yield.
