When I decided to indulge in field of allelopathy, I selected sunflower as a donor species because of several reports of its ability to suppress other vegetation. The plan was to use this power of sunflower against unwanted plants. In search for natural alternatives for weed management, three sunflower cultivars were investigated for their allelopathic potential first through laboratory bioassays against five most problematic weeds of wheat. The studies were extended to green house and then field experiments and the results indicated the potential of sunflower allelochemicals as...

Cyclosporin A is the major component of the Cyclosporins, a group of nonpolar cyclic oligopeptides possessing immunosuppressive activity. Cyclosporin A is used extensively in the prevention and treatment of graft-versus-host reactions in bone marrow transplantation and for the prevention of rejection of kidney, heart, and liver transplants. As its role in transplantation surgery increases, the demand on industry to improved yields intensifies. In order to obtain and maintain a competitive economic position for new and existing fermentation respectively, it is also necessary to find means for...

Cyclosporin A is a cyclic peptide and was originally isolated from a soil fungus. The compound is typically used to reduce the bodys natural immunity in patients who receive kidney, liver and heart transplants and can also be used to treat severe cases of psoriasis and rheumatoid arthritis diseases. Cyclosporin A is in common usage for kidney and other organ transplants as an anti-rejection medicine. So its importance can not be denied. In the present work, nine local strains of Aspergillus terreus were tested for the production of Cyclosporin A and one best among them was selected for...
