Research ArticleOpen accessIn the keywordsHeat Balance Analysis During the Production of Jadomycin CT. J. Burdock, A. H. Giffin, M.S. Brooks, A.E. GhalyJadomycins are novel antibiotics that exhibit biological activity against bacteria and yeast and also demonstrate cytotoxicity against cancer cells. Jadomycin C was successfully produced from 10 L of fermentation media in a 19 L bioreactor using Streptomyces venezuelae ISP5230 which was shocked with ethanol. The bioreactor temperature and pH were successfully maintained at 30°C and 7, respectively. The heat of … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 1 · 31 Mar 2008 · 7,710 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDetermining the Effect of Sediment Resuspension from the Activity of Phenoloxidase in Penaeid Shrimp Post LarvaeNapaporn Leadprathom, Pornpimon Teangtarn, Kedsiri Ing-kanorn et al.Problem statement: Regular sediment resuspension or dredging in coastal zones can induce stress in a postlaval penaeid shrimp, which affects immune response. Phenoloxidase is a significant enzyme in the penaeid shrimp’s immune system which, when used as a biomarker, can serve as an early warning sign in ecological systems. The stress response of shrimp postlarvae from sediment reuspension was analyzed … …American Journal of Environmental Sciences, Vol. 8, Issue 3 · 12 Jun 2012 · 7,089 accessesView PDFCite
Research ArticleOpen accessIn the keywordsASSESSMENT OF SURFACE WATER QUALITY IN AN ARSENIC CONTAMINATED VILLAGEKumud C. Saikia, Susmita GuptaArsenic contamination of ground water has occurred in various parts of the world, becoming a menace in the Ganga-Meghna-Brahmaputra basin (West Bengal and Assam in India and Bangladesh). Recently arsenic has been detected in Cachar and Karimganj districts of barak valley, Assam, bordering Bangladesh. In this area coli form contamination comprises the major constraint towards utilization of its otherwise ample … …American Journal of Environmental Sciences, Vol. 8, Issue 5 · 31 Aug 2012 · 7,517 accessesView PDFCite
