Research ArticleOpen accessIn the keywordsRETRACTED: Toxicity Assessment of Phosphonium Based Ionic Liquids Towards Female Guppy FishMohanad El-Harbawi, Yasmin Syazwani Bt. Yusri, M. Ismail HossainIn this study, two phosphonium based ionic liquids (butyl triphenyl phosphonium chloride and hexyl triphenyl phosphonium bromide) have been synthesized using quarternisation process. The toxicities of these Ionic Liquids (ILs) are unknown and may be harmful to humans and the environment. Therefore, the toxicity assessment of these ILs was carried out according to the Organization for Economic Cooperation and Development … …American Journal of Environmental Sciences, Vol. 9, Issue 6 · 20 Jan 2014 · 6,854 accessesView PDFCite
Research ArticleOpen accessIn the keywordsIn Vitro Prevention of Browning in Plantain CultureInnocent Chimereze Onuoha, Chinonye Jemimah Eze, Chibuikem I.N. UnambaProblem statement: The in vitro propagation of plantain (Musa paradisiaca) is still faced with lots of challenges such as blackening or browning of tissues prior to culture due to the oxidation of phenolic compound by polyphenolic oxidase enzyme present in the tissue when excised. Approach: Understanding browning processes in plantain and possible ways of minimizing it during excision of explants … …OnLine Journal of Biological Sciences, Vol. 11, Issue 1 · 6 Jul 2011 · 15,245 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEffect of pH on the Conformation and Biological Activity of Clostridium septicum Alpha-toxin, a Pore-forming HemolysinB.M. Hang'ombe, T. Kohda, M. Mukamoto, S. KozakiThe effects of pH on the pore-forming Clostridium septicum alpha-toxin that causes myonecrosis was assessed at pH 5.0, 7.0 and 9.0 by measuring circular dichroism and its biological activity. Incubation of the toxin at pH 5.0 increased the hemolytic activity measured in murine red blood cells. On the other hand, incubation of the toxin at pH 9.0 drastically reduces the … …American Journal of Animal and Veterinary Sciences, Vol. 2, Issue 2 · 30 Jun 2007 · 6,905 accessesView PDFCite
