Acute Toxicity Of Mercury And Chromium To Clarias Batrachus (Linn), Azhaguraj Ramakrishnan Jan 2011

Acute Toxicity Of Mercury And Chromium To Clarias Batrachus (Linn), Azhaguraj Ramakrishnan

Azhaguraj Ramakrishnan

Pollution of the aquatic ecosystems by heavy metals is a worldwide problem. In the present study, Clarias batrachus was exposed to Mercury and Chromium for 24, 48, 72 and 96 hrs. The median lethal concentration (LC50) of mercury to C. batrachus for 24, 48, 72 and 96 h of exposure were 1.4 ppm, 1.2 ppm, 1.0 ppm and 0.8 ppm respectively. The median lethal concentration (LC50) of chromium to C. batrachus for 24, 48, 72 and 96 h of exposure were 120 ppm, 115 ppm, 110 ppm and 102 ppm respectively. The acute toxicity levels were derived from LC50 concentrations …

Over the past decades, a number of computational tools for structure prediction have been developed. It is critical that the biological community is aware of such tools and is able to interpret their results in an informed way. Rapid increase in protein sequence information from genome sequencing projects demand the intervention of bioinformatics tools to recognize interesting gene products and associated function often multiple algorithms need to be employed to improve accuracy in prediction and several structure prediction. Here we report the availability of an ABD as a bioinformatics online package dedicated for Insilco analysis of protein sequence and structure …
