Mutagenic & Carcinogenicity of phytoplankton blooming using salmonella typhimorium in Persian Gulf

Planktonic blooming is one of the aspects of biological pollution in marine environment. Due to the harmful effects of this natural phenomenon on the aquatic resources, marine ecosystems and human beings caused by consuming polluted aquatic creatures or by contact with polluted water, another effect of this phenomenon, i, e., mutagenicity and carcinogenicity of planktonic blooming, was investigated. This study was conducted using Ames test with Salmonella typhimurium strain TA97 and microsome. In this research,a sample of red tide (chlamydomonas sp) in the two phases of supernatant and mass was added separately to the minimal agar medium Salmonella typhimurium strain TA97. For comparison, sodium aside and distilled water were used as positive and negative controls, respectively. Counting the colonies and comparing them with those of negative control, the impact of red tide mutagenicity in the supernatant phase was observed. Such an impact was not observed in the mass phase.Carcinogencity microsome of rat liver produced under sterile conditions was added to the minimal agar medium having plank tonic blooming sample and strain TA97. The impact of mutagenicity was not observed when the numbers of produced colonies in the sample, the positive control and the negative control were compared.
