Ozone Inhibition of Photosynthesis in Chlorella sorokiniana.
Exposure of Chlorella sorokiniana (07-11-05) to ozone inhibits photosynthesis. In this study, the effects of ozone on O(2) evolution and fluorescence yields are used to characterize this inhibition. At an ozone dose of about 3 micromoles delivered to 2 x 10(9) cells, the photosynthetic rate of the cells is inhibited 50%, as indicated by a decrease in bicarbonate-stimulated O(2) evolution (contr...
متن کاملCarcinogenicity of hexavalent chromium.
Hexavalent chromium (Cr(VI)), a commonly used industrial metal, is a well known human lung carcinogen. Epidemiology and animal studies suggest that the particulate Cr(VI) compounds, specifically the water insoluble compounds, are the more potent carcinogens; however, the carcinogenic mechanism remains unknown. Here we summarize recent Cr(VI)-induced human tumour, in vivo, cell culture and in vi...
متن کاملBiotransformation of Hexavalent Chromium by Acinetobacter iwofii
In the present study, bio reduction of hexavalent Chromium, a transition metal, known for its high solubility and carcinogenicity, using a sewage isolate was tested under controlled laboratory conditions. The objective of the study included determination of the extent of bio degradation of Cr[VI] by the isolate, characterization of the isolate and testing the degradation potential of the isolat...
متن کاملInhibition of Sterol Biosynthesis in Chlorella sorokiniana by Triparanol.
When Chlorella sorokiniana was cultured in the presence of 1 mg/1 triparanol succinate, there was a 42% reduction in total sterol concentration. Algal biomass was reduced by approximately the same amount. In addition to the cycloartenol, cyclolaudenol, 24-methyl-pollinastanol, ergosta-5, 7-dien-3beta-ol, and ergosterol that occur in control culture, pollinastanol, 14alpha-methyl-5alpha-ergost-8...
