“…As indicated in previous studies, the distinct phases of the life cycle in the green alga Haematococcus lacustris showed different sensitivity to the influence of the heavy metal ions copper (Braune et aI., 1994) and nickel (Xylander and Braune, 1994). Similar results were obtained with mercury ions.…”

“…As indicated, cell division in the flagellate stage was more inhibited by Hg2+ than was germination. This was also observed in studies on the influence of copper (Braune et aI., 1994) and nickel (Xylander and Braune, 1994) on the developmental cycle of Haematococcus lacustris. The varying heavy metal sensitivity of flagellates and aplanospores might be explicable by differences in morphological and biochemical factors.…”

“…The phototactic orientation was determined using a computer-controlled video tracking system (Hader and Lebert, 1985). The procedure of measurement principally followed methods already described in detail (Braune and Ekelund, 1990;Xylander and Braune, 1994). After preparing the test suspension from the stock culture, the flagellates were transferred to a flat glass chamber (0.2 mm) made from a microscopic slide and sealed with a coverslip.…”

The influence of mercury ions on germination of the resting cells (aplanospores) and on cell division, cell structure, phototaxis, and photosynthesis during the flagellate stage of Haematococcus lacustrls was investigated. Aplanospores possess a higher tolerance against mercury ions than flagellates. The reason could be seen in the thicker wall of the resting cells which possibly provide a detoxifying effect by immobilisation of Hg 2 +. This is confirmed by a normal phototactic orientation of flagellates formed from Hg 2+-influenced aplanospores. In contrast, a direct addition of Hg2+ (0.1 to 111M) to the flagellate stage induced an immediate loss of the flagellates to react phototactically. but it was interesting that the inhibition was overcome with time. Obviously, these Hg 2+ concentrations influence only the sensory transduction chain, whereas the energetic background is not injured because the velocity of movement and the percentage of motile cells were scarcely affected. This is supported by the high level of the photochemical efficiency of photosystem II, which remains unchanged at 111M Hg 2+ . Recovery of photosynthesis from inhibition by 10llM Hg 2+ suggests a connection between Hg 2+ influence and metabolism of the 0 1 protein in the reaction centre of photosystern II. The Hg 2+ effect was reversed with time in light, but not in darkness, and streptomycin, an inhibitor of chloroplast protein synthesis, prevented recovery. In flagellates, showing no reactivation, exposure to 10llM Hg 2 + caused cell swelling, a loss of the flagella, and a disorganisation in structure of the chloroplast and of nucleus.

“…A. pallida had a maximum of 3 % of cells showing cell division in 25 % sewage water, but there was no cell division in both algae with other other chemical treatments. Cell division in Haematococcus lacustris was inhibited by nickel at 100 mmol/L (Xyländer and Braune 1994); the same was observed in Chroococcus minor, Gloeocapsa aeruginosa, and Aphanothece nidulans by water stress (Agrawal and Pal 2003).…”

Fourteen blue-green and green algae survived for widely different time periods ranging between 22-102 d in control culture medium. Irrespective of their long or short survival period in control cultures, their pro- or eukaryotic nature, their different morphological types or natural habitats, they all survived for a short time period ranging between 3-8 d in sewage water, 5-10 d in fertilizer factory effluent, (1/4)-2 d in brassica oil, (1/2)-2 d in phenol, 1-3 d in toluene, and 1-4 d in benzene (showing the relative toxicity of different chemicals to different algae, and the antialgal nature of brassica oil). Dilution decreased the toxicity of these agents very little, indicating that they all were very toxic to algae. None of the agent induced the formation of any reproductive or dormant cells. Sewage water, fertilizer factory effluent, brassica oil and/or benzene favored the formation of necridia cells in Phormidium bohneri, P. foveolarum, Microcoleus chthonoplastes, Lyngbya birgei, and L. major filaments. Scenedesmus quadricauda shed off all spines earlier, Hormidium flaccidum fragmented less or not at all, Scytonema millei formed no false branch and heterocyst, Aphanothece pallida and Gloeocapsa atrata cells did not divide, Cosmarium granatum cells did not form any zygospore and Oedogonium sp. not any oogonia-like cells under all or most of treatments with 25-100 % sewage water, 1-100 % fertilizer factory effluent, 1-100 % brassica oil, 25-100 % phenol, toluene and benzene.

“…Changes in the relative abundance of fatty acids in marine macroalgae due to Cu has been observed by Jones and Harwood (1993). Xylander and Braune (1994) reported a decrease in protein and carbohydrate content in the marine alga Haematococcus in the presence of Ni. Metal-induced depurination of DNA has also been reported (Schaaper et aI., 1987).…”
