Some green algae are able to use aromatic sulfonic acids (Figure 2.4a) (Soeder et al. 1987) and aliphatic sulfonic acids (Figure 2.4b) (Biedlingmeier and Schmidt 1983) as sources of sulfur. Cultures of Scenedesmus obliquus under conditions of sulfate limitation metabolized naphthalene-l-sulfonate to l-hydroxy-naphthalene-2-sulfonate and the gluco-side of naphth-l-ol (Kneifel et al. 1997). These results are consistent with formation of a 1,2-epoxide followed by an NIH shift. 

Accumulation of organotin compounds in freshwater alga, Sc (Scenedesmus obliquus), and marine alga, Du (Dunaliella salina), is shown in Table 13. It was found that freshwater and marine algae accumulated organotin at a very high level81. 

The relative toxicity of organotin compounds to alga Scenedesmus obliquus is shown in Table 12. Pettibone and Cooney investigated the toxicity of methyltins (MMT MeSnCl3 DMT Me2SnCl2 and TMT Me3SnCl) to microbial populations in estuary sediments in... 

BCF = (cone, of TBT in algae [pg g 1 /(cone. of TBT in supernatant medium 111 g g i. Sc denotes Scenedesmus obliquus-, Du denotes Dunaliella salina. 

Another hydA subtype was found in Scenedesmus obliquus [Florin et al., 2001] and Chlorella fusca [Winkler et al., 2002a] which both belong to the Scenedesmus -clade. Under anaerobic conditions neither S. obliquus nor C. fusca reach the -production efficiency of C. reinhardtii.

Kinetic studies of the incorporation of the " C-labelled precursors mevalonic acid, isopentenyl pyrophosphate, and phytoene into C40 carotenes by Halobac-terium cutirubrum cell-free preparations" produced results consistent with the pathways outlined in Schemes 2 and 3. Only the trans-isomers seemed to be involved. A mutant strain, " PGl, of the green alga Scenedesmus obliquus accumulates phytoene (135), phytofluene (136), and -carotene (137) in place of the...
