| lipid biomarkers, pigments and cyanobacterial diversity of microbial mats across intertidal flats of the arid coast of the arabian gulf (abu dhabi, uae). | variations in morphology, fatty acids, pigments and cyanobacterial community composition were studied in microbial mats across intertidal flats of the arid arabian gulf coast. these mats experience combined extreme conditions of salinity, temperature, uv radiation and desiccation depending on their tidal position. different mat forms were observed depending on the topology of the coast and location. the mats contained 63 fatty acids in different proportions. the increased amounts of unsaturated ... | 2008 | 18637042 |
| halotaxis of cyanobacteria in an intertidal hypersaline microbial mat. | an intertidal hypersaline cyanobacterial mat from abu dhabi (united arab emirates) exhibited a reversible change in its surface colour within several hours upon changes in salinity of the overlying water. the mat surface was orange-reddish at salinities above 15% and turned dark green at lower salinities. we investigated this phenomenon using a polyphasic approach that included denaturing gradient gel electrophoresis, microscopy, high-performance liquid chromatography, hyperspectral imaging, abs ... | 2010 | 19919535 |
