| prokaryotic community structure in algal photosynthetic biofilms from extreme acidic streams in río tinto (huelva, spain). | four algal photosynthetic biofilms were collected from the río tinto (sw spain) at four localities: ag, euglena and pinnularia biofilms; ang, chlorella and pinnularia biofilms; ri, cyanidium and dunaliella biofilms; and cem, cyanidium, euglena and pinnularia biofilms. community composition and structure were studied by a polyphasic approach consisting of 16s rrna analysis, scanning electron microscopy by back-scattered electron detection mode (sem-bse), and fluorescence in-situ hybridization (fi ... | 2008 | 19204897 |
