In the present study we detected unicellular diazotrophic cyanobacteria along a nutrient gradient in New Caledonia’s coral lagoon (24 000 km2) using whole-cell hybridization of specific Nitro821 probes (TSA-FISH, Tyramide Signal Amplification of Fluorescent In Situ Hybridization). The specificity of this probe was confirmed on cultures and in the natural environment. Surprisingly, the community of Nitro821-targeted cells was numerically dominated by picocyanobacteria (97%, 1 to 1.5 μm). These… CONTINUE READING
