Mangroves are pantropical marine forests rooted in soft sediments and subject to pronounced seasonal variability. However, the effects of these hydrological fluctuations on root‐associated prokaryotic communities remain poorly understood, particularly in underexplored regions like the Guianas. In light of increasing climatic extremes, we investigated microbial responses to contrasting hydrological regimes in the Cayenne Estuar...

There is a great scientific curiosity to discover all environments sheltering microalgae, especially those with exceptional characteristics from coldest to hottest ones, the purpose remains to explore the potential of the native microalgae flora and the research for new bioactive compounds. This study aimed to isolate a polysaccharide-producing microalga from an extreme ecosystem and to evaluate its capacity to inhibit the α-...
