Since 2011, massive new strandings of holopelagic Sargassum have been reported on the coasts of the Caribbean, northern Brazil, Guiana, and West Africa, causing severe economic and ecological damage. Three common morphotypes (S. fluitans III, S. nata

Bacterial anaerobic processes in particles in the water column of the northwestern Mediterranean Sea were investigated. Particles concentrated on a filter were incubated in oxygen-free sterile sea water. Results demonstrated that there is a weak but

Two rpoN-linked Delta Tn10-kan insertions suppress the conditionally lethal era(ts) allele. One truncates rpoN while the second disrupts another gene (ptsN) in the rpoN operon and does not affect classical nitrogen regulation. Neither alter expressio
