2 days ago · Vitamin B12 is a vital but scarce commodity in the sea (and elsewhere). It is essential not only for the metabolism of the two bacteria investigated in this study, but for many other marine organisms.
Apr 25, 2024 · The bacteria consume sulfide and nitrogen to become some of the largest bacteria in the world — large enough to see with the naked eye. Previous research had discovered nitrogen loss in the basin over the past few decades. The UCLA researchers wanted to find out whether these microbial mats were the cause.
1 day ago · A groundbreaking study reveals that Rhizobia bacteria can fix nitrogen in partnership with marine diatoms, a discovery that could have significant implications for agriculture and marine ecosystems. Nitrogen is an essential component of all living organisms. It is also the key element controlling
1 day ago · Two species of marine bacteria from the North Sea have established an unusual and sometimes destructive relationship to produce the important vitamin B12. This is reported by researchers from Oldenburg, Germany, and San Diego, US, in the journal Nature.
1 day ago · Vitamin B12 is a vital but scarce commodity in the sea (and elsewhere). It is essential not only for the metabolism of the two bacteria investigated in this study, but for many other marine organisms. “Half of all algal species cannot survive without this vitamin,” Wienhausen explains. Yet like humans, algae cannot produce B12 themselves.
Apr 18, 2024 · This reflects two essential functions, namely the uptake of ferric iron from the environment, and the protection of the bacterial photosystems as ferrous iron. As cyanobacteria typically have two types of proteins for these functions, it is speculated that the presence of a single protein in the cyanobacterium Prochlorococcus that can perform ...
2 days ago · The researchers conducted various experiments to analyse the interaction between two species of marine bacteria from the North Sea in the synthesis of vitamin B12, and have now published their findings in the scientific journal
