#KnowledgeByte: Green #NitrogenFixation refers to a variety of emerging methods for producing #Ammonia, the primary ingredient in synthetic fertilizers, without the high energy consumption and fossil fuel dependence of the conventional Haber-Bosch process.

Well, it is steadily happening, because it is cheaper and better.
Regardless of lunacies.What is also interesting is that as the supplies of fertiliser derived from fossil fuel burning to power #NitrogenFixation are interrupted, in the Black Sea and in the Gulf, #containerised nitrogen fixation systems able to run off a stream and a field of solar panels are appearing. I think they are well beyond the prototype stage, though not yet rolling off #production lines onto trucks.

Breaking the triple bonds of N2 to make nitrogen biologically available is a challenge that has only been met by some bacteria and archaea. But they have developed three different types of nitrogenous enzymes. Two new papers show that nitrogenases containing molybdenum are the most efficient, and why.

Today, molybdenum is one of the most common trace elements in the ocean due to oxidative weathering of #Molybdenite. But in the Archean the oceans were reducing, and molybdenum was scarce.
Other nitrogenases evolved to use other transition elements, but Mo-nitrogenase was first, and best.
Molybdenite enables the Earth's biosphere!

#Molybdenite is the primary host for the element molybdenum in the Earth's crust.
Molybdenum is part of the most effective biological molecule for nitrogen fixation (Mo-nitrogenase), which converts atmospheric N2 to a bio-available form.
The grey sphere is Mo; this complex molecule likely evolved more than 3.2 billion years ago.

Discovery of Nitrogen-Fixing Cell-organelle Nitroplast in a Eukaryotic Algae
Biosynthesis of proteins and nucleic acid require nitrogen however atmospheric nitrogen is not available to eukaryotes for organic synthesis............

Scientists discover first nitrogen-fixing organelle
Meaning: #eukaryotes CAN do
#NitrogenFixationwow. A scientific fact I mentioned in several of my books is no longer true. Also, all biology / biochemistry textbooks need to be updated. Oh well. Exciting to see such a major change though.

Plants that survived dinosaur extinction pulled nitrogen from airhttps://www.eurekalert.org/news-releases/1007902 #science #evolution #ecology #plants #NitrogenFixation

#Pleurotus aka #OysterMushroom that lives on a piece of dead wood with not much #nitrogen can produce a large fruiting body that is full of proteins and hence nitrogen. A research study shows that the presence of chicken manure on grass straws does not affect the yield of various species of mushrooms, meaning that these mushrooms do not need to obtain nitrogen from chicken manure. Yet no mushroom has any known enzymes for #nitrogenfixation. This is very puzzling.

I may as well inaugurate my mastodon profile with my post on the crazy history behind #nitrogen N≡N — the wars fought ⛷️, poo mined 🐦 , and science pioneered 🔎 in the quest to sequester it from air to soil:
