Speculative biology is simultaneously a science and form of art in which one speculates on the possibilities of life and evolution. What could the world look like if dinosaurs had never gone extinct? What could alien lifeforms look like? What kinds of plants and animals might exist in the far future? These questions and more are tackled by speculative biologists, and the Speculative Evolution welcomes all relevant ideas, inquiries, and world-building projects alike. With a member base comprising users from across the world, our community is the largest and longest-running place of gathering for speculative biologists on the web.

While unregistered users are able to browse the forum on a basic level, registering an account provides additional forum access not visible to guests as well as the ability to join in discussions and contribute yourself! Registration is free and instantaneous.

Bacterial biochem plausability check

I got a idea for something for a conworld project, and maybe a way to make it work, but I'm unsure of the biochem, and so need a plausablility check.

Would it be possible for a yeast/denitrifying bacteria culture to work in a similar manner to a sour dough yeast/lactobacillus culture, but instead of the bacteria producing lactic acid it would produce nitrogen gas and glutamic acid?

What lead to the idea was a discussion of beer, Guiness to be specific. Draught Guiness gets part of it's texture because it's mixed with nitrogen gas. I wondered if it was possible to have naturally nitrogenated beer, and this seemed like the best way. (The glutimate was just a side thought.)

So, what do you think? Plausable?

Not really my specialty. Try this site http://www.askabiologist.org.uk/.
They may be able to help you.

Thank you, hopefully that gets me a useful answer. (I wasn't quite sure if this was the best place to ask this.)

Sorry, been off.

The nitrogen content of the beer isn't high enough for the culture to have a large enough foothold on nutrients in the area. If other, more 'standard' respirators are around, they'll mean that the culture goes extinct in a very short time.

I think if the company involved could be bothered to both GE this and sterilise fully the surrounding area, it'd be okay.

I think they'd best be GEngineered from cyanobacteria, actually.

But i'm not the best person to ask.
Time flows like a river. Which is to say, downhill. We can tell this because everything is going downhill rapidly. It would seem prudent to be somewhere else when we reach the sea.

I was thinking it might start off with a high protein mash - either a high protein grain or a mash including lentils - to boost the available nitrogen.

So far it sound doable, thank you. :)
