Fermentation is a process that uses microbes, to break down compounds to create products like protein or alcohol. This allows for basic raw ingredients such as glucose, starch, carbon monoxide or methane to be used to produce complex food like protein.

Traditional fish food for farmed fish is largely comprised of wild fish or soy. This leads to overfishing and massive amounts of land use for the growing of soy. By using industrial scale fermentation, you can vastly reduce the land and water needed to produce fish food. This technology could also be used to feed other kind of livestock as well.

This sound great, but they do not explain a whole lot in the article. Would you explain more about;

What are these protein substances that we would see in one of the fermenters? Is it a goopy film that is dried?

What are the microbes being fed / What input materials are being turned into protein?

How does carbon monoxide end up in protein?

​

Black Soldier Fly production are great at turning organic matter into proteins and fats, but they can not handle a lot of fibrous plant matter, but they would probably love these fermented leftovers.

So methane it is.

>How does carbon monoxide end up in protein?

Complex chemical reactions being used by the bacteria transforming the substance into protein. Basically, a large bioreactor.

Hard to say, there's a dozen different types of this processes using different microbes, different feedstock , some of it is being trade secrets, you need to actually go inside the factory to know the details. The final product is basically pellets, but there's no telling what by-products are produced, or the steps taken to process it into the pellet form. It just opened after all and this kinds of industrial protein factories aren't very common. Maybe in 10 years when there's thousands of this factories across the world, we'll know more about it.

It uses only methane as the carbon source, not food or agricultural byproducts. This process has a lot of potential if the efficiency is high enough and they could potentially expand production to other valuable organic compounds.

ThrowAwayGenomics t1_itimyti wrote

It’s methane fermentation, so methane is the only carbon/energy source. Depending on processing, you end up with something similar to brewers yeast you find at some grocery stores or a more purified protein powder. For animal feed it would likely be the former. Inputs are methane, salts, water and electricity to the run the bioreactors. I assume there’s some amount of pure oxygen or nitrogen supplementation to reach the most efficient ratios.

Looks like now we can turn fossil fuels into food. This will probably be useful for an offworld colony.

Why don't they just make stuff like this to feed humans instead of animals/fish and somehow make it palatable?

It's complicated, but the answer is mostly social acceptability. We've had the technology to synthetize edible fats from hydrocarbons since the 1940s. We're not doing it because we currently don't need to, and people prefer eating plant and animal based fats. I've seen a recent scientific article theorizing that we could make a factory for a few billion dollars that could make enough edible fat for all human beings in an apocalypse scenario. https://www.coloradohistoricnewspapers.org/?a=d&d=EVE19460906-01.2.29

That's great news considering how seafood takes up 40% of their total protein consumption. To make matters "worse", they are still consuming barely half of what Americans consume protein wise so they still have a long way to catch up which they want with an increased personal wealth.

We are. Companies with alternative meat like beyond meat and impossible foods are actually producing soy protein hemoglobin through yeast in giant fermentors. It is added to make alternative meat more.. “real”. We are getting a lot better at making good tasting things this way, it will just take a while and a lot of investment.

Economics always get in the way. No one wants to pay $10 /lb for Chumbucket patty when they can pay $3/lb for the krabby patty. This means it takes much longer for chum bucket to scale and improve its product.

There's a company in Canada, I think called Pond Biotech, that channels emissions from thermal power plants and cement plants into giant water tanks to grow algae. There are LED lights in the tanks. Algae can be used to make biofuel or animal feed.

So? Pumping it out of the ground isn’t harmful. Setting it on fire IS harmful.

We also recover it from our garbage dumps. Methane is in a lot of places. You can make a closed loop from a city composting collection project. Many cities do this and burn the methane in generators as that is the better alternative but it releases co2. Make fish food instead.

IMSOGIRL t1_itjq2xf wrote

I don't think that's bad news because I think half of the median American protein consumption is about right, considering the penchant for overeating a lot of Americans have. Keep in mind:

42% of Americans are obese.

31% of Americans are not obese but are overweight.

https://www.niddk.nih.gov/health-information/health-statistics/overweight-obesity

So nearly 3 out of 4 Americans are eating too much.

And no, out of those 31%, the percentage of those who are bodybuilders is very tiny. Unless you're literally a bodybuilder with sculpted muscles and try to keep fat as low as possible, if your BMI is too high, you're almost certainly overweight.

They do, it's called tofu. But not everyone likes to eat tofu only, so fish farms exist.

It's why corn and soybeans are is the most plentiful crops in the US but people in the US still eat meat that is fed off the corn and soy.

cazbot t1_itjs2y5 wrote

This tech converts fossil-fuel to fish food. A super unsustainable, bad way to make feed. The USA did this too like 40 years ago and the yeast Pichia pastoris entered the world. We left that technology in the commercial junkyard of bad tech 30 years ago.

Right, yeah. I've had beyond meat at A&W before. Canadian fast food chain. I actually like it a lot more than their real burgers, except for I get a weird chemically taste from subsequent burps which are very unpleasant. Quite odd.

There's also dozens other versions that use combinations of carbon monoxide, hydrogen, nitrogen, carbon dioxide etc etc so there's lots of potential there. Eventually, you could have enough renewables that you're pulling methane out of the air, made from carbon dioxide of the of the air instead of digging it out of the ground.

mutherhrg OP t1_itjupjn wrote

Not many people want to eat raw protein. Doesn't taste good, it's doesn't have the raw taste, texture and "feel" of actual meat. There's probably a major ick factor there too. Might be useful for mixing raw protein into stuff like flour, protein bars or protein powder one day maybe.

Whatever is it, it's better than feeding farmed fish with 3-4 times their weight in wild fish

Tycoon004 t1_itjwezm wrote

There's also that in general, most people vastly over-portion their proteins. If you're talking nutritionally, anything more than a 5oz(~40g protein) steak equivalent portion of a protein is getting mostly wasted. Yet most people probably easily double that for dinner. Do you often have gas, with absolutely raunchy farts? You've got the protein farts, a side effect of protein wasting.

Because humans don’t just ingest raw nutrients into their open mouths like robots. I could replace my grandma’s chicken soup with a scoop of protein powder, two tablespoons of olive oil, and a glass of salty water and get the same nutrients but I won’t do that bc that would be a disgusting and depressing meal. Also I don’t want to be the dipshit telling poor people to eat literal bacteria instead of meat. We’re not supposed to propose starvation rations even worse than crickets.

naossoan t1_itjzujw wrote

I didn't mean it like eating this in it's literal cultured form... But like...IN something.

Also, I'm probably not the best person to discuss it because I do treat food as "something necessary for me to survive" and don't really care in which form that nutrition comes in as long as it doesn't taste like shit. If I could eat Matrix Slop every meal of every day and be in perfect dietary health, I would. Bonus points if I could change the flavour but would be perfectly fine with the "tasty wheat" default flavour described in the film 😂

I consumed nothing but Soylent for over a year straight, soooooo.... Yeah. I don't give a single fuck about food. It's basically something I have to consume in order to continue living. At least that's how I see it.

Pumping it out of the ground is harmful. It contains fossile carbon that should not end up in the atmosphere but it does even when you first feed it to fish and the fish to humans. In the end, it is breathed out and the carbon is in the atmosphere. No difference to being burned.

AnusCleavage t1_itk46mp wrote

Is this based on the idea that protein synthesis maxes out at around 30-40 grams of protein per meal? Because there’s a few new studies starting to pop up due to the rise in popularity of the OMAD diet and intermittent fasting. Not asking to be a dick just genuinely curious if I’ve missed anything and if there’s anything new worth reading on this topic.

That's why he said palatable.

I'm in the same boat. I suck at eating veggies from a taste and texture perspective, so I resort to meat. Would love to swap but tofu and alternative products right now just taste off to me so far. I have cut down on a lot of dairy though, using almond milk and coconut milk and creams for just about everything.

Maybe one day we can eat this protein directly. But the issue is the taste and "ick" factor. We can barely get people to eat a vegan diet, or insects, let alone raw protein sludge. This kind of protein does have the potential to be mixed in other food as supplements, like with flour, protein powder or protein bars.

ThePhysicsOfBaseball t1_itl2rk9 wrote

This isn't an either/or situation. If this catches on we'll just do both.

As a result, the problem is this creates a new demand source that will support and/or drive up prices for methane, encouraging further exploitation both of existing gas wells, reactivation of currently dormant wells, as well as exploration for new gas, right when we should be doing everything we can to reduce our use of petrochemicals.

We're already very good at turning oil into food through the production of ammonia. I'm really not excited by the prospect of finding new reasons to pull sequestered carbon out of the ground, and particularly nat gas given we're incapable of doing so without it leaking (and, between the two options, we are far better off burning methane than releasing it into the atmosphere).

No way that'll ever be as profitable as just using nat gas pulled from the ground. So unless that's paired with a massive carbon tax to make nat gas financially infeasible, you'll forgive me if I'm skeptical.

ThisistheInfiniteIs t1_itl7xvc wrote

Sure, there perhaps may be some responsible ways to do this in the future, but the current reality is that methane pretty much all comes from fracking and drilling and petrochemical wells, which are incredibly destructive and harmful to the environment.

Well, is the objective to feed people, or to feed people high quality fish? Food isn't a fungible commodity, and the fact people simply like meat more is enough to justify the costs, both to the people buying it, and the people making it.

I can tell you as a seafood lover from Louisiana, fish fed with pellets, farmed raised just don’t have the same flavor as wild caught, and aren’t as healthy. Farmed raised Salmon for example aren’t healthy, since they have a higher level of omega 6, bad for the heart. Seafood lovers can taste the pellet.

glaive1976 t1_itpsvi0 wrote

I can believe it, personally the farmed has always been a bit salmon light if you will, so too me the flavor is milder. I fancy the flavor so me it's not as enjoyable, however you may find it more pleasing when it is less pronounced.

I kind of wonder if the down voters are mistaking my preference for being against farming at all. Just in case, I am pro responsible farming. I actually like the idea of this feed as it sounds like major improvement to sustainability.
