Stem Cell Meat Burgers Could Be Grown In Bioreactors

Breakthroughs in cultured meat production might enable greener food production without sacrificing burgers and steaks.

As a vegetarian, I'll occasionally hear jokes about how it's still totally okay for me to eat McDonald's burgers. "Why not?" they ask. "It's not like there's actual meat in them anyway!" While that's a slight exaggeration, in a couple of decades it may not be far-fetched. Cultured meat, food literally grown from stem cells instead of traditional farming techniques, is something scientists have been striving for since the 1930s; <a href=http://www.theaustralian.com.au/news/health-science/test-tube-meat-sciences-next-leap/story-e6frg8y6-1111112859219>Winston Churchill even considered it to be an inevitable development. And before everyone starts crying "Soylent Green", science is already making cultured meat today, it's just not financially feasible to produce on a large scale. According to biologists Cor van der Weele and Johannes Tramper however, the system might work on a smaller-scale, specifically with individual bioreactors growing "meat" for 2500 people every year.

The current technique of growing meat from stem cells was introduced by Mark Post in 2013, although it wasn't exactly efficient; <a href=http://io9.com/lab-grown-burger-will-be-the-most-expensive-ever-served-940038258>a single patty grown this way would cost about $385,000. Van der Wheele and Tramper's model uses bioreactors to facilitate exponential cell growth, at which point meat could be harvested, pressed, and divided into consumer-sized portions. Assuming that losses are kept to a minimum, each bioreactor would produce 25,600 kilograms of cultured meat per year, roughly equaling 10 kilograms per person for a village of 2,560. Presumably larger populations could then be served by additional bioreactors, which would have the additional benefit of creating local jobs.

Under this model, large-scale factory farms could be replaced with smaller urban farms, where companion animals are raised for donating muscle stem cells instead of slaughter. Unfortunately, cost effectiveness is still a problem. Pricing cultured meat as though it were regular meat would only earn $175,360 per bioreactor. Now consider that each reactor requires at least three technicians for the year, not to mention any operational costs that may build up. Unless the price of meat goes up we probably won't see cultured meat produced quite this way, but it is a model that could be improved upon in future generations.

What do you think? Is cultured meat something that will never take hold? Or will I be meeting friends for McDonald's burgers in the near future?

I've always liked the idea of lab-grown meat; I do sympathize with animals, but not enough to stop eating meat...this kills two birds with one stone (minus the part about killing birds, of course). I'm sure costs will go down drastically as production increases (economies of scale and all that).

But have you seen the cultured meat they have now? That stuff is disgusting...

They need fetal calf/bovine serum for those growth cultures. Synthetic replacements cost a butload. Maybe there is a cheap alternative. Not one that I know of but then again I'm far from all knowing. Still without an alternative this kind of thing would kind of defeat the point.

The source article mentioned using muscle stem cells, which sounds like they could be extracted relatively painlessly, although it might not work on a larger scale. You'd definitely need a solid cell bank though.

There's another alternative out there, that's both environmentally friendly, animal friendlier and financially viable.

Maggots.

There's a certain species of Icelandic fly that'll eat just about anything. And all that food is converted straight into maggot-offspring. Unlike most animals we eat where only a relatively small part of the animal is fit for human consumption almost the entire maggot is pure easily digestible protein. You can keep these flies in a tank, feed them with all your biological waste and they'll breed a constant supply of edible maggots.

Only problem, they're maggots. Would you eat them?

Oh my God...Shadowrun is becoming reality more and more each year.
This is how the soy-line starts.

Now I'm just waiting on the Shiawase Decision....oh wait, that kinda already exists in Disneyland.

All this really means is that we need to do more research into the area. There was a point in time when Aluminum was more expensive was gold and royalty ate on aluminum plates as a status symbol. Now thanks to refining/processing techniques for the ore we now have Reynolds wrap aluminum foil that we throw away with out even thinking about it.

At the end of the day the two expensive argument is the worst argument when it comes to deciding if you should pursue research in a particular ares of study.

eum true but not what I mean. The cells are cultured in a liquid growth medium. They add fetal calf/bovine serum to it. To the growth medium. As in serum extracted from their blood. And you need a lot of it for a bioreactor. Tapping a cow every few weeks for a bit of its blood, extract serum (and optionally put the blood cells back) is not what they do today. Kill the cow, take all its blood, extract the serum. That is what they do.

Yea I'm with you there. Easier said then done though. They never had a REAL incentive op to now but it has been researched already. Nothing cost effective yet.

Sorry. I make plenty of typos myself. I shouldn't jab. But I just can't help it.

Unless you can also culture fatty tissue, that's going to be some flavorless meat.

Having said that, I'd rather have a future where vat-grown meat is the norm, as opposed to whatever events allowed Transmetropolitan to have such questionable cuisine decisions (monkey burger, long pig, etc.)

Quite all right. Thanks for pointing it out.

history has proven that with enough abstraction, most humans will eat ANYTHING

shape it into a patty and put it on a bun, they don't want to think about where it came from ;)

As long as it tastes just as good as the real thing. Then fine, I'll give it a shot. But if it doesn't, I'll still go real.

I'm of the opinion that the food chain is natural. The notion that we, as evolved predators, should feel bad for our prey is ridiculous. Now, as social beings we can be conscious about avoiding suffering, but the chain is there for a reason. It's not like a hungry lion would think twice about nibbling on my gibblets.

I have a feeling I'll be eating rat burgers from a roadside grill before genetically grown meat becomes something I find in the frozen food aisle and in restaurants.

ITS PEOPLE! CULTURED MEAT IS PEOPLE!!!!

This seems like one of those things that is only aimed at people willing to pay a lot of money to eat suffering free meat.
You know, people that think everything should live forever because when you ask them whats the minimum amount of suffering permitted they respond with "killing the animals for food is just too cruel". You know, the people that don't think plants deserve to live.

yep, and this is why skynet will beat us, because we are this stupid.

I'm all for this if it ever reaches a reasonable price. This could be just another answer to provide an ever expanding source of food for an ever expanding population. My only concern is that they would need a way to make it fatty. Not just because of taste, but because humans die without a sufficient amount of fat intake. It's a necessary macronutrient that no human can exist without. I don't foresee this being an end all of food problems. Also, I doubt whether this kind of thing would ever be viable in countries where food production is an issue. In the US, we have a food surplus, but we are a fully developed nation.
