A QUARTER of a million euros is rather a lot to pay for a hamburger, but that will be the cost of the patty which Mark Post proposes to stick in a bun this October. The burger in question—not so much a quarter-pounder as a quarter-million-pounder—will be so expensive because it will be made from meat that has been grown from scratch in a laboratory.
......................................
Producing meat in Petri dishes is not commercially viable, but Dr Post hopes to scale things up—first by growing the cells on small spheres floating in tanks and ultimately by using scaffolds made of biodegradable polymer tubes, which would both add the third dimension needed for a juicy steak and provide a way of delivering nutrients and oxygen to the steak’s interior.
The nutrients themselves could come from conventional crops, but Dr Post also has plans to use algae, which grow faster than vascular plants, to provide the necessary amino acids, sugars and fats. The upshot would be a world with fewer stock animals. Not only would that liberate land, it would reduce greenhouse-gas emissions (cattle are notorious sources of methane, which is a much more potent greenhouse gas than carbon dioxide). Moreover, you do not even have to kill a cow to obtain stem cells from it. A biopsy will do. That might mean that vegetarians would be able to enjoy meat, too.

Traditional meat production through livestock is rapidly reaching its limits. Worldwide, meat consumption is projected to double in the coming 40 years (source WHO) and already we are using more than 50% of all the agricultural land for meat production. It has also become clear that livestock contributes appreciably to the emission of greenhouse gases such as methane and CO2. Last, the public objection against cruelty to animals will eventually favor a market for cruelty free meat. On the other hand, meat as we know it, is very likely to remain an important item in our food choices.
From all livestock, cows and pigs are the least efficient meat producers with a bioconversion rate of 15%. Through breeding and feeding, the bioconversion rate has reached its upper limit. This inefficiency provides us with a margin to improve meat production provided we move beyond the traditional boundaries of livestock.
Current stem cell technology and skeletal muscle cell biology present opportunities to grow meat in a laboratory “ex vivo” environment with a higher efficiency of converting basic nutrients into edible animal proteins. Already, we are capable of growing pieces of tissue that consist primarily of skeletal muscle from porcine stem cells, derived from muscle biopsies.
There is a tremendous amount of work ahead of us to eventually reach an efficient, cost-effective and high quality meat product, but most of these steps are of a technical nature. Given sufficient effort and resources these technical issues will be solved.
The versatility of the culture process may also result in alternative meat products that for instance contain healthier fatty acids, or are blends of various stem cell sources.
First and foremost however it is essential that a full proof of concept will be provided to attract larger resources to this promising endeavor. We are in the process of growing a first hamburger from bovine stem cells. An update of the state of affairs and of the challenges ahead will be provided.
I myself welcome the day where i will be able to eat steak with low fat very rich tasty flavor and with no cow dead because of it.

Isn't this like feeding methodone to heroine addicts?
(Just a joke!)
I heard about this technology years ago. I'm all for it, as it eliminates the cruelty in commercial animal farming.
I will, however, continue to be vegetarian myself.
RE: Artificial Meat is Comming - Bring4th_Austin - 03-01-2012
It's an interesting idea, but those articles paint a different picture than the one I read on CNN and the one I heard on NPR not too long ago. They both state that with unlimited resources, the technology to create a full serving size more efficiently than conventional livestock production is 10-15 years off. They also said that the meat contains no fat (no taste), so they would have to add it somehow. They also said that the meat itself would be a yellowish color instead of any sort of pink or red, which I think would be a very hard sell to the average consumer.
I'm skeptical but interested to see if they're able to progress it any further. However, this solves very little about our food production system. Conventional crops production is extremely harmful to the environment as well (and, if we're looking at the spiritual aspect, requires the murder of more 2D beings than meat production). For people who choose not to eat meat because of personal ideals, but still wish to eat it, this technology would be good, but I don't see it good for much else. Sustainable systems can easily produce meat and vegetable with nearly no environmental impact...lab-grown meat would help to eliminate conventional livestock production but it definitely wouldn't solve the crux of the problem. I think that the solution to our food production system problems is not in a laboratory, but in the field, where we need to start treating the Earth, the soil, and the animals properly. We also need to educate people on how their dietary choices affect the environment.

Aha I love how general of a word `meat` is...
RE: Artificial Meat is Comming - Ashim - 03-01-2012
I went through a phase with meat substitutes - the product 'quorn' I found to be the best imitation. I only managed to get it in the uk and in luxembourg. The taste was pretty good but after a while I felt a little squeemish.
Since then I tend to stick to fish, fruit, nuts and plenty of water / beer.
I believe that replicating animal flesh for 3d populations is common and requires no slaughtering of 2d entities.
I once made the mistake of trying to force this type of thinking on my wife - with terrible consequences, so place take this as just my opinion.
RE: Artificial Meat is Comming - Ashim - 02-03-2015
We have been testing 'fake' meat products again at home.
There is a new german veggi sausage on the market from Rügenwalder Mühle (Veggi Schinkenspicker) - I could not tell the difference. Excellent product.
This product also looks great and has attracted the financial backing of Bill Gates and the Twitter founders.
RE: Artificial Meat is Comming - native - 02-03-2015
Thanks for posting that Ashim. I can't wait to try the chicken.
RE: Artificial Meat is Comming - AnthroHeart - 02-03-2015
I was wondering if there was fat on this artificial meat. Fat gives it flavor.

If there's fat they will probably use a type of vegetable oil. They probably will have to use fat in order to get the taste right.

that seems like a solid diet.
regards artificial meat - a way of getting meat without having to raise and slaughter an animal. Neat idea, science!
personally, since I went vege a couple of years ago, I've not had any desire/cravings for meat. No suppression of desires etc. So such a product wouldn't be something that I would utilise.

I don't think you are the prime target for this type of product Plenum.
It has been estimated that the demand for meat will continue to increase, partially due to growth economies
such as China and India. Many folks have increased means and see meat not only as a high quality foodstuff
but also as a social status symbol.
Humans, generally will not act to resolve a situation until it is almost too late. This we have seen throughout history.
People, again as a whole will not be 'bullied' into a bad conscience by any form of pro-animal discourse. They mostly
do not really care enough or place their own comfort above that of other factors.
Folks will however act in accordance with fiscal forces.
The focus could well be more on providing a cheap (both for consumer and environment) alternative to real meat
that can pass for and become as accepted as the real thing.
We are not talking "veggie burgers" out of cereals but rather a product that has the feel, taste and smell of flesh.
The true vegetarian or vegan will probably have worked off any cravings for meat, leaving this really a product potentially more
for the masses. I don't think that they are targeting the cottage industry of veggie foods - obviously Mr. Gates and friends do not
invest in such enterprises for 'moral' reasons. They are businessmen and seem to perceive monetary value in such undertakings.

I think you can source at Whole Foods Market if in the states.
Not available in Europe yet.
RE: Artificial Meat is Comming - native - 02-05-2015
There isn't a Whole Foods near by, but I got it at Target. It doesn't taste exactly like chicken but it wasn't too bad. They did a great job. It would make a great substitute in a dish.
There's a mushroom called chicken of the woods (Laetiporus sulphureus, and it's cousin Laetiporus cincinnatus) that is very similar in taste and has the same texture as the above. It's a a great safe beginner mushroom as it's easy to identify (no real lookalikes), easy to spot and it's tasty.
RE: Artificial Meat is Comming - Karl - 02-07-2015
Laetiporus sulphureus / Laetiporus cincinnatus, do they sell spores of these or cultivate them? I'm intrigued
RE: Artificial Meat is Comming - sunnysideup - 02-07-2015
You can cultivate them, especially indoor cultivation has shown good results or so I've read. You can buy Laetiporus sulphureus spawn plugs and try cultivating them yourself. Here's a link where you can find some info: http://everythingmushrooms.com/grow-your-own-mushrooms/chicken-of-the-woods-laetiporus-sulphureus-100-pack/
I've long wanted to give it a try myself, too bad though that I don't have a garden nor an extra room for such experiments.
RE: Artificial Meat is Comming - native - 02-07-2015
Looks like that site is out of stock sunnysideup. There is a third species..Laetiporus conerificola, the west coast species. You can get plugs here. They're grown outdoors.
Or you two could always forage for some..it's a ton of fun! Hunting for morels in the spring is like adult easter-egg hunting and just as fun if not more exciting than when you were a kid. Morels taste similar to steak..it's pretty crazy. Be sure to buy books if you do..two books are preferred as mushrooms often have some variance and different pictures help. Aside from the very easy ones with no look-alikes, you should always have an experienced guide with you. Most areas have regional mushroom clubs you can join. North America has NAMA.
