Re: Say what?
I still think it's not genetically engineered. Having checked two different Quorn product packages last night, there's no mention of it being so. Furthermore, the Quorn website explicitly says not in its FAQs page:
> "Are Quorn products non GMO?
> "At Quorn, we’re passionate about providing meat free products with non-GMO ingredients. Mycoprotein, the key ingredient in Quorn products is not genetically modified. All other ingredients used are purchased to a specification which requires that they are not genetically modified."
Furthermore - from my reading of various descriptions on the internet - while ICI was involved, this didn't involve passing on the organism. Rather it was a new isolate; ICI supplied fermenters and expertise in the process.
However, what I think we have here is essentially a semantic difference. The process you referred to for improving carbon flux is what I described as strain improvement. In Europe, the distinction is that you can *select* for variants and even randomly mutagenise a creature and it is *not* classed as genetic engineering. Genetic engineering is where you have some idea about what you want to do - knock out a particular gene or put a new gene in, whatever - and go about that with directed techniques to make that change specifically.
According to wikipedia, in America this may all be considered genetic modification and is lumped together. Presumably that means all dog breeders, say, and any gardener who produces a new variety of flower, etc., are genetic engineers - so the term is basically worthless. Which is fine for them since they don't seem to do scare stories about genetic engineering anyway.
