Future Factories of America - It's the small things that count

Under the title, "Nanotube-producing bacteria show manufacturing promise", EurekAlert.org tells about bacteria producing nanotubes. I think this is just the tip of the iceberg.
In the not too distant future, most of our chemical factories will be replaced with vats of genetically engineered bacteria cranking out our needs.
Today, algae are being breed/engineered to produce oil that will be converted into something like gasoline. In the future the algae will just directly produce gasoline.
Most anything chemical we need could be produced from our tiny friends. But you ask, "What about milk?". Yep. It's not inconceivable that bacteria could be engineered to produce reliable, consistent, yummy white stuff. This would reduce a plethora of greenhouse gases. Creating the feed for cows creates lots of greenhouse gases. The cows themselves emit methane, a powerful greenhouse gas.
The revolution in chemical production is coming. Grab a hot chocolate-chip cookie and glass of cold milk, and prepare to be marveled.
