A story from last year’s TheRecord.com explains that plastic can now be degraded by natural microbes at an impressive rate. The solution? A high school student figured out he should isolate the most productive strains by testing them on plastic bags.
He knew plastic does eventually degrade, and figured microorganisms must be behind it. His goal was to isolate the microorganisms that can break down plastic — not an easy task because they don’t exist in high numbers in nature.
First, he ground plastic bags into a powder. Next, he used ordinary household chemicals, yeast and tap water to create a solution that would encourage microbe growth. To that, he added the plastic powder and dirt. Then the solution sat in a shaker at 30 degrees.
After three months of upping the concentration of plastic-eating microbes, Burd filtered out the remaining plastic powder and put his bacterial culture into three flasks with strips of plastic cut from grocery bags. As a control, he also added plastic to flasks containing boiled and therefore dead bacterial culture.
Six weeks later, he weighed the strips of plastic. The control strips were the same. But the ones that had been in the live bacterial culture weighed an average of 17 per cent less.
That wasn’t good enough for Burd. To identify the bacteria in his culture, he let them grow on agar plates and found he had four types of microbes. He tested those on more plastic strips and found only the second was capable of significant plastic degradation.
Next, Burd tried mixing his most effective strain with the others. He found strains one and two together produced a 32 per cent weight loss in his plastic strips. His theory is strain one helps strain two reproduce.
“KFC’s claim that its fried offerings have ‘that taste you’ll just love to eat’ is in direct violation of federal regulations,” acting FCC chairman Michael Copps said. “The word ‘eat’ is legally permissible only in reference to substances appropriate for human consumption. Any implication that a consumer could or should ‘enjoy’ a KFC Crispy Strip fails to meet these standards, and presents an unlawful deception to consumers.”

KFC advertisers are reportedly still in negotiations with authorities over whether the word “consumables”—a term that can encompass any product that must be replaced periodically, such as brake pads or swimming pool chlorine—is an allowable substitution for “food.”
The company Soyuzplodoimport seems to have won the argument against Louis Roederer’s champagne. An article in Moscow News explains the trademark dispute between Kristal Vodka and the Cristal Champagne, but it gives an interesting security story as well.
Legend has it that Tsar Alexander II, fearing traditional green champagne bottles could be used to hide an assassin’s bomb, commissioned a brand in a crystal-clear carafe.
Thus Cristal Champagne, with its distinctive flat-bottomed design, was born – though it failed to save the monarch from an explosive end. He survived four assassination attempts but was killed when his carriage was attacked on the streets of St. Petersburg in 1881.
Another fascinating tidbit in the article is that the top rated champagne in a blind taste test by Knights of the Vine was a Novy Svet 2002 Pinot Noir Rose. It costs just $16, whereas Cristal is around $600.
