polymer producing bacteria

[R. Lee Steensland]

Does anyone have ANY informaion about a bacteria that produces a 
biodegradable plastic in its cells?  I heard about them several months 
ago, and I would like to find more information about them.  These bacteria 
were part of a genetics experment I recall.  These particular bacteria 
have a slow growthrate, so scientists removed the polymer gene from that 
bacteria and inserted it into another bacteria with a faster growthrate, 
thereby producing more polymer...

Thanks...
