heh, im usin PLA too! but my specs are different to yours..

Enzyme used - fermenting bacteria
Uses - food packaging
properties - transparaent, disposable, strong, flexible, heat resistant.
All those properties are probably correct, and judging by the properties it could easily be used for food packaging.
The bacteria is alcaligenes eutrophus though. I strongly urge you to call it that

Lactic acid is the monomer, not the enzyme.

Lactic acid monomers link in condensation polymerisation (water eliminated) forming polyLACTIC ACID

I'm doing PHBs too and i'm getting by just calling the enzyme A. Eutrophus. If you want to talk about developments, say there are studies into genetically modify potatoes to produce PHB stores rather than starch. And i think there was something about corn as well.

Oh well. I'm sticking with A Eutrophus and Clostridium. I'm not sure about the environmental stuff but i can tell you that PHBs are about 4 times more expensive than just using polypropylene.
