That article is very confused. They're saying that transglutaminase, street name meat glue, extracted from bacteria is literally the same thing as pink slime. Lean finely textured beef, street name pink slime, comes from cows. However processed, it's still beef. You can't squeeze it out of bacteria.
Reading the Wikipedia articles it's pretty clear these are different things, even if both are added to beef in some way.
