Biosynthesis of poly(4-hydroxybutyric acid) by recombinant strains of Escherichia coli.

abstract：:Enterococcus faecium, a major cause of nosocomial infections, is often isolated from conditions where biofilm is considered to be important in the establishment of infections. We investigated biofilm formation among E. faecium isolates from diverse sources and found that the occurrence and amount of biofilm formation ...
