Abstract

The growth characteristics and the properties of the Enterococcus faecium (E. faecium) isolated from intestine of slaughting pig were examined in order to confirm whether it will be used practically as probiotics or not. E. faecium was identified by morphological and biochemical tests including of final confirming by API strep kit. Among 264 samples, 44 isolates (16.7%) of E. faecium were observed as an exellent growth as a range of $1{\times}10^7CFU/ml{\sim}3.3{\times}10^9CFU/ml$ in viable bacterial count on MRI medium. All isolates were shown non-haemolysis on the blood agar exception of 28 isolates shown ${\alpha}$-haemolysis and were identified as E. faecium by biochemical test using API strep enzyme kits. Eight strains (18.2%) were finally selected from which they were excellent sensitivity in showing of the acid-tolerance and the bile-tolerance in compare with reference strain.
