Abstract
Bifidobacterium is a group of Lactic Acid Bacteria
(LAB) that commonly found in the gastrointestinal tract and vagina. LAB has
many health benefits, such as produce an antimicrobial substance against a
pathogen. This research aims to isolate Bifidobacterium from an infant’s
feces and know its antimicrobial activity against Escherichia coli and Candida
albicans. A total of 5 isolates Bifidobacterium
spp. were isolated from the sample. The largest inhibitory activity against E.
coli was shown by isolate Bb3F, with the inhibitory zone of 10.80 mm. While
the largest inhibition activity against C.
albicans was shown by isolate Bb1B and Bb3F with the inhibitory zone of
9.70 mm.
