Abstract :
DAYA HAMBAT SUSU FERMENTASI ?C? TERHADAP PERTUMBUHAN
BAKTERI Escherichia coli PADA BERBAGAI KONSENTRASI
Saat ini produksi makanan pangan fungsional sudah banyak berkembang.
Susu fermentasi, salah satu pangan fungsional yang saat ini semakin
berkembang dikenal memiliki manfaat bagi kesehatan tubuh karena adanya
aktivitas anti-mikroba yang dapat mengurangi infeksi gastrointestinal.
Bakteri yang terdapat dalam susu fermentasi merupakan kelompok bakteri
asam laktat yang terdiri dari Streptococcus thermophilus dan Lactobacillus
delbrueckii subsp. bulgaricus. Penelitian ini bertujuan untuk mengetahui
daya hambat susu fermentasi ?C? terhadap pertumbuhan bakteri
Escherichia coli dengan konsentrasi 10%, 40%, 70%, 100% dan kontrol (+)
Antibiotik Ceftazidime. Uji antibakteri dilakukan dengan menggunakan
metode Kirby-Bauer disk diffusion method pada media agar Mueller Hinton.
Pada penelitian ini didapatkan bahwa Susu fermentasi tidak terbukti efektif
dalam menghambat pertumbuhan bakteri Escherichia coli.

BACTERIA Escherichia coli AT VARIOUS CONCENTRATIONS
Nowadays, the production of functional food is growing. Fermented
milk, one of the more developed functional food is known to have
benefits for the health of the body due to the presence of anti-microbial
activity that can reduce gastrointestinal infections. The bacteria
contained in fermented milk is a group of lactic acid bacteria consisting
of Streptococcus thermophilus and Lactobacillus delbrueckii subsp.
bulgaricus. This research aims to know the resistance of fermented milk
"C" to the growth of Escherichia coli bacteria with a concentration of
10%, 40%, 70%, 100% and control (+) of Ceftazidime antibiotics.
Antibacterial tests were carried out using the Kirby-Bauer disk
diffusion method on the media for Mueller Hinton Agar. In this
research, it is found that fermented milk is not proven to be effective in
inhibiting the growth of Escherichia coli bacteria.
