Bakteri Coliform dalam Es Batu pada Tiga Rumah Makan Ayam Goreng Siap Saji di Bandung
Abstract: Some reports have
shown that ice cubes may contain Enterobacteriaceae bacteria. This descriptive,
observational research aims to analyze the microbiological quality of the ice
cubes served at three selected restaurants
(1,2,3). Three samples
of ice cubes
were rinsed with
steril water, left
melted, and diluted serially. Each
diluted sample was
inoculated into MacConkey
Agar and EMB
Agar with pour
plate method duplo. The data collected were the number of
colonies (interpreted as cfu or colony forming
unit) of Escherichia coli and other Enterobacteriaceae bacteria. The
species of selected colonies were identified by biochemical reactions. The
result showed that sample 1 contained 3 cfu/ml Escherichia coli and 5 cfu/ml Pseudomonas sp.
Sample 2 contained
10 cfu/ml Escherichia
coli and 4
cfu/ml Pseudomonas sp.,
but sample 3 didn’t contain Escherichia coli and other
Enterobacteriaceae bacteria members. It is concluded that ice cubes from
restaurant 3 met the requirement for drinking water, whereas those from restaurants 1 and 2 did not.
