PENGENDALIAN SEL BIOFILM BAKTERI PATOGEN OPORTUNISTIK DENGAN PANAS DAN KLORIN
Abstract: Opportunistic pathogenic
bacteria are bacteria
that are naturally
not present in
an environment that,
but it dues to
contamination of the
environment by human
waste. From previous
research it was
found E. coli, Staphylococcus sp.
and Salmonella were
opportunistic pathogens of
the shrimp aquaculture
(Percut, Pantai Labu, Pantai
Cermin). The aims of this study is to know the ability of these bacteria to
form biofilms as well as its control using chlorine and heat. In order to test
the ability of the bacteria to form biofilms, the stainless steel have been
soaked in SWC media for 1, 3, 6 days. E. coli, Salmonella, and Staphylococcus
sp. may form biofilms on incubation of the 1st day but the highest
growth was on the 6th day of incubation by E. coli with a 6,35 x 104 CFU/SS,
whereas of the
lowest biofilm number
was found in
Salmonella with a
0,28 x 104CFU/SS. The
number of biofilm
cells grow in
line with a
length of incubation.
In this research,
the most effective concentration
of chlorine to kill biofilm cell was 225
ppm for 2 minutes and heat was 1000C for 5 minutes. The
higher the concentration
of chlorine and
the temperature given
more effective to
kill the bacteria.
