AKTIVITAS ANTIMIKROBA Lactobacillus plantarum 1 YANG DIISOLASI DARI INDUSTRI PENGOLAHAN PATI SAGU TERHADAP BAKTERI PATOGEN Escherichia coli FNCC-19 DAN Staphylococcus aureus FNCC-15
Abstract: The purpose of this
study was todetermined and measure the antimicrobial activity of Lactobacillus
plantarum 1 isolated from sago starch processing industry against pathogenic
bacteria Escherichia coli FNCC-15 and Staphylococcus aureusFNCC-19. The
research was carried out experimentally
using Completely RandomizedDesign (CRD) with four as treatments and four
replications. Antimicrobial activity was tested using the well diffusion method
and the paper disc diffusion method. Result of analysis of variance showed that
the antimicrobial activity of lactic acid bacteria isolates and cell-free
supernatant of bacteriaStaphylococcus aureus FNCC-15 and Escherichia coli
FNCC-19 were significantly different (P<0.05%). T test result showed that the inhibition zone
produced acid between bacteria isolates to cell-free supernatant were
significantly different (P<0.05%).The average diameter inhibition zone of
lactic acid bacteria isolated againstStaphylococcus aureus FNCC-15 were from
6.10 to 8.08 mm. The average diameter inhibition zone of lactic acid bacteria
isolated againstEscherichia coli FNCC-19 were from 6.80 to 9.20 mm. The average
diameter cell-free supernatant inhibition zone against bacteria Staphylococcus
aureus FNCC-15 were from 1.22 to 2.41 mm and inhibition cell-free supernatant
against Escherichia coli FNCC-19 ranged from 2.06 to 3.50 mm. The results of
this study indicate that the isolates of Lactobacillus plantarum 1 RN2-12112
and the supernatant had greater antimicrobial activity than isolates of
Lactobacillus plantarum 1RN2-53.
