| dc.description.abstract | Rebon shrimp paste is a fermented product with raw materials of rebon
shrimp with salt which is generally done in Indonesia. The active compound
produced by lactic acid bacteria is called bacteriocin. Bacteriocins are active
compounds produced by bacteria including lactic acid bacteria that function as
bactericides. Traditionally made rebon shrimp paste products have different
bacteria and characteristics. The objectives of this study are as follows, to
determine the type of lactic acid bacteria isolated from shrimp paste (Acetes
indicus) produced from Gebang District, Langkat Regency. To determine the
inhibitory power of LAB isolates isolated from shrimp paste (Acetes indicus)
from Gebang District, Langkat Regency against pathogenic bacteria.
Research procedures are sampling techniques, sample preparation
techniques, isolation of lactic acid bacteria, morphological characterization of
lactic acid bacteria, gram staining, observation of LAB morphological characters,
physiological characterization of LAB, catalase test, triple sugar iron agar (TSIA)
test, Motility test, identification of Lactic Acid Bacteria, Antagonistic Inhibitory
Test of LAB Isolates against Pathogenic Bacteria Isolation of LAB from 3
processing shrimp paste located in Gebang District, Langkat Regency with the
aim of growing LAB colonies on MRSA media with the addition of 1% CaCO3.
Lactic acid bacteria isolation was carried out using the pour cup method for 3
repetitions and then incubated at 37oC for 2 days. Based on the observation of
LAB isolation grown on MRSA media presented. The results of bacteria from the
isolation of shrimp paste rebon from Gebang District, Langkat Regency, types of
lactic acid bacteria with the genus are Bacillus sp., Streptococcus sp.,
Lactobacillus sp., Brevibacterium sp., Micrococcus sp. and Corynebacterium sp.
The results of the inhibition of LAB isolates from shrimp paste rebon (Acetes
indicus) from Gebang District, Langkat Regency against Eschericia coli and
salmonella in the Terasi Processing Unit are all three categorized as strong | en_US |
