Abstract

Typhoid fever is an infection of the digestive tract caused by Salmonella typhi bacteria. One of the Lactic Acid Bacteria (LAB) in the digestive tract is Lactobacillus acidophilus which has bacteriocins to protect the digestive tract. Bacteriocin is an antimicrobial protein compound that is bactericidal or bacteriostatic. Bacteriocin protein have an optimum temperature range to provide antimicrobial effect. The aimed of this study was determine the temperature optimization of L.acidophilus bacteriocins on S.typhi growth by agar diffusion method. In this research, the extraction of L.acidophilus ATCC 4356 bacteriocin were treated with a temperature of 40o, 60o, 80o, 100o, and 121oC. The results of research observations were carried out by measuring the diameter of the inhibition zone in each treatment. The result temperature optimization test for L.acidophilus bacteriocins did not give positive inhibition zone. This is due to several reasons, namely the storage and McFarland 0.5 standard setting is too small to inhibit S.typhi growth. This is evidenced by the preliminary test without McFarland arrangement which can provide 3mm diameter inhibition. Therefore, further research is needed related to the use of the Mcfarland standard and its bacteriocin storage.
