Lactobacillus plantarum 423 produces a small heat-stable antimicrobial protein designated plantaricin 423. This protein is bactericidal for many Gram-positive foodborne pathogens and spoilage bacteria, including Listeria spp., Staphylococcus spp., Pediococcus spp., Lactobacillus spp., etc. The DNA sequence of the plantaricin 423-encoding region on plasmid pPLA4 revealed a four open reading fram...

Beef jerky has been linked to multiple outbreaks of salmonellosis and Escherichia coli O157:H7 infection over the past 40 years. With increasing government scrutiny of jerky-making process lethality, a simple method by which processors can easily validate the lethality of their ground-and-formed beef jerky process against Salmonella' and E. coli O157:H7 is greatly needed. Previous research with...

A realistic description of the variability in bacterial growth and division is critical to produce reliable predictions of safety risks along the food chain. Individual-based modeling of bacteria provides the theoretical framework to deal with this variability, but it requires information about the individual behavior of bacteria inside populations. In this work, we overcome this problem by est...

BACKGROUND The present study aimed to determine the inhibitory activity of postbiotic produced by L. plantarum using reconstituted media supplemented with different levels of inulin and to select the best combination based on the modified inhibitory activity (MAU/mL) against pathogens. METHODS Postbiotics were produced by 6 strains of L. plantarum (RG11, RG14, RI11, UL4, TL1 and RS5) using re...

In this study we evaluated the effects of the probiotic Pediococcus acidilactici MA18/5M on shrimp, Litopenaeus stylirostris (also called Penaeus stylirostris), first on antioxidant defences and secondly on the oxidative stress status in the shrimps' haemolymph and digestive gland. We conducted two experiments with the same protocol in which shrimps were fed two diets for three weeks: a control...

Background and Aim: Probiotics are beneficial microorganisms for humans animals. In this study, we developed a microencapsulated probiotic with antibacterial activity against avian pathogenic Escherichia coli (APEC). Materials Methods: Alignment of the 16S rRNA sequences isolate WU222001 those deposited in GenBank revealed that was Pediococcus acidilactici 99.6% homology. This bacterium charact...

Penggunaan probiotik merupakan salah satu strategi untuk mengatasi permasalahan yang ada pada budidaya perikanan. Penerapan probiotik, yakni mikroorganisme menguntungkan mampu mendegradasi bahan organik, mereduksi penyakit, dan membantu mempercepat proses siklus nutrien sebagai konsekuensi dari udang super intensif. Penelitian ini bertujuan mengevaluasi pengaruh penambahan Probiotik kombinasi B...

This study aimed to determine the antibiotic and bacteriocin sensitivity of Listeria monocytogenes strains isolated from animal derived foods. With disc diffusion assay, all fourteen L. monocytogenes strains were susceptible to the antibiotics, including penicillin G, vancomycin, tetracycline, chloramphenicol, rifampicin, erythromycin, gentamicin and trimethoprim. However, the percentage...

Indonesia has many kind of fermented foods such as tempe, fermented rice, fermented cassava, and fermented vegetable. Lactic acid bacteria that can produce β glycosidase most likely in the fermented foods from plants materials. The objectives of the research were to isolate lactic acid bacteria producing β glucosidase enzyme from Indonesian fermented foods and identify the isolates to their spe...
