Abstract

Abstract Probiotics are live microorganisms which when consumed in large number together with a food promote the health of the consumer. The aim of this study was to evaluate in vitro probiotic properties of lactic acid bacteria (LAB) isolated from traditional Ethiopian fermented Teff injera dough, Ergo and Kocho products. A total of 90 LAB were isolated, of which 4 (4.44%) isolates showed 45.35-97.11% and 38.40-90.49% survival rate at pH values (2, 2.5 and 3) for 3 and 6 h in that order. The four acid tolerant isolates were found tolerant to 0.3% bile salt for 24 h with 91.37 to 97.22% rate of survival. The acid-and-bile salt tolerant LAB isolates were found inhibiting some foodborne test pathogenic bacteria to varying degrees. All acid-and-bile tolerant isolates displayed varying sensitivity to different antibiotics. The in vitro adherence to stainless steel plates of the 4 screened probiotic LAB isolates were ranged from 32.75 to 36.30% adhesion rate. The four efficient probiotic LAB isolates that belonged to Lactobacillus species were identified to strain level using 16S rDNA gene sequence comparisons and namely were Lactobacillus plantarum strain CIP 103151, Lactobacillus paracasei subsp. tolerans strain NBRC 15906, Lactobacillus paracasei strain NBRC 15889 and Lactobacillus plantarum strain JCM 1149. The four Lactobacillus strains were found to have potentially useful to produce probiotic products.

  • Species of Lactobacillus and Bifidobacterium are most commonly used as probiotics because they play an important role in maintaining proper intestinal function and stimulating the host immune system.

    “Species belonging to the genera Lactobacillus and Bifidobacterium are most commonly used as probiotics because they play a very important role in maintaining proper intestinal function and stimulating the host immune system [212,221,222].”

    From Lactic Acid Bacteria in Raw-Milk Cheeses: From Starter Cultures to Probiotic Functions (2022) · cites this paper as [221]

    The Introduction (page not available) identifies Lactobacillus and Bifidobacteria among the most common probiotic types and says probiotic microbes may enhance immune responses. It does not specifically say they maintain proper intestinal function or establish those benefits as the reason the genera are most commonly used. (LLM, conf=0.84)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
