1. Identification, antibacterial and antifungal effects, antibiotic resistance of some lactic acid bacteria
Abstract A total of 74 lactic acid bacteria (LAB) isolates were obtained from yoghurt, cheese, raw milk, boza and whey. 36 strains were identified at species levels as Lactococcus lactis (15), Lc. garvieae (8) Lactobacillus plantarum (7), Enterococcus faecium (3), Leuconostoc citreum (2) and Lb.casei (1) by MALDI-TOF MS analysis. The strains were tested for

2. Maldi-tof mass spectrometry for the identification and detection of antimicrobial activity of lactic acid bacteria isolated from local cheeses
Abstract In this study, 21 traditionally made cheeses were used. A total of 150 lactic acid bacteria (LAB) isolates were obtained from cheeses. 100 of them were identified at genus levels as Leunoconostoc (10), Lactobacillus (46) and Enterococcus (44) using biochemical tests. 71 strains were identified as Enterococcus durans (6), E. faecalis (18), E. faeciu

3. Microbial characterization and diversity of artisanal Ranchero cheese with emphasis in Lactococcus strains
Abstract The aim of this work is to characterize the natural microflora of artisanal Ranchero cheese and to identify Lactococcus isolates. Ten artisanal Ranchero cheese samples made with raw milk were obtained from local producers located in different geographical areas. Aerobic mesophilic, Staphylococci, Psychrophilic , total coliforms, molds, yeast and, l

4. Effects of heme oxygenase-1 recombinant Lactococcus lactis on the intestinal barrier of hemorrhagic shock rats
This study aimed to investigate the effects of heme oxygenase-1 recombinant Lactococcus lactis (LL-HO-1) on the intestinal barrier of rats with hemorrhagic shock. One hundred Sprague-Dawley male rats (280–320 g) were randomly divided into healthy control group (N group) and hemorrhagic shock group (H group). Each group was subdivided into HO1t, HO2t, HO3t,

5. A functional food: a traditional Tarhana fermentation
Abstract White wheat flour, concentrated full fat yoghurt, tomato paste, onion, red and green paprika, and mint and salt are used in the preparation of Tarhana. During the 7-day Tarhana fermentation period, the acidity increased from 1.10% to 3.25%, the pH decreased from 5.22 to 4.13, and the moisture decreased from 70.12% to 26.15%. The chemical composition

6. Bacteriocinogenic Lactococcus lactis subsp. lactis DF04Mi isolated from goat milk: Application in the control of Listeria monocytogenes in fresh Minas-type goat cheese
Listeria monocytogenes is a pathogen frequently found in dairy products. Its control in fresh cheeses is difficult, due to the psychrotrophic properties and salt tolerance. Bacteriocinogenic lactic acid bacteria (LAB) with proven in vitro antilisterial activity can be an innovative technological approach but their application needs to be evaluated by means o

7. Interação de Saccharomyces cerevisiae e Lactococcus lactis na fermentação e qualidade da cachaça artesanal
Lactococcus lactis e Saccharomyces cerevisiae foram avaliados em co-cultura durante fermentação para a produção de cachaça. L. lactis UFLA CA 312 e S. cerevisiae UFLA CA 11 foram utilizados com populações de aproximadamente 105 CFU mL-1 e 108 UFC mL-1, respectivamente. O meio contendo caldo de cana de açúcar, adicionado de 1% de extrato de levedura

12. Antimicrobial properties of lactic acid bacteria isolated from uruguayan artisan cheese
Uruguayan artisan cheese is elaborated with raw milk and non-commercial starters. The associated native microbiota may include lactic acid bacteria and also potentially pathogenic bacteria. Lactic acid bacteria were isolated from artisan cheese, raw milk, and non-commercial starter cultures, and their potential bacteriocin production was assessed. A culture
