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. The effects of kefir grain and starter culture on kefir produced from cow and buffalo milk during storage periods
Abstract The present study was aimed to determine the effect of different types of milk and kefir grains or starter cultures on the chemical properties, and microorganism counts of kefir samples. The type of milk had a significant effect on the acidity, dry matter, protein, and CO2 values. Acidity and CO2 values increased during storage period, while dry mat

3. Pseudomonas spp. and other psychrotrophic microorganisms in inspected and non-inspected Brazilian Minas Frescal cheese: proteolytic, lipolytic and AprX production potential
RESUMO: O mais consumido no Brasil, o queijo Minas Frescal (QMF) é altamente suscetível à contaminação microbiana e a produção e comercialização clandestina podem representar um risco para a saúde do consumidor. O armazenamento deste produto fresco sob refrigeração, embora mais apropriado, pode favorecer a multiplicação de bactérias psicrotró

5. 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

6. 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

7. 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

8. EFFECTS OF DIETARY FERMENTED GARLIC ON THE GROWTH PERFORMANCE, RELATIVE ORGAN WEIGHTS, INTESTINAL MORPHOLOGY, CECAL MICROFLORA AND SERUM CHARACTERISTICS OF BROILER CHICKENS
ABSTRACT The present study was conducted to evaluate the effects of feeding broilers with garlic fermented by Leuconostoc citreum SK2556. A total of 250 male broiler chicks was randomly housed into 25 floor pens. Five dietary treatments with five replicates of 10 chicks each (n=50 chicks/treatment). A corn and soybean meal based diet was used as the control

9. Bacaba beverage produced by Umutina Brazilian Amerindians: Microbiological and chemical characterization
Bacaba chicha is a beverage prepared by the indigenous Umutina people from the bacaba fruit (Oenocarpus bacaba), a purple berry that is rich in fat and carbohydrates, as well as a source of phenolic compounds. In this study, samples of bacaba chicha beverage were collected, and the microbial community was assessed using culture-dependent and -independent tec

10. Characterization of the spoilage lactic acid bacteria in “sliced vacuum-packed cooked ham”
The lactic acid bacteria are involved with food fermentation and in such cases with food spoilage. Considering the need to reduce the lactic acid bacteria growth in meat products, the aim of this work was to enumerated and investigated the lactic acid bacteria present on sliced vacuum-packed cooked ham stored at 4 °C and 8 °C for 45 days by phenotypic and

11. Cultivable endophytic bacteria from leaf bases of Agave tequilana and their role as plant growth promoters
Agave tequilana Weber var. 'Azul' is grown for the production of tequila, inulin and syrup. Diverse bacteria inhabit plant tissues and play a crucial role for plant health and growth. In this study culturable endophytic bacteria were extracted from leaf bases of 100 healthy Agave tequilana plants. In plant tissue bacteria occurred at mean population densitie

12. Characterization of Bacteriocin like inhibitory substance produced by a new Strain Brevibacillus borstelensis AG1 Isolated from 'Marcha'
In the present study, a bacterium isolated from Marcha- a herbal cake used as traditional starter culture to ferment local wine in North East India, was evaluated for bacteriocin like inhibitory substance production and was tested against six food borne/spoilage causing pathogens viz. Listeria monocytogenes MTCC 839, Bacillus subtilis MTCC 121, Clostridium p
