Lactic acid bacteria (LAB) were isolated from camel milk by culturing the milk on specific media and pure culture was obtained by sub-culturing. Purification of culture was confirmed by Gram’s staining and identified by different biochemical tests. Camel milk contained lactic acid producing bacteria like Streptococci such as S. cremoris and S. lactis and Lactobacilli such as L. acidophilus. L. ...

the harmful effects of many chemical food preservatives are well established, so this has triggered interest in natural methods of preservation. monolaurin, a monoester of lauric acid, founds naturally in some foods and has various antiviral and antibacterial activities. evaluation of the effects of monolaurin separately and in combination with lactic acid bacteria (lab) starter culture on grow...

This paper focuses on the functional properties of maize sour-dough microflora selected and tested for their use as starter cultures for sour maize bread. Lactic acid bacteria and yeasts isolated from spontaneously fermented maize dough were selected based on dominance during fermentation and presence at the end of fermentation. Functional properties examined included acidification, leavening a...

In investigations on slow acid development by lactic acid starter cultures,2 only limited consideration has been given to the effect of other bacteria present in the raw milk. Attention has been directed to inhibitory effects of such substances as nisin produced by certain streptococci and to possible inhibition by other bacteria (Cox and Whitehead, 1931; Babel, 1955). However, little specific ...

Bacteria used to ferment milk to obtain yogurt belong to thermophilic, bile-sensitive species of lactic acid bacteria, which are not ideally suited for survival into the human gut. However, assessing the viability of these bacteria through the digestive tract may be relevant to evaluate their potential to deliver some beneficial effects for the well-being of the consumer. The well-known reducti...

The profile of polyunsaturated fatty acids in cheeses obtained through fermentation by lactic acid bacteria Lactobacillus helveticus and Streptococcus thermophilus were evaluated. milk used to make the came from cows fed with flaxseed oil annato. presented microbiological physic-chemical quality standards established legislation for Staphylococci Listeria. With maturation, there was a reduction...

Milk kefir grains (KGs) are composed of a complex symbiotic microbial mixture of bacteria and yeasts growing in kefiran, an extracellular polysaccharide substance of bacterial origin. This is the first report documenting a successful attempt at reforming KGs using pure mixed starter-cultures of microorganisms isolated from KGs, and gain insight into an otherwise hidden world. A milk pouch syste...

Since cheese is poor in energy for bacterial growth, it believed that non-starter lactic acid bacteria growth and flavour development are supported by the nutrients from lysis of starter culture. This study was performed to investigate dynamics interaction between strains cheese. A culture lysate prepared enzymatic digestion tested as a substrate Lactobacillus sp. strains. The two Lactococcus l...

Immunomodulatory properties of 10 dairy propionibacteria, analyzed on human peripheral blood mononuclear cells (PBMCs), revealed a highly strain-dependent induction of anti-inflammatory cytokine interleukin 10 (IL-10). Two selected strains of Propionibacterium freudenreichii showed a protective effect against two models of colitis in mice, suggesting a probiotic potential predicted by immune-ba...
