The growth and viability of three Lactobacillus strains, Lactobacillus acidophilus, Lactobacillus plantarum and Lactobacillus rhamnosus, after their passage through simulated gastric and pancreatic juices were studied as a function of their presence in the growth medium of rocket salad (Eruca sativa). The presence of E. sativa affected some of the biological properties of the strains. For examp...
Introduction: Probiotics are defined as live non-pathogenic microorganisms and if administered in adequate amounts, can have beneficial effects on their hosts. This study aimed to isolate Gram-positive bacteria from different sources and to evaluate their probiotic properties. Methods: We obtained five samples from various sources including yogurt, infant feces, cheese, and soil under aseptic m...
periodically, marine bacteria are producer of secondary metabolites in the harsh ocean. In this present study, a marine bacterium was isolated from marine cone snail in the Gulf of Mannar. The potential isolates was tested for various biochemical test and 16Sr RNA gene sequencing, which leads to their identification as Bacillus megaterium producing antibiotic compound for treating human disease...
background: the aim of this in vitro study was to assess antimicrobial efficacy of acacia nilotica, murraya koenigii (l.) sprengel, eucalyptus hybrid , psidium guajava extracts, and their combination on streptococcus mutans and lactobacillus acidophilus. materials and methods: the branches of four plants were collected, identified, and authenticated by a taxonomist. the plants were rinsed in wa...
The aim of this paper is to determine the modulatory effects of Lactobacillus acidophilus on the IL-23/Th17 immune axis in experimental colitis. DSS-induced mouse models of UC were to be saline, hormones, and different concentrations of Lactobacillus acidophilus intervention. The expression of interleukin- (IL-) 17, tumor necrosis factor α (TNFα), IL-23, transforming growth factor β1 (TGFβ1), s...
BACKGROUND & OBJECTIVES Clostridium difficile-associated disease (CDAD) remains an important nosocomial ailment. Antimicrobial therapy used for CDAD gives inconsistent results. This experimental study was planned to investigate the beneficial effects of Lactobacillus acidophilus and epidermal growth factor (EGF) for CDAD management. METHODS Among 10 groups of BALB/c mice (6 in each), group 1 ...
Exopolysacharides (EPS) produced by Lactobacillus acidophilus play an important role in food processing with its well-recognized antioxidant activity. In this study, a L. acidophilus mutant strain with high-yielding EPS (2.92±0.05 g/L) was screened by chemical mutation (0.2 % diethyl sulfate). Plackett-Burman (PB) design and response surface methodology (RSM) were applied to optimize the EPS fe...
Microarray analysis of the genome of Lactobacillus acidophilus identified a number of operons that were differentially expressed in response to carbohydrate source or constitutively expressed regardless of carbohydrate source. These included operons implicated in the transport and catabolism of fructooligosaccharides (FOS), lactose (lac), trehalose (tre) and genes directing glycolysis. Analysis...
BACKGROUND Constipation is a frequent complaint and the combination of a prebiotic and probiotics could have a potentially synergic effect on the intestinal transit. The present study therefore aims to investigate the combination of polydextrose (Litesse), L. acidophilus NCFM® and B. lactis HN019 in a yogurt on intestinal transit in subjects who suffer from constipation. METHODS Patients with...
The aim of the study was to evaluate antibacterial activity of composite materials modified with calcium fluoride against cariogenic bacteria S. mutans and L. acidophilus. One commercially available conventional light-curing composite material containing fluoride ions (F2) and two commercially available flowable light-curing composite materials (Flow Art and X-Flow) modified with 1.5, 2.5, and ...
