Acid tolerance of the lactic acid bacterium (LAB) is crucially important for production free as a chemical monomer by simplified purification steps. This study conducts both metabolic modification and adaptive evolution approaches on increasing an engineered Pediococcus acidilactici strain. The overexpression genes encoding lactate dehydrogenase, recombinase, chaperone, glutathione ATPase did n...

The aim of this study was to evaluate the probiotic properties of Pediococcus acidilactici B14 and to study its resistance in the gastrointestinal system when combined with Lactobacillus acidophilus ATCC 4356 and used in a potentially symbiotic aerated soy based dessert. P. acidilactici B14 showed some important probiotic characteristics such as survival rate of 45.9% at pH 2.5; 72.4% in 0.3% b...

This study was oriented to production of bioactive tetradecane reported in extracts Pediococcus acidilactici isolated from curd milk and 16S rRNA sequence analysis isolate showed 98% correlation with P. DSM: 20284-CM (accession no. NR042057.1). activity has been tested by disc diffusion assay against Staphylococcus aureus MRSA ATCC 43300, Listeria monocytogenes 19116, Pseudomonas aeruginosa MTC...

Members of the bacterial population of two types of Portuguese dry smoked sausages (chouriços) were identified and characterized. A total of 77 isolates were recovered from chouriços type Alentejano and Ribatejano, after 120 days at 20 ± 5 oC in modified atmosphere package (55 % N2/45 % CO2) using non-selective and selective media. Based on phenotypic (cell morphology and fermentation profile) ...

BACKGROUND Certain intestinal microflora are thought to regulate the systemic immune response. Lactic acid bacteria are one of the most studied bacteria in terms of their beneficial effects on health and autoimmune diseases; one of which is Multiple sclerosis (MS) which affects the central nervous system. We investigated whether the lactic acid bacterium Pediococcus acidilactici, which comprise...

A total of 84 of 150 vancomycin-resistant (defined as no inhibition of bacterial growth around a 30-micrograms vancomycin disk placed on 5% sheep blood-Trypticase soy agar [BBL Microbiology Systems, Cockeysville, Md.]) bacteria were definitively identified by determining the phenotypic criteria. The identity of representatives was also confirmed by DNA-DNA hybridizations. The following strains ...

Pediococci are homofermentative, gram-positive, nonmotile, catalase-negative facultative anaerobes of the family Streptococcaceae and are used in the biotechnology and food industries (1, 2, 7). The ecologic niche of pediococci in humans appears to be the enteral tract (7). Although pediococci have been described as harmless bacteria (5), they have been infrequently recovered from the human res...

Ninety-two strains of lactic acid bacteria (LAB) were isolated from a Malaysian food ingredient, chili bo, stored for up to 25 days at 28 degreesC with no benzoic acid (product A) or with 7,000 mg of benzoic acid kg-1 (product B). The strains were divided into eight groups by traditional phenotypic tests. A total of 43 strains were selected for comparison of their sodium dodecyl sulfate-polyacr...
