ABSTRACT Denaturing gradient gel electrophoresis (DGGE) of DNA fragments generated by PCR with 16S ribosomal DNA-targeted group-specific primers was used to detect lactic acid bacteria (LAB) the genera Lactobacillus, Pediococcus, Leuconostoc , and Weissella in human feces. Analysis fecal samples four subjects revealed individual profiles originating not only from species that have been described as intestinal inhabitants but also characteristically food-associated such Lactobacillus sakei,...
ABSTRACT The antibiotic resistances of 45 lactic acid bacteria strains belonging to the genera Lactobacillus , Streptococcus Lactococcus Pediococcus and Leuconostoc were investigated. objective was determine verify these at genetic level, as is currently suggested by European “qualified presumption safety” safety evaluation system for industrial starter strains. In addition, we sought pinpoint possible problems in resistance determinations. Primers used PCR amplify genes involved β-lactam...
Four sourdoughs (A to D) were produced under practical conditions by using a starter mixture of three commercially available sourdough starters and baker's yeast constitutively containing various species lactic acid bacteria (LAB). The continuously propagated until the composition LAB flora remained stable. Two LAB-specific PCR-denaturing gradient gel electrophoresis (DGGE) systems established used monitor development microflora. Depending on prevailing ecological in different fermentations,...
Abstract This paper presents results of a collaborative trial study (IUPAC project No. 650/93/97) involving 29 laboratories in 13 countries applying method for detecting genetically modified organisms (GMOs) food. The is based on using the polymerase chain reaction to determine 35S promoter and NOS terminator detection GMOs. Reference materials were produced that derived from soy beans maize. Correct identification samples containing 2% GMOs achievable both For 0.5% beans, analysis resulted...
ABSTRACT Four sourdoughs (A to D) were produced under practical conditions, using a starter obtained from mixture of three commercially available sourdough starters and baker's yeast. The doughs continuously propagated until the composition microbiota remained stable. A fungi-specific PCR-denaturing gradient gel electrophoresis (DGGE) system was established monitor development yeast biota. analysis revealed presence Candida humilis , Debaryomyces hansenii Saccharomyces cerevisiae uvarum . In...
The working group "Food technology and safety" of the DFG Senate Commission on Food Safety (SKLM) advises new technologies concerning food processing. Treatment with plasma is a newly developed process, which currently used only pilot scale in Europe. novel treatment experimentally applied to consumer goods. There are also potential applications sector, e.g. inactivate microorganisms surfaces. still insufficient information concomitant physical chemical processes changes induced food. On May...
Phenotypic characterization of aggregation phenotypes Lactobacillus coryniformis revealed that strain DSM 20001T coaggregated with Escherichia coli K88, Campylobacter coli, and jejuni but not other human pathogens. In addition, cells these pathogens aggregated in the presence spent culture supernatant (SCS) 20001T. Cells E. K88 remained viable coaggregates aggregates for up to 24 h. Both coaggregation (co/aggregation) occurred at pH 3.5 7.5 was sensitive heat (85 degrees C 15 min) proteinase...
Thirty-two strains originally identified as Lactobacillus acidophilus and L. gasseri were screened for their taxonomic homogeneity by SDS-PAGE of whole-cell proteins. After numerical comparison the resulting protein electrophoretic fingerprints, two well-delineated clusters detected. The majority grouped in one cluster, which contained type strain corresponds to DNA group A1 Johnson, J. L., Phelps, C. F., Cummins, S., London, & Gasser, F. (1980; International Journal Systematic Bacteriology...
Two strains of Acetobacter sp., LTH 2460Tand 2458T, have been isolated from running red wine and cider vinegar fermentations, respectively. Taxonomic characteristics the isolates were investigated. Comparative analysis 16S rRNA sequences revealed < 99% similarity between strain type related species europaeus xylinus 2458Tand pasteurianus. On other hand, low levels DNA relatedness (> 34%) determined in DNA-DNA studies. This below level was consistent with specific physiological permitting...
Aims: To identify structural components of Bacillus subtilis spores serving as targets for sterilization with microwave induced low-pressure, low-temperature nitrogen-oxygen plasma. Methods and Results: The inactivation followed a biphasic kinetics consisting log-linear phase rapid by slow phase. In the course plasma treatment, damage to DNA, proteins spore membranes were observed monitoring occurrence auxotrophic mutants, catalase (KatX) activity leakage dipicolinic acid, respectively....
ABSTRACT Members of the genus Lactobacillus are common inhabitants gut, yet little is known about traits that contribute to their ecological performance in gastrointestinal ecosystems. reuteri 100-23 persists gut reconstituted -free mouse after a single oral inoculation. Recently, three genes this strain were specifically induced (in vivo induced) murine identified (38). We report here detection gene L. encodes high-molecular-mass surface protein (Lsp) shows homology proteins involved...
ABSTRACT Lactobacilli are common inhabitants of the gastrointestinal tracts mammals and have received considerable attention due to their putative health-promoting properties. Little is known about traits that enhance ability these bacteria inhabit tract. In this paper we describe development application a strategy based on in vivo expression technology (IVET) enables detection Lactobacillus reuteri genes specifically induced murine gut. A plasmid-based system was constructed containing ′...
