This study aimed to evaluate the safety of raw vegetable products present on German market regarding toxin-producing Bacillus cereus sensu lato (s.l.) group bacteria.A total 147 B. s.l. strains isolated from cucumbers, carrots, herbs, salad leaves and ready-to-eat mixed were analyzed. Their toxinogenic potential was assessed by multiplex PCR targeting hemolysin BL (hbl) component D (hblD), non-hemolytic enterotoxin (nhe) A (nheA), cytotoxin K-2 (cytK-2) cereulide (ces) toxin genes. In...
Pectins are dietary fibers that attributed with several beneficial immunomodulatory effects. Depending on the degree of esterification (DE), pectins can be classified as high methoxyl pectin (HMP) or low (LMP). The aim this study was to investigate effects methyl-esterification intestinal microbiota and its properties in naive mice. Supplementation diet LMP HMP induced changes composition mice toward Bacteroides, which mainly promoted by HMP. Metabolome analysis stool samples from pectin-fed...
The intake of isoflavones is presumed to be associated with health benefits in humans, but also potential adverse effects are controversially discussed. Isoflavones can metabolized by gut bacteria leading modulation the bioactivity, such as estrogenic effects. Especially bacterial strains Eggerthellaceae, a well-known family human microbiota, able convert isoflavone daidzein into equol. In addition, metabolization genistein described for Eggerthellaceae. aim this study was identify and...
Penicillium verrucosum, P. nordicum and Aspergillus carbonarius are three important ochratoxin A producing species. verrucosum is in addition able to produce citrinin. It has been shown earlier that adapted NaCl rich environments like salt dry cured foods or even salines. In this organism, the biosynthesis of plays an adaptive role habitat. generally can be found on cereals, but occasionally also foods. contrast A. usually cannot environments, it occurs another environment with high...
Two novel, anaerobic, Gram-positive, rod-shaped bacterial strains, ResAG-85T and ResAG-96T, were isolated from a faecal sample of male human. 16S rRNA gene sequences analyses indicated that these strains represent distinct lineage within the family Eggerthellaceae. Strain showed 92.3 % similarity to type genera Eggerthella Gordonibacter. ResAG-96T clustered together with Paraeggerthella hongkongensis newly (but not validly) published genus 'Arabia massiliensis' (94.8 similarity). Analysis...
Due to the rising number of type 2 diabetes patients, antidiabetic drug, metformin is currently among those pharmaceuticals with highest consumption rates worldwide. Via sewage-treatment plants, enters surface waters where it frequently detected in low concentrations (µg/L). Since possible adverse effects this substance aquatic organisms have been insufficiently explored date, aim study was investigate impact on health and development brown trout (Salmo trutta f. fario) its microbiome. Brown...
Nanoparticles are ubiquitous in the environment. They originate from anthropogenic or natural sources they intentionally produced for different purposes. There exist manifold applications of nanoparticles modern life leading unavoidably to a confrontation and interaction between nanomaterial living organisms. Based on their wide distribution tending increase steadily, influence particles based silica silver, exhibiting nominal sizes 0.65 nm 200 nm, physiology mycotoxigenic filamentous fungus...
Abstract Background Implants are a predictable and well-established treatment method in dentistry. Nevertheless, looking at possible failures of dental implants, early late loss have to be distinguished. The intent the study was report microbiological findings on surface implants with severe peri-implantitis, which had explanted. Methods 53 specimens from 48 patients without general illnesses been examined. groups investigated were that removed period osseointegration (early loss, 13 14...
A total of 189 samples fresh products (leafy salads, ready-to-eat mixed and herbs) bought in retail Southwest Germany were investigated for their microbiological quality the presence pathogenic bacteria, including Salmonella spp., Listeria monocytogenes, presumptive Bacillus cereus. Total aerobic mesophilic plate counts (TAC) ranged from 5.5 to 9.6 log colony-forming units (CFUs) per gram. Enterobacteria pseudomonads predominant microorganisms detected all with between 5.0 9.2 CFU/g. Strains...
The novel, anaerobic, Gram-positive, rod-shaped bacterial strain, ResAG-91T, was isolated from a faecal sample of male human volunteer. Analysis the 16S rRNA gene sequence revealed that strain ResAG-91T showed high similarity to type strains Adlercreutzia equolifaciens subsp. and celatus. whole draft genome sequences, i.e. digital DNA-DNA hybridization (dDDH) average nucleotide identity (ANI), species represents novel genus Adlercreutzia. size is 2.8 Mbp G+C content 63.3 mol%. major...
Abstract Strain ZW T0_25 T was isolated from an onion sample ( Allium cepa var. Hytech F1) within a storage trial and proofed to be novel, aerobic, Gram-stain negative, rod-shaped bacterial strain. Analyses of the 16S rRNA gene sequence whole draft genome sequences, i.e., digital DNA–DNA hybridization (dDDH), Average Nucleotide Identity (ANI) Amino Acid (AAI) showed that this strain represents new species genus Bosea . The size is 6.19 Mbp, GC content 66.9%. As cell sugars, rhamnose, ribose...
The novel, aerobic, Gram-stain-positive, rod-shaped bacterial strain, ZW T2_19 T , was isolated from an onion sample ( Allium cepa var. Rijnsburger). Analyses of the 16S rRNA gene sequence revealed that represented a member genus Rathayibacter but may represent novel species this genus. whole draft genome sequences, i.e. digital DNA–DNA hybridisation (dDDH) and average nucleotide identity (ANI) all type strains confirmed represents . size is 4.01 Mbp DNA G+C content 71.8 mol%. Glucose,...
Penicillium citrinum is a food-contaminating ascomycete that consistently produces large amounts of the mycotoxin citrinin. Citrinin exhibits, besides its toxicity, antibiotic effects and thus potentially forces resistance. Within genome sequence, we identified biosynthesis gene cluster for citrinin, which appears to be highly conserved within genus Penicillium.
