Mozzarella (M), Grana Padano (GP) and Parmigiano Reggiano (PR) are three of the most important traditional Italian cheeses. In cheese manufactures initial fermentation is carried out by adding natural whey cultures (NWCs) according to a back-slopping procedure. this study, NWCs corresponding curds from M, GP PR were analyzed culture-independent pyrosequencing amplified V1-V3 regions 16S rRNA gene, in order provide insights into microbiota involved curd acidification. Moreover,...
<h3>Objectives</h3> Habitual diet plays a major role in shaping the composition of gut microbiota, and also determines repertoire microbial metabolites that can influence host. The typical Western corresponds to an omnivore; however, Mediterranean (MD), common culture, is date nutritionally recommended dietary pattern includes high-level consumption cereals, fruit, vegetables legumes. To investigate potential benefits MD this cross-sectional survey, we assessed microbiota metabolome cohort...
Objectives This study aimed to explore the effects of an isocaloric Mediterranean diet (MD) intervention on metabolic health, gut microbiome and systemic metabolome in subjects with lifestyle risk factors for disease. Design Eighty-two healthy overweight obese a habitually low intake fruit vegetables sedentary participated parallel 8-week randomised controlled trial. Forty-three participants consumed MD tailored their habitual energy intakes (MedD), 39 maintained regular diets (ConD)....
Prevotella copri is a common human gut microbe that has been both positively and negatively associated with host health. In cross-continent meta-analysis exploiting >6,500 metagenomes, we obtained >1,000 genomes explored the genetic population structure of P. copri. encompasses four distinct clades (>10% inter-clade divergence) propose constitute complex, all were confirmed by isolate sequencing. These are nearly ubiquitous co-present in non-Westernized populations. Genomic analysis showed...
We present a global atlas of 4,728 metagenomic samples from mass-transit systems in 60 cities over 3 years, representing the first systematic, worldwide catalog urban microbial ecosystem. This provides an annotated, geospatial profile strains, functional characteristics, antimicrobial resistance (AMR) markers, and genetic elements, including 10,928 viruses, 1,302 bacteria, 2 archaea, 838,532 CRISPR arrays not found reference databases. identified 4,246 known species microorganisms consistent...
The larva of the black soldier fly (Hermetia illucens) has emerged as an efficient system for bioconversion organic waste. Although many research efforts are devoted to optimization rearing conditions increase yield process, microbiological aspects related this insect still neglected. Here, we describe microbiota midgut H. illucens larvae, showing effect different diets and regions in shaping microbial load diversity. bacterial communities residing three parts midgut, characterized by...
Abstract Traditional cheeses harbour complex microbial consortia that play an important role in shaping typical sensorial properties. However, the metabolism is considered difficult to control. Microbial community succession and related gene expression were analysed during ripening of a traditional Italian cheese, identifying parameters could be modified accelerate ripening. Afterwards, we modulated conditions observed consistent changes structure function. We provide concrete evidence...
Although disinfection is key to infection control, the colonization patterns and resistomes of hospital-environment microbes remain underexplored. We report first extensive genomic characterization microbiomes, pathogens antibiotic resistance cassettes in a tertiary-care hospital, from repeated sampling (up 1.5 years apart) 179 sites associated with 45 beds. Deep shotgun metagenomics unveiled distinct ecological niches genes characterized by biofilm-forming human-microbiome-influenced...
Abstract Gut microbes programme their metabolism to suit intestinal conditions and convert dietary components into a panel of small molecules that ultimately affect host physiology. To unveil what is behind the effects key on microbial functions way they modulate host–microbe interaction, we used for first time multi-omic approach goes mere gut phylogenetic composition provides an overall picture functional repertoire in 27 fecal samples from omnivorous, vegan vegetarian volunteers. Based...
Abstract Understanding the functional potential of gut microbiome is primary importance for design innovative strategies allergy treatment and prevention. Here we report features 90 children affected by food (FA) or respiratory (RA) allergies 30 age-matched, healthy controls (CT). We identify specific microbial signatures in allergic children, such as higher abundance Ruminococcus gnavus Faecalibacterium prausnitzii , a depletion Bifidobacterium longum Bacteroides dorei B. vulgatu s...
Microbial growth on meat to unacceptable levels contributes significantly change structure, color and flavor cause spoilage. The types of microorganisms initially present in depend several factors multiple sources contamination can be identified. aims this study were evaluate the microbial diversity beefsteaks before after aerobic storage at 4°C investigate by examining microbiota carcasses wherefrom steaks originated processing environment where beef was handled. Carcass, environmental...
The bacterial ecology during rye and wheat sourdough preparation was described by 16S rRNA gene pyrosequencing. Viable plate counts of presumptive lactic acid bacteria, the ratio between bacteria yeasts, rate acidification, a permutation analysis based on biochemical microbial features, number operational taxonomic units (OTUs), diversity indices all together demonstrated maturity sourdoughs 5 to 7 days propagation. Flours were mainly contaminated metabolically active genera (Acinetobacter,...
Intermediates of production two batches traditional mozzarella cheese were analyzed by culture-independent pyrosequencing. The quantitative distribution taxa within the samples suggested that thermophilic lactic acid bacteria from natural starter mainly responsible for fermentation, while microorganisms found in raw milk did not develop during fermentation.
ABSTRACT Microbial contamination in food processing plants can play a fundamental role quality and safety. The aims of this study were to learn more about the possible influence meat environment on initial fresh investigate differences between small-scale retail distribution (SD) large-scale (LD) facilities. Samples collected from butcheries ( n = 20), including LD 10) SD facilities, over two sampling campaigns. included beef pork cuts swab samples knife, chopping board, butcher's hand....
