The aim of this study is to evaluate the microbiome characteristics of adult type 1 SBS-CIF patients according to their clinical features.

Spotlight on autochthonous microbiota, morpho-textural characteristics, and volatilome of a traditional Polish cold-smoked raw sausage.

The aim of the present study was to obtain information on the bacterial diversity of traditional Polish cold-smoked raw sausages (Kiełbasa polska wędzona) manufactured by two artisanal producers using different selective growth media and a metataxonomic analysis. Physico-chemical and morpho-textural characteristics were also carried out, together with Microextraction-Gas Chromatography/Mass Spectrometry (HS-SPMEGC/MS) to study the volatile organic compounds (VOCs). The results overall obtained allowed a picture of the microbiota, the morpho-textural characteristics, and the volatilome of traditional Polish cold-smoked raw sausages (Kiełbasa polska wędzona) to be drawn for the first time.

Chemical, microbiological, textural, and sensory characteristics of pilot-scale Caciofiore cheese curdled with commercial Cynara cardunculus rennet and crude extracts from spontaneous and cultivated Onopordum tauricum.

The aim of this study was the chemical, microbiological, textural, and sensory characterization of pilot-scale prototypes of an Italian ewe's raw milk cheese (Caciofiore) curdled with commercial Cynara cardunculus rennet, used as a control, and crude extracts obtained from flowers of either spontaneous or cultivated Onopordum tauricum. Hence, the control and experimental cheese prototypes produced in two rounds of cheesemaking trials were assayed, at the end of their 60-day maturation, for the following features: pH, titratable acidity, dry matter, fat, total and soluble nitrogen (TN and SN, respectively), ash, salt, protein, lactose, viable plate counts and composition of the bacterial and fungal populations, color, texture, volatile organic compounds (VOCs), and olfactory attributes by sensory analysis (the latter for the sole prototypes curdled with the commercial rennet and the extract obtained from cultivated O. tauricum).

PDO Cheese: Investigation into Its Morpho-Textural Traits, Microbiota, and Volatilome.

Queijo Serra da Estrela is a PDO Portuguese cheese produced through coagulation of raw ewe’s milk using cardoon (Cynara cardunculus L.) flowers. The present research was aimed at depicting an up-to-date and comprehensive overview of the microbiota of Queijo Serra da Estrela cheese.

Autochthonous starter culture selection for Salame Piemonte PGI production.

Salame Piemonte is a dry-fermented meat product typical of the Piedmont region in Italy, manufactured using commercial starter cultures. This study aimed to select autochthonous starter cultures (ASCs) that could be used for sausage fermentation in order to strengthen the link with the geographical area of production and improve the sensory properties of the final product. A culture-dependent approach was adopted during three different spontaneous sausage fermentation processes to isolate and characterise the main bacterial resources involved.

Microbiological, morpho-textural, and volatile characterization of Portuguese Queijo de Nisa PDO cheese.

Queijo de Nisa PDO (Protected Designation of Origin) is a semi-hard cheese obtained from raw ewe's milk clotted with cardoon (Cynara cardunculus, L.) rennet. The aim of the present study was to characterize the bacterial communities naturally occurring in Queijo de Nisa PDO cheese samples through viable counting and metataxonomic analysis.

Croatian white grape variety Maraština: First taste of its indigenous mycobiota.

The indigenous vineyard mycobiota contribute both to wine quality and vineyard sanitary status. Wines made from same grape variety but from different geographical locations are appreciated for their diversity. Because no information on indigenous mycobiota of Croatian grapevines is available, the aim of the present study was to start filling this knowledge gap by characterizing the indigenous mycobiota of Maraština variety.

Microbial diversity, morpho-textural characterization, and volatilome profile of the Portuguese thistle-curdled cheese Queijo da Beira Baixa PDO.

The aim of the present study was to characterize the bacterial and fungal communities naturally occurring in Queijo da Beira Baixa PDO cheese samples produced in Castelo Branco district (Beira Baixa Region, Portugal) through viable counts and metataxonomic analyses. Physico-chemical and morpho-textural analyses were also carried out, together with the analysis of volatile organic compounds (VOCs). In the analyzed samples, pH values ranged between 4.

Fate of Escherichia coli artificially inoculated in Tenebrio molitor L. larvae rearing chain for human consumption.

The edible insect food chain represents a relatively novel food-producing system; hence, associated biological risks still need to be exhaustively evaluated. In the present study, the dynamics of Escherichia coli during the whole living period of Tenebrio molitor larvae (from eggs to pupae) were studied. To this end, a rearing substrate consisting of organic wheat middlings was spiked with E.

Mycobiota composition and changes across pregnancy in patients with gestational diabetes mellitus (GDM).

The gut mycobiota has never been studied either during pregnancy or in patients with gestational diabetes (GDM). This study aimed to analyze the fecal mycobiota of GDM patients during the second (T2) and third (T3) trimester of pregnancy and to compare it with the mycobiota of pregnant normoglycemic women (controls). Forty-one GDM patients and 121 normoglycemic women were studied.

Metataxonomic signature of beef burger perishability depends on the meat origin prior grinding.

Spoilage dynamics of two beef burger batches from different beef origins were followed from their shared processing run until the use-by date and beyond. Amplicon based sequencing of bacterial and fungal communities were compared with microbial counts and volatilome profile in order to determine whether and at which extent their perishability was related to the batch origin. Microbiological counts did not differ between batch A and B, whereas Volatile Organic Compounds (VOCs) profiles were only distinguishable after the use-by date.

Technological, functional and safety properties of lactobacilli isolates from soft wheat sourdough and their potential use as antimould cultures.

Bakery products are a common medium for fungal growth due to their high-water activity and nutrients availability. The application of lactic acid bacteria (LAB) isolated from wheat bran or other cereals has shown great potential in controlling the growth of spoilage fungi, guarantee quality and prolong the shelf life of bakery products. This study outlines the antifungal, technological, functional and safety properties of autochthonous LAB microbiota isolated from type 0 soft wheat sourdough fermentation.

Specific metagenomic asset drives the spontaneous fermentation of Italian sausages.

Metagenomics is a powerful tool to study and understand the microbial dynamics that occur during food fermentation and allows to close the link between microbial diversity and final sensory characteristics. Each food matrix can be colonized by different microbes, but also by different strains of the same species. In this study, using an innovative integrated approach combining culture-dependent method with a shotgun sequencing, we were able to show how strain-level biodiversity could influence the quality characteristics of the final product.

Sausage fermentation and starter cultures in the era of molecular biology methods.

Fermented sausages have a long tradition originating from Europe and they constitute a significant part of the Mediterranean diet. This kind of products has a specific microbiota that is typical of the region or area where they are produced. Therefore, in order to protect the traditional aspect of these products, it is essential to understand the microbial ecology during fermentation by studying the dynamic changes that occur and to select autochthonous starter cultures that can be used in the production.
