The intestinal microbiota of piglets fed with a Control diet low in dietary fibre and modified wheat bran variants as an additional source of insoluble dietary fibre was characterised. In this context, variances in the microbiota of three different gut segments were assessed. Wheat bran was either included in its native form or modified by fermentation and extrusion before added at 150 g/kg to a basal diet for 48 piglets (12 animals per treatment).

The aim of the present study was to evaluate the influence of native, fermented and extruded wheat bran on the performance and intestinal morphology of piglets. Additionally, short-chain fatty acids (SCFA), biogenic amines, ammonia, lactic acid, pH as well as E. coli and lactic acid bacterial counts were analysed in digesta samples from three gut sections.

Despite its potential health benefits, the integration of wheat bran into the food sector is difficult due to several adverse technological and sensory properties such as bitterness and grittiness. Sourdough fermentation is a promising strategy to improve the sensory quality of bran without inducing severe changes to the bran matrix. Therefore, identification of species/strains with potential for industrial sourdough fermentations is important.

Arabinoxylan is one of the potential key products of a wheat bran based biorefinery. To develop a suitable process for the isolation of arabinoxylans, the effect of different processing approaches needs to be determined. In this work, chemical analysis was supplemented by immunolocalization of arabinoxylan by confocal microscopy, which proved valuable in the assessment of cell-structural changes occurring upon different chemical and mechanical bran treatments.

Introduction: Based on Lactobacillus species co-colonizing the vagina and rectum, it has been hypothesized that the rectum may be an important reservoir for vaginal colonization by lactobacilli. There are no data on this issue in male-to-female transsexual women.

Aim: We undertook this observational study to characterize the Lactobacillus species present in the neovagina and rectum of male-to-female transsexual women and to determine the degree of neovaginal-rectal co-colonization in order to gain a better understanding of the potential role of the gut as a reservoir for genital lactobacilli.

There is a general opinion that penile skin lined neovagina of transsexual women is not able to support the growth of lactobacilli. This study was undertaken to prove if lactobacilli strains could survive in neovagina and to characterise the most dominant Lactobacillus species. Sixty three male-to-female transsexual women without abnormal vaginal discharge, clinical signs of infection were recruited on an ongoing basis from among transsexual outpatients in an academic research institution and tertiary care centre.

Objective: Lactobacilli have been found in the neovagina of very low numbers of transsexual women. We undertook this study to determine whether an orally administered preparation of four lactobacilli strains exerts some measurable effect on the neovaginal microflora of female transsexuals.

Study Design: 60 male to female transsexual women with penile linked neovagina were randomised into two groups.
