This paper focuses on biofilms of Lactobacillus spp. - a type of normal flora isolated from healthy human vaginas of women of childbearing age; thereupon, it broadens the research scope of investigation of vaginal normal flora. The static slide culture method was adopted to foster biofilms, marked by specific fluorescence staining. Laser scanning confocal and scanning electron microscopy were used to observe the microstructure of the biofilms. Photographs taken from the microstructure were analysed to calculate the density of the biofilms. The body of Lactobacillus spp., though red, turned yellow when interacting with the green extracellular polysaccharides. The structure of the biofilm and aquaporin within the biofilm were imaged. Lactobacillus density increases over time. This study provides convincing evidence that Lactobacillus can form biofilms and grow over time in vitro. This finding establishes an important and necessary condition for selecting proper strains for the pharmaceutics of vaginal ecology.

Microencapsulated phenolic compounds from organic coffee husk: Impacts on human gut microbiota and in vitro prebiotic potential.

This research investigated the influence of the microencapsulation of phenolic compounds (PCs) from organic coffee husk with whey protein concentrate (WPC) and maltodextrin on the abundance of intestinal bacterial populations and their metabolic activity during in vitro fecal fermentation. The microencapsulated PCs were gradually metabolized during fecal fermentation, resulting in significant transformations and an increase in PCs in the fermentation media. The metabolism of PCs by the fecal microbiota occurred concurrently with the consumption of sugars, production of organic acids, and reduction in pH in the media.

The beneficial properties of probiotics have always been a point of interest. Probiotics play a major role in maintaining the health of Gastrointestinal Tract (GIT), a healthy digestive system is responsible for modulating all other functions of the body. The effectiveness of probiotics can be enhanced by formulating them with prebiotics the formulation thus formed is referred to as synbiotics.

Unregulated pig farming practices expose pigs to fecal sewage and antibiotic stress, which are common health risk factors. Thus, its effects on the animals' intestinal microflora were investigated herein. In total, 2,315,563 high-quality sequences were obtained via amplitude sequencing and, after OUT clustering, the fecal sewage group was identified to have the highest number and the antibiotic exposure group the lowest.
