S-layers represent the simplest biological membranes developed during the evolution and are one of the most abundant biopolymers on Earth. Current fundamental and applied research aim to reveal the chemical structure, morphogenesis and function of S-layer proteins (Slps). This is the first paper that describes the Slps of certain Lactobacillus brevis strain isolated from sauerkraut. The whole genome sequence (WGS) analysis of the L. brevis SF9B strain uncovered three genes encoding the putative Slps, but merely one, identified as similar to the SlpB of L. brevis ATCC 14869, was expressed. Slp-expressing SF9B cells exhibited increased survival in simulated gastrointestinal

“…A worth-noting result was that these emulsions could be obtained at a high oil: water ratio (e.g., 4:1), when full droplet coverage and the close-packed oil droplet arrangement appeared to give gel-like emulsions (Firoozmand and Rousseau, 2016). …”

Pickering emulsion, a kind of emulsion stabilized only by solid particles locating at oil–water interface, has been discovered a century ago, while being extensively studied in recent decades. Substituting solid particles for traditional surfactants, Pickering emulsions are more stable against coalescence and can obtain many useful properties. Besides, they are more biocompatible when solid particles employed are relatively safe in vivo. Pickering emulsions can be applied in a wide range of fields, such as biomedicine, food, fine chemical synthesis, cosmetics, and so on, by properly tuning types and properties of solid emulsifiers. In this article, we give an overview of Pickering emulsions, focusing on some kinds of solid particles commonly serving as emulsifiers, three main types of products from Pickering emulsions, morphology of solid particles and as-prepared materials, as well as applications in different fields.

“…Therefore, the microorganisms seem to behave like hydrophilic solid particles with a contact angle below 90°. Measurements of oil‐water interfaces with an aqueous continuous phase stabilized by the yeast Saccharomyces cerevisiae with contact angles of 30 ± 9° confirm this assumption . This explains both the hindered coalescence and faster sedimentation.…”

“…Reliable phase separation on a technical scale, which is the basis for technical process design, has only been a topic of a small group of researchers . Nonetheless, the influence of cells and microorganisms on the interface and droplets in organic‐aqueous systems has already been investigated . The microorganisms behave like surface‐active particles to hinder coalescence and stabilize the interface , which is partly based on cell adhesion .…”

Optimization of Settling Behavior for an Efficient Solvent‐Extraction Process for Biobased Components

Extraction is a downstream process option in biobased processes. Because knowledge of phase‐separation behavior is essential for designing efficient separation processes, this study investigates the settling and coalescence behavior of biobased extraction systems by using a standard laboratory‐scale settling cell. The influence of different buffer media and Escherichia coli cells on coalescence was determined for the reactive extraction of hexane‐1,6‐diamine with isostearic acid and di(2‐ethylhexyl)phosphoric acid by using kerosene and oleyl alcohol as diluents. As a result, an increasing pH value of the buffer significantly increases the settling time. The presence of E. coli cells hinders phase separation of the investigated systems, in particular, with dispersed organic phases.
