Bacillus coagulans can help ameliorate or prevent gastrointestinal diseases, but the genetic relationships among B. coagulans isolates are not well studied. Multilocus sequence typing analysis was conducted on 57 isolates of B. coagulans from 22 provinces or autonomous regions in China. B. coagulans isolates were highly diverse and a total of 33(sequence typings) STs were found. These isolates had a weak clonal population structure and strong indications of intraspecies recombination. The evolution direction of B. coagulans was not correlated with geography or isolation source. Fifteen strains were selected for further analysis based on proximity relationships from the phylogenetic tree. Five isolates(B. coagulans-1, B. coagulans-10, B. coagulans-39, B. coagulans-70 and B. coagulans-71) with good spore-forming ability relative to the rest of the isolates were evaluated for constipation relief. B. coagulans-39 significantly relieved constipation symptoms in mice by regulating intestinal flora, increasing the production of short-chain fatty acids and restoring the level of gastrointestinal regulatory peptides. Comparative genomic analysis showed the beneficial effects of B. coagulans-39 might be associated with specific functional genes that are involved in the utilization of various carbohydrates as primary substrates and short-chain fatty acid production.

Lithium-sulfur(Li-S) batteries can provide far higher energy density than currently commercialized lithium ion batteries, but challenges remain before it they are used in *** of the challenges is the shuttle effect that originates from soluble intermediates, like lithium polysulfides. To address this issue, we report a novel laminar composite, N,O-carboxymethyl chitosan-reduced graphene oxide(CC-rGO), which is manufactured via the self-assembly of CC onto GO and subsequent reduction of GO under an extreme condition of 1 Pa and-50°C. The synthesized laminar CC-rGO composite is mixed with acetylene black(AB) and coated on a commercial polypropylene(PP) membrane, resulting in a separator(CC-rGO/AB/PP) that can not only completely suppress the polysulfides penetration, but also can accelerate the lithium ion transportation, providing a Li-S battery with excellent cyclic stability and rate capability. As confirmed by theoretic simulations, this unique feature of CC-rGO is attributed to its strong repulsive interaction to polysulfide anions and its benefit for fast lithium ion transportation through the paths paved by the heteroatoms in CC.

This study investigated the intervention ability and potential mechanism of Lactobacillus helveticus–derived whey on ovariectomy (OVX)-induced osteoporosis. The whey from two L. helveticus strains， ATCC15009， and CCFM1096， were orally gavaged to OVX rats at a dose of 500 mg/kg for 12 weeks. The effect of L. helveticus-derived whey on osteoporosis varied， whereas the raw milk-derived whey showed no significant effect. CCFM1096 whey significantly enhanced bone biomechanics， improved bone microstructure， upregulated bone formation markers (BALP， OPG)， and downregulated bone resorption markers (TRAP， CTX-1， PINP)， leading to promotion of osteoblast formation and inhibition of osteoclast generation. CCFM1096 whey affected bile acid metabolism， restored intestinal homeostasis， and prevented osteoporosis in OVX rats， with higher concentrations of unsaturated fatty acids， orotic acid， and uridine than that of ATCC15009. These findings provide important insights for the development of functional dairy products targeting osteoporotic populations and further demonstrate the importance of starter cultures in fermented foods.

Luminescent materials with multi-emission features are difficult to be replicated, which are highly desirable for advanced anti-counterfeiting. Here, we report the pioneering synthesis of Mn^(2+)/Yb^(3+)/Er^(3+) tri-doped Cs2Ag0.8Na0.2InCl6 double perovskites (MYE-DP), which exhibit photoluminescence (PL) covering from visible to near-infrared (NIR). The PL colors under excitations of 254 and 365 nm are notably different due to the changed relative emission intensities of self-trapped excitons (STEs) and Mn^(2+) d–d transition. Moreover, under the excitation of a NIR laser, the MYE-DP exhibits upconversion (UC) emissions of Mn^(2+) and Er^(3+). After ceasing the excitation, the long-lived trapped electrons can be thermally released to Mn^(2+) and Er^(3+) ions, resulting in both visible and NIR afterglow. Based on multi-modal emissions of the MYE-DP, we demonstrate a five-level anti-counterfeiting strategy, which significantly increases the anti-counterfeiting security. In addition, this work provides valuable insights into the energy transfer between STEs, Mn^(2+), Ln^(3+), and traps, laying a solid foundation for future development of new lead-free perovskites.

Solvent Effect on Photo / Thermo Responsive behaviour and Application of Poly(N-isopropylacrylamide) End-capped with 4-Propoxyazobenzene in Aqueous Media

The photoisomerisation behaviour of Poly(N-isopropylacrylamide) end-capped with 4-propoxyazobenzene (PNIPAM-Azo-OC3H7) was studied in a conconsolvent mixture of water and dioxane. The trans-cis isomerisation rate of PNIPAM-Azo-OC3H7 was mildly affected by the solvent compositions. Interestingly, the addition of dioxane could not only change the lower critical solution temperature (LCST) of PNIPAM-Azo-OC3H7 aqueous solution but also accurately controlled the increase or decrease in the LCST during UV irradiation. The LCST change (ΔT) could be adjusted from −5.0°C to 10.0°C, which was affected by the cononsolvent type, the second solvent and polymer concentration. Transmission electron micrographs (TEMs) showed that the PNIPAM-Azo-OC3H7 solution could self-assemble into different nano-micelles in different amounts of miscible solvents. UV irradiation of PNIPAM-Azo-OC3H7 solution was found to induce different changes in particle shape and size, which in turn led to either decrease or increase in the LCST changes in this novel responsive system. Furthermore, Nile red was tested here as a fluorescence probe for photo-induced release from PNIPAM-Azo-OC3H7 micelles, and the results suggested that this polymer could be used as a hydrophobic chemotherapeutic drug carrier for controlled release. © 2021 Informa UK Limited, trading as Taylor & Francis Group.
