Lactiplantibacillus plantarum M5 and Goji Berry extract were co-microencapsulated to maintain the activity of cells during gastrointestinal digestion, and the mechanism by which they could maintain high activity was investigated. The results showed that the microcapsules with 3% Goji Berry extract(A-GE-3) had the largest encapsulation efficiency(EE) of 92.41 ± 0.58%. SEM showed that the structure of A-GE-3 microcapsules were smoother and denser. Cell viability in A-GE-3 microcapsules remained at 7.17 log10 CFU/g after gastrointestinal digestion. Meanwhile, during the gastrointestinal digestion with 3% Goji Berry extract, cell membrane damage detected by fluorescent probes propidium iodide(PI) and 1.1-N-phenylnaphthylamine(NPN) was significantly reduced; the contents of arginine, glutamic acid and oleic acid in cell membrane were increased, which helped to maintain the dynamic balance of intracellular pH and regulated cell membrane fluidity in response to gastrointestinal environment. This study demonstrated the potential of Goji Berry extract as a probiotic protector in gastrointestinal digestion.

Cobalt–Nickel Oxides with Three-Dimensional Hexagon Films for High Performance Supercapacitors
Yinan Lv,Guixia Dong,Lei Li,Jingrui Kang,Weidan Han 성균관대학교(자연과학캠퍼스) 성균나노과학기술원 2018 NANO Vol.13 No.3
Cobalt–nickel oxide electrode materials with three-dimensional hexagon films or flower-shaped structures have been synthesized by a chemical precipitation method at different thermal decomposition temperatures. Nickel ions enter into the lattice of Co3O4 by forming solid solution and promote primary nanoparticles partly self-assemble into three-dimensional hexagon films which interlace with each other to form a flower-like structure. Consequently, cobalt–nickel oxide with a Ni/Co mole ratio of 1:6 at 220 ℃ displays a highest capacitance of 796.16 F/g at 200 mA/g and cobalt–nickel oxide with a Ni/Co mole ratio of 1:3 at 200 ℃ exhibits a highest capacitance of 290 F/g at 10 A/g, which significantly improve the electrochemical properties of Co3O4.

Fusarium wilt caused by Fusarium oxysporum f. sp. niveum (Fon) is the most serious soil-borne disease in the world and has become the main limiting factor of watermelon production. Reliable and quick detection and quantification of Fon are essential in the early stages of infection for control of watermelon Fusarium wilt. Traditional detection and identification tests are laborious and cannot efficiently quantify Fon isolates. In this work, a real-time polymerase chain reaction (PCR) assay has been described to accurately identify and quantify Fon in watermelon plants and soil. The FONRT-18 specific primer set which was designed based on identified specific sequence amplified a specific 172 bp band from Fon and no amplification from the other formae speciales of Fusarium oxysporum tested. The detection limits with primers were 1.26 pg/μl genomic DNA of Fon, 0.2 pg/ng total plant DNA in inoculated plant, and 50 conidia/g soil. The PCR assay could also evaluate the relationships between the disease index and Fon DNA quantity in watermelon plants and soil. The assay was further used to estimate the Fon content in soil after disinfection with CaCN2. The real-time PCR method is rapid, accurate and reliable for monitoring and quantification analysis of Fon in watermelon plants and soil. It can be applied to the study of disease diagnosis, plantpathogen interactions, and effective management.
