The structural characterization and antioxidant activity of four Auricularia polysaccharides (A. cornea (ACP), A. auricula (AAP), A. polytricha (APP) and M.fungus (MFP)) were studied in this paper. The results shown: polysaccharides of four Auricularia were mainly composed of mannose and galactose, all polysaccharides contained uronic acid and pyran ring structure with spectroscopy and NMR anal. There was a significant difference in the total antioxidant capacity and APP was significantly higher than the other polysaccharides. The ability of APP to scavenge DPPH radicals and hydroxyl radicals was significantly higher than that of other polysaccharides, resp. The mol. weight was significantly pos. correlated with DPPH radicals, superoxide anion radicals and hydroxyl radicals. Total antioxidant capacity was significantly neg. correlated with fucose and galactose. The result indicated that fucose and galactose jointly determine total antioxidant capacity. The polysaccharide from four Auricularia had good oxidation resistance and could be used as natural antioxidants.

Hollander, Amit’s team published research in Food Microbiology in 2021-06-30 | 78-70-6

Food Microbiology published new progress about Aggregation. 78-70-6 belongs to class alcohols-buliding-blocks, and the molecular formula is C10H18O, Computed Properties of 78-70-6.

Hollander, Amit; Yaron, Sima published the artcile< Pore-forming treatments induce aggregation of Salmonella Senftenberg through protein leakage>, Computed Properties of 78-70-6, the main research area is Salmonella senftenberg protein pore treatment aggregation; Aggregation; Antimicrobials; Food safety; Membrane damage; Salmonella.

Fresh herbs are not commonly associated with foodborne pathogens, due to the production of essential oils with antimicrobial activity. Recalls of contaminated basil, and basil outbreaks caused by Salmonella motivated studies aimed to comprehend the antimicrobial activity of basil essential oils, and to explore the mechanisms in which Salmonella can overcome them. Linalool, a major constituent of basil oil, increases the permeability of Salmonella Senftenberg cells by damaging their membrane. Linalool also induces bacterial aggregation. We hypothesized that the membrane perforation effect triggers cell aggregation through leakage of intracellular substances from live and dead cells. By exposing S. Senftenberg to addnl. phys. (sonication) or chem. (eugenol, Triton-X-100) treatments, we showed that the aggregation is caused by various membrane-targeted treatments. Enzymic degradation of leaked proteins restricted the bacterial aggregation, and disassembled existing aggregates. Moreover, supplemented proteins such as bacterial intracellular proteins or BSA also caused aggregation, further supporting the hypothesis that non-specific proteins trigger the bacterial aggregation. This study provides a novel understanding of the role of protein leakage in promoting bacterial aggregation. Since aggregation has significant roles in food safety and microbial ecol., this finding may establish future studies about microbial resistance via formation of clusters similar to biofilm development.

Longan pulp polysaccharides were extracted with hot water (LP-H), superfine grinding (LP-S) and superfine grinding-assisted enzymic treatments (LP-SE). The yields, physicochem. properties and prebiotic activities of polysaccharides were investigated. Compared with LP-H and LP-S, the yield, sugar content, solubility, arabinose and mannose percentage of LP-SE increased while its apparent viscosity, particle size, Mw and glucose percentage declined. Three LPs contained similar glycosidic linkage of →3)-α-L-Araf-(1→, →3,6)-β-D-Galp-(1→ and α-L-Rhap(l→, while they each contained specific glycosidic linkage of →4)-β-D-Glcp(l→, →4)-β-D-Galp-(1→ and →5)-α-L-Araf-(1→ in LP-H, LP-S and LP-SE, resp. Moreover, LP-SE exhibited stronger stimulation than LP-H and LP-S on the proliferation of Lactobacillus plantarum, Lactobacillus bulgaricus, Lactobacillus fermentum and Leuconostoc mesenteroides. The results indicated three extraction methods had some effect on chem. composition and structure of polysaccharide. LP-SE extracted by superfine grinding-assisted enzymic treatment exhibited the highest prebiotic activities, which have a great potential in applying in functional food and medical industry.

The optimal purification conditions as follows: elution volume of 2.74 BV, flow rate of 1.88 BV/h, and sample concentration of 2.10 mg/mL. Under the optimal conditions, the purification comprehensive score was 63.59 ± 1.56% (n = 3), which was agreed closely to the predicted value (64.02%). Two fractions of polysaccharides (CMKP-1 and CMKP-2) were obtained using a DEAE-52 column. Fourier Transform IR (FTIR) spectroscopy spectra revealed the general characteristic absorption peaks of CMKP-1 and CMKP-2. Congo-red test indicated that CMKP-1 and CMKP-2 have triple helix conformation. CMKP-1 and CMKP-2 were both composed of Man, Rib, Rha, GluA, GalA, Glu, Gal, Xyl, Ara and Fuc in a molar ratio of 8.93:1:4.62:1.41:1.78:10.7:24.69:4.51:15.92:1.27 and 7.85:1:5.05:1.99:3.15:12.47:15.41:1.54:6.91:3.15, resp.

Ecotoxicology and Environmental Safety published new progress about Algicides. 78-70-6 belongs to class alcohols-buliding-blocks, and the molecular formula is C10H18O, SDS of cas: 78-70-6.

Chen, Yueting; Weng, Yuanyuan; Zhou, Min; Meng, Yiyu; Liu, Jialu; Yang, Lin; Zuo, Zhaojiang published the artcile< Linalool- and α-terpineol-induced programmed cell death in Chlamydomonas reinhardtii>, SDS of cas: 78-70-6, the main research area is Chlamydomonas programmed cell death linalool alpha terpineol algaecide; Algaecide; Chlamydomonas reinhardtii; Linalool; Programmed cell death; α-Terpineol.

Plant allelochems. effectively inhibit and/ or control algal growth, and have potential to use as algaecide. To uncover the lethal mechanism of 2 anti-algal compounds linalool and α-terpineol identified from Cinnamomum camphora extracts, and promote their development as algaecide, the H2O2 production, photosynthetic abilities, H2O2 content burst in linalool treatment at 0.5 h and in α-terpineol treatment at 1 h, with increases of 2.7 folds and 1.3 folds, resp., compared to that at 0 h. The photosynthetic pigments gradually degraded, and Fv/Fm gradually declined to zero, indicating that the cell death was not a necrosis due to the gradual disappearance of physiol. process. In C. reinhardtii cells, the caspase-9-like and caspase-3-like were activated in the treatments with the 2 compounds for 1 h. With prolonging the treatment time, the fluorescent intensity of the cell nucleuses stained by DAPI gradually enhanced and then faded, and the genomic DNA isolated from the cells gradually degraded. These hallmarks indicated that the death of C. reinhardtii cells in linalool and α-terpineol treatments was a (PCD) triggered by the increased reactive oxygen species (ROS). Compared to α-terpineol treatment, linalool treatment showed stronger promoting effects on PCD at the same time point, which may be caused by the higher ROS content inducing higher caspase-9-like and caspase-3-like activities in a short time.
