| 1 | Characterization of spoilage bacterial communities in chilled duck meat treated by kojic acid显示文摘Chilled duck meat is a popularly consumed meat in China but easily perishes at room/low temperature. Kojic acid is usually used as an antimicrobial. This study investigated the sensory scores, total bacteria number, and total volatile base nitrogen (TVB-N) value of chilled duck meat under kojic acid treatment during storage. The results presented that kojic acid suppressed the growth of spoilage bacteria and prolonged the shelf-life of chilled duck meat by at least two days. In further investigation, the bacterial community composition was explored through high-throughput sequencing. Pseudomonas spp. were the predominant spoilage bacteria after 6-day storage and were significantly suppressed by kojic acid. Besides, Brochothrix showed drug resistance and became the dominant bacteria in the kojic acid treated sample after 6-day storage. In conclusion, kojic acid maintained the sensorial, chemical, and microbial quality of duck meat stored at low temperatures. Meanwhile, kojic acid enriched the bacteria composition and showed strong antimicrobial activity against Pseudomonas spp. | Wenfu Hou Qiqi Yue Wen Liu Ji Wu Yang Yi Hongxun Wang | 2021 | Food Science and Human Wellness2021，10，1： | 3 |

| 3 | Comparison of Lipids in Organs of the Starfish Asterias amurensis Associated with Different Treatments显示文摘Lipids were extracted from organs of the starfish Asterias amurensis associated with different treatments(raw-control,boiling and heating),and then analyzed for lipid content,lipid oxidation index,lipid classes and fatty acid composition.Results showed that boiling softened the hard starfish shells,thus facilitating the collection of starfish organs.As compared with raw organs,the boiled organs had lower water content and higher lipid content,possibly due to the loss of water-holding capacity caused by protein denaturation.Both boiling and heating increased the peroxide value(PV),thiobarbituric acid(TBA) value and carbon value(CV) of lipids.Despite slight increases in the content of complex lipids,associated lipid composition had no substantial variations upon boiling and heating.For simple lipids,the content of 1,2-diglyceride decreased in boiled and heated organs,with free fatty acids observed on thin layer chromatography(TLC).However,neither boiling nor heating significantly changed the fatty acid compositions of simple or complex lipids in starfish organs,suggesting that these two treatments had no significant effects on complex lipids in starfish organs.Together,our results indicated that boiling of starfish soon after capture facilitated the handling and extraction of useful complex lipids consisting of abundant glucosylceramide and eicosapentaenoic acid(EPA)-bounded phospholipids. | WANG Qi IKEGAME Keita TAKAHASHI Koretaro XUE Changhu ZHANG Weinong WANG Hongxun HOU Wenfu WANG Yuming | 2013 | Journal of Ocean University of China2013，12，3： | 1 |
| 4 | Insights into simultaneous adsorption and oxidation of antimonite[Sb(III)]by crawfish shell-derived biochar:spectroscopic investigation and theoretical calculations显示文摘Removal of antimonite[Sb(Ⅲ)]from the aquatic environment and reducing its biotoxicity is urgently needed to safeguard environmental and human health.Herein,crawfish shell-derived biochars(CSB),pyrolyzed at 350,500,and 650℃,were used to remediate Sb(Ⅲ)in aqueous solutions.The adsorption data best fitted to the pseudo-second-order kinetic and Langmuir isotherm models.Biochar produced at 350℃(CSB350)showed the highest adsorption capacity(27.7 mg g^(−1)),and the maximum 78%oxidative conversion of Sb(Ⅲ)to Sb(V).The adsorption results complemented with infrared(FTIR),X-ray photoelectron(XPS),and near-edge X-ray absorption fine structure(NEXAFS)spectroscopy analyses indicated that the adsorption of Sb(Ⅲ)on CSB involved electrostatic interaction,surface complexation with oxygen-containing functional groups(C=O,O=C-O),π-πcoordination with aromatic C=C and C-H groups,and H-bonding with-OH group.Density functional theory calculations verified that surface complexation was the most dominant adsorption mechanism,whilstπ-πcoordination and H-bonding played a secondary role.Furthermore,electron spin resonance(ESR)and mediated electrochemical reduction/oxidation(MER/MEO)analyses confirmed that Sb(Ⅲ)oxidation at the biochar surface was governed by persistent free radicals(PFRs)(•O_(2)^(−)and•OH)and the electron donating/accepting capacity(EDC/EAC)of biochar.The abundance of preferable surface functional groups,high concentration of PFRs,and high EDC conferred CSB350 the property of an optimal adsorbent/oxidant for Sb(Ⅲ)removal from water.The encouraging results of this study call for future trials to apply suitable biochar for removing Sb(Ⅲ)from wastewater at pilot scale and optimize the process. | Hanbo Chen Yurong Gao Jianhong Li Chenghua Sun Binoy Sarkar Amit Bhatnagar Nanthi Bolan Xing Yang Jun Meng Zhongzhen Liu Hong Hou Jonathan WCWong Deyi Hou Wenfu Chen Hailong Wang | 2022 | Biochar2022，4，1： | 0 |
