Protist Interactions and Seasonal Dynamics in the Coast of Yantai, Northern Yellow Sea of China as Revealed by MetabarcodingJournal of Ocean University of Qingdao - Tập 19 - Trang 961-974 - 2020
Yingjun Fu, Pengfei Zheng, Xiaoli Zhang, Qianqian Zhang, Daode Ji
Facilitated by the high-throughput sequencing (HTS) technique, the importance of protists to aquatic systems has been widely acknowledged in the last decade. However, information of protistan biotic interactions and seasonal dynamics is much less known in the coast ecosystem with intensive anthropic disturbance. In this study, year-round changes of protist community composition and diversity in th...... hiện toàn bộ
Isolation, Identification, and Quantitative Determination of Saponin in Apostichopus japonicus by HPLC-DADJournal of Ocean University of Qingdao - Tập 21 - Trang 473-478 - 2022
Guiying Liu, Xuda Wang, Kun Ge, Jinhao Wu, Zhaohui Wang, Jing Du, Lun Song, Zunchun Zhou
Apostichopus japonicus is an important invertebrate that is widely used as a tonic food in Asian countries. The purpose of this study is to purify and identify a class of compound, the saponins, from the body wall of A. japonicus, and to establish a new method to determine the quantity of saponins in the sea cucumber. In this study, the saponins of A. japonicus, cladoloside A (CA), were obtained f...... hiện toàn bộ
Mineral components and anti-oxidant activities of tropical seaweedsJournal of Ocean University of Qingdao - Tập 4 - Trang 205-208 - 2005
Suzuki Takeshi, Yoshie-Stark Yumiko, Santoso Joko
Seaweeds are known to hold substances of high nutritional value; they are the richest resources of minerals important to the biochemical reactions in the human body. Seaweeds also hold non-nutrient compounds like dietary fiber and polyphenols. However, there is not enough information on the mineral compounds of tropical seaweeds. Also we are interested in the antioxidant activities of seaweeds, es...... hiện toàn bộ
Energy Consumption and Greenhouse Gas Emission of Korean Offshore FisheriesJournal of Ocean University of Qingdao - Tập 17 - Trang 675-682 - 2018
Jihoon Lee, Taeho Kim, Harald Ellingsen, Erik Skontorp Hognes, Bokyu Hwang
This paper presents the energy and greenhouse gas (GHG) emission assessments of Korean offshore fisheries. The consumption of energy by fisheries is a significant concern because of its attendant environmental effect, as well as the cost of the fuel consumed in fishing industry. With the global attention of reducing GHG emission and increasing energy efficiency of fuel, the seafood industry needs ...... hiện toàn bộ
Numerical simulation for accuracy of velocity analysis in small-scale high-resolution marine multichannel seismic technologyJournal of Ocean University of Qingdao - Tập 16 - Trang 370-382 - 2017
Di Luo, Feng Cai, Zhiqiang Wu
When used with large energy sparkers, marine multichannel small-scale high-resolution seismic detection technology has a high resolution, high-detection precision, a wide applicable range, and is very flexible. Positive results have been achieved in submarine geological research, particularly in the investigation of marine gas hydrates. However, the amount of traveltime difference information is r...... hiện toàn bộ
