Pyrosequencing of 16S rDNA tags was used to obtain the bacterial diversity and community structure in the uncultured seawaters as well as in the cultured seawaters, which were collected from the 7 ports (Cheonbu, Hyunpo, Taeha, Namyang, Sadong, Dodong, and Jeodong) and 1 seashore (Guam) around the U...

육지 근해의 해수 오염의 원인은 무엇인가? | 육지 근해의 해수 오염은 바다로 방출되는 생활하수나 산업폐수(Chandía and Salamanca, 2012; Araújo et al., 2014; Khang, 2014), 농축산업의 부산물로 발생하는 바이오매스(Lambert et al., 2009), 원유 성분인 polycyclic aromatic hydrocarbons (Montevecchi et al., 2012; Sinaei and Mashinchian, 2014), 플라스틱류를 포함하는 생활쓰레기(Van Cauwenberghe et al., 2013; Cózar et al., 2014), 어선들이 버린 폐그물(Arthur et al., 2014) 등이 원인이 되고 있다. 해수로 유입된 환경오염 물질들은 미생물에 의해서 분해되지만 청정한 바다에서 서식하는 해양미생물은 육지의 토양미생물에 비하면 오염 물질을 정화하는 능력이 크게 부족하다(Bengtsson-Palme et al. | |
울릉도는 어떤 곳인가? | 울릉도는 경상북도 포항에서 217 km 떨어져 있으며 동해의 깊은 바다 한가운데에 위치한 고립된 섬이며 자연경관이 수려하여 주요 관광지로 개발되고 있다. 울릉도에는 약 일만 명 정도의 주민들이 73 km2 면적에서 살고 있으며, 섬 주변의 해안에는 어선들이 이용하는 지방어항(천부항, 태하항)과 국가어항(현포항, 남양항, 사동항, 저동항), 그리고 관광객들이 이용하는 페리항(도동항)이 개발되어 있다. | |
해수의 오염으로 인한 해양 생태계의변화를 모니터링할 때, 해양미생물의 분포를 조사하는 방법이 도움되는 이유는? | , 2007) 등이 활용되고 있다. 특히 해양미생물은 해수의 온도, 염도, 용존산소, 영양물질, 오염물질의 농도 등에 민감하기 때문에 해양미생물의 분포를 조사하면 환경변화에 따른 해양 생태계의 변화를 이해하는데 도움이 된다(Suh et al., 2015). |
