In this study, gut bacterial communities in xylophagous insects were analyzed using the pyrosequencing of 16S rRNA genes for their potential biotechnological applications in lignocelluloses degradation. The result showed that operational taxonomic units (OTUs), species richness and diversity index w...

바이오 에탄올을 생산하는 방법은 무엇인가? | , 2005), 섬유소를 기반으로 얻을 수 있는 바이오연료가 주목을 받고 있다(Sun and Scharf, 2010). 바이오 에탄올은 바이오매스의 섬유소 부분을 가수분해하여 얻어진 단당류를 발효하여 생산되며(Hamelinck et al., 2005), 미생물을 이용한 발효 공정은 다른 방법들에 비해 경제적이고 환경친화적이라는 장점이 있다(Eijsink et al. | |
인간의 장내 세균은 어떤 역할을 하는가? | 곤충은 지구상에서 가장 다양하고 풍부한 동물 중 하나이며(Engel and Moran, 2013), 곤충의 장내에는 많은 미생물들이 서식하고 있다(Dillon and Dillon, 2004). 곤충의 장내에 공생하는 세균은 숙주의 생리 대사 조절, 섭식한 먹이의 소화 효율 촉진, 외부로부터 유입된 유해한 미생물의 억제 등의 중요한 역할을 수행하며(Kaufman and Klug, 1991; Dillon and Charnley, 2002; Engel and Moran, 2013), 인간의 장내 세균의 경우에는 영양분을 합성하고 면역체계와 관련한 상호작용 등의 역할을 수행한다(Clemente et al., 2012). | |
사슴벌레, 하늘소, 갑옷바퀴, 흰개비 등의 목질 섭식 곤충의 세균 군집 분석결과 중장보다 후장에서 수치가 높았던 항목에는 무엇이 있는가? | 본 연구에서 목질 섭식 곤충의 장내 세균 군집은 16S rRNA 유전자를 기반으로 한 파이로시퀀싱 방법을 이용하여 분석되었다. 분석된 모든 곤충에서 중장보다 후장에서 OTU수, 종 풍부도, 다양성 지수가 높았다. 세균 문 또는 강 수준의 다양성을 분석한 결과, 흰개미를 제외한 곤충의 장내 군집에는 Firmicutes, Bacteroidetes, ${\gamma}-Proteobacteria$가 우점하였다. |
