This study was conducted to isolate the cellulolytic bacteria able to grow on LB- Carboxymethyl cellulose (CMC) agar trypan blue medium from the mixed forest and Larix leptolepis stands. Three bacterial strains with high activity against both CMC and xylan were isolated. Both API kit test and 16S rR...

산림토양의 대표적인 세균은 무엇이 있는가? | 기존에는 대부분의 목질계바이오매스 분해는 목재부후균의 활동과 관련이 있다고 알려졌지만, 메타게놈분석법의 발전으로 이전의 연구방법으로는 알려져 있지 않은 다양한 종류의 미생물들이 여기에 관여한다는 것이 알려졌다. 최근의 연구결과에 의하면 산림토양의 대표적인 세균은 Pseudomonas속, Bacillus속, Rhizobacter속, Arthrobacter속, Paenibacillus속 등 이다(Wilson 2011; Yang 등,2014). 이와 같이 산림에는 목질바이오매스를 분해하여 먹고 사는 다양한 종류의 미생물들이 존재하기 때문에 산업적으로 유용한 미생물을 탐색하기 위한 중요한 보고이다(Li 등, 2009). | |
목질바이오매스를 분해하여 먹고 사는 순수 미생물들의 적용가능한 산업분야는 무엇인가? | 이와 같이 산림에는 목질바이오매스를 분해하여 먹고 사는 다양한 종류의 미생물들이 존재하기 때문에 산업적으로 유용한 미생물을 탐색하기 위한 중요한 보고이다(Li 등, 2009). 이러한 지역에서 순수 분리한 우수한 미생물들은 펄프산업, 식품 산업, 바이오에탄올 생산 등과 같은 각종 산업에 적용 가능하다. 특히, Bacillus속은 목질바이오매스를 분해하는데 필요한 다양한 효소들을 생합성 할 뿐만 아니라 효모나 곰팡보다 상대적으로 배양이 쉽고, 생장속도가 빠르고, 유전자 조작이 가능하기 때문에 식품산업, 펄프산업, 동물 사료산업 등과 같은 다양한 산업에 이용되고 있다(Lynd 등, 2002; Tjalsma 등, 2004; Khandeparker 등, 2011; Zang과 Zhang 2011). | |
리그노셀룰로오스란 무엇인가? | 리그노셀룰로오스는 광합성에 의해 합성되는 지구상에서 가장 풍부한 유기물로 셀룰로오스, 헤미셀룰로오스, 리그닌 등으로 구성되어 있다(Whitaker 1990; Kim 등, 2012). 피자식물의 경우 일반적으로 42-50% 셀룰로오스, 25-30% 헤미셀룰로오스, 20-25% 리그닌, 5-8%의 기타 유기물로 구성되어 있다(Kumar 등, 2008). |
