We investigated geochemical properties, and microbial sulfate- and iron(III) reduction in sediment influenced by the aquaculture of abalone in the Nohwa-do, southern coastal sea in Korea. Concentrations of ammonium, phosphate, and sulfide in the pore-water were higher at farm sites than at control s...

양식업의 급속한 성장 시 일으킬 수 있는 문제점은? | 9%까지 증가하였다(KMI 2011). 그러나 양식업의 급속한 성장은 연안에서 부영양화와 적조 등의 심각한 환경문제를 일으킬 수 있다(FAO 2002, 2006). 일반적으로 여과식자인 이매패류(굴, 홍합) 양식은 수층의 일차 생산력에 의해 양식 생산이 결정된다. | |
미생물들은 어떻게 유기물을 분해시키는가? | 유기물 유입이 많은 퇴적물에서는 퇴적물 수 mm 이내에서 산소가 빠르게 소모되어 대부분의 유기물 분해가 혐기성 환경에서 이루어진다. 다양한 미생물들이 질산염, 망간 산화물, 철 산화물, 황산염 등과 같은 전자수용체를 사용하여 유기물을 분해한다(현 등 2003; Kostka et al. 2002). | |
황산염 환원의 결과로 생성된 황화수소가 축적될 때 생기는 문제는? | 2005), 황산염 환원의 결과로 황화수소가 생성되고, 혐기성 분해의 결과로 암모니아가 생성되어 퇴적물 내에서 축적된다. 이러한 황화수소와 암모니아의 축적은 강한 독성으로 인해 저서생물의 다양성을 감소시킨다(Bagarinao 1992; Hargrave et al. 1993; Holmer et al. |
