  • 摘要: 对南海北部神狐海域Site 4B站位现代沉积物中脂肪酸组分进行了分离,主要讨论了支链脂肪酸和单不饱和脂肪酸的来源,认为i/a-C15:0i/a-C17:0、16:1ω5和18:1ω9来自硫酸盐还原菌(SRB),而16:1ω7t/c和18:1ω7来自硫氧化菌(SOB)。沉积物中SRB和SOB分布形式可能和硫酸盐还原作用生成硫化物、硫化物又被氧化生成硫酸盐和元素硫、元素硫歧化作用生成硫化物和硫酸盐有关,并在整个硫循环系统中SRB起到主导作用;而在95~97 cm层位剧增的SRB和SOB生物量与站位附近底辟构造活跃带来深部大量的营养流体有关。

摘要: 对南海北部神狐海域Site 4B站位现代沉积物中脂肪酸组分进行了分离,主要讨论了支链脂肪酸和单不饱和脂肪酸的来源,认为i/a-C15:0i/a-C17:0、16:1ω5和18:1ω9来自硫酸盐还原菌(SRB),而16:1ω7t/c和18:1ω7来自硫氧化菌(SOB)。沉积物中SRB和SOB分布形式可能和硫酸盐还原作用生成硫化物、硫化物又被氧化生成硫酸盐和元素硫、元素硫歧化作用生成硫化物和硫酸盐有关,并在整个硫循环系统中SRB起到主导作用;而在95~97 cm层位剧增的SRB和SOB生物量与站位附近底辟构造活跃带来深部大量的营养流体有关。
