藉分析沉积物样品的水草取物、酸萃取物、和残渣,研究了近代海洋硅藻质软泥中的总有机质。以总有机碳为基准的萃取数据说明了有机碳主要来自糖类(22%),挥发物(12%),和蛋白质(11%),和少量类脂(4%)和挥发性脂肪酸(1%)。残渣中的有机碳(50%)主要具有脂肪族特性。从萃取物中鉴定出的化合物能够区分出有些来自藻类,有些来自细菌。 By analyzing the sediment samples of aquatic plant extracts, acid extracts, and residues, the study of modern marine diatom slime in the total organic matter. Extracted data based on total organic carbon show that organic carbon is mainly derived from sugars (22%), volatiles (12%), and protein (11%), with minor amounts of lipids (4%) and volatile fatty acids %). Organic carbon (50%) in the residue mainly has aliphatic characteristics. Compounds identified from the extract distinguish some from the algae and some from the bacteria.
