摘要：

SUMMARY. Organic detritus resulting from microbial attack on algal material contains lipids directly extractable by organic solvents and also contains bound lipids, obtained by solvent extraction following acid hydrolysis. Differences between the composition of bound and extractable n‐alkanes, n‐ and branched/cyclic alkanoic acids from each source are attributed to a major bacterial input to these bound lipid classes. Similarities in composition between bound lipid classes of algal detritus and corresponding classes in a lake sediment support earlier suggestions of a considerable bacterially‐derived contribution to sedimentary bound lipids.
