Many detritus-feeders prefer dead leaves which are colonized by microorganisms-i.e. conditioned leaves, over freshly fallen or sterile leaves. Traditionally, this has been attributed to the build-up of microbial cells on the substrate. Two experiments show that changes in the leaf itself, brought about by microbial excretions and secretions, or by a hydrolytic agent (hot HCl), can also increase its palatability to the detritus-feeding amphipod Gammarus pseudolimnaeus.
许多食碎屑动物更喜欢被微生物定殖的枯叶，即经过预处理的叶子，而不是刚落下的或无菌的叶子。传统上，这被归因于微生物细胞在底物上的积累。两项实验表明，由微生物排泄物和分泌物或水解剂（热盐酸）引起的叶子本身的变化，也可以增加其对以碎屑为食的双足动物伪沼虾的适口性。
