温度对霍夫水丝蚓排粪的影响及其粪便的氨基酸分析

Effect of Temperature on the Defecation Rates of Limnodrilus Hoffmeisteri and the Amino Acid in its Feces

在水温23℃,35℃,40℃条件下,霍夫水丝蚓的排粪率分别为0.31,0.28,0.21mg 粪(干)/mg 虫(干)·h。其粪便及底泥共有16种氨基酸,除苏氨酸外,粪便中的氨基酸的相对含量均高于底泥中者。

The defecation rates of Limnodrilus hoffmeisteri were 0.31,0.28,0.21 mg feces(d.w.)/mg worms(d.w.)/hr at temperatures 23C,35C,40C,respectively. Sixteen amino acids were found both in feces and sediment.The relative amounts of those amino acids,except threonine,were higher in feces than those in sediment.
