ShareIce nucleation activity in the freezing-tolerant Antarctic nematode Panagrolaimus davidi.
Author(s) : WHARTON D. A., WORLAND M. R.
Type of article: Article
Summary
Ice nucleation spectrometry was used to look for the presence of ice nucleating agents (INAs), and their inhibitors, in cultures of Panagrolaimus davidi, an Antarctic nematode which survives intracellular freezing. INA activity was absent in both nematode suspensions and homogenates. The nematodes produce a substance which inhibits the nucleation activity of organic INAs but not of an inorganic INA. A thermal hysterisis protein, or a similar ice-active substance may be responsible for the nucleation inhibition.
