SALT-RESISTANT EUGLENA, SELECTIVE CULTIVATION OF SALT-RESISTANT EUGLENA, AND CULTIVATION OF SALT-RESISTANT EUGLENA

摘要

PURPOSE:To obtain a salt-resistant Euglena which can be proliferated in a medium having high salt content corresponding to that of sea water, by the gradual accommodation of Euglena with aqueous solution containing the salt of sea water. CONSTITUTION:Euglena is inocultated in a medium consisting of an aqueous solution containing =0.1% salt of sea water, and the accommodation and culture are carried out until the number of cells reaches 15-20X106/ml. The salt concentration is increased to =2 times that of the former process, and the Euglena prolferated in the former stage is inoculated and subjected to the accommodation and cultivation. The procedures are repeated until the salt concentration in the medium reaches 3.0-3.6%. A Euglena living in fresh water can be culture in a medium having the composition of sea water.
