Abstract
Under stress conditions of high light andnitrogen starvation the green motile cellsof the unicellular green algaHaematococcus pluvialis are known tocease growing and transform into inert redcysts, in which the secondary carotenoidastaxanthin accumulates. A study wastherefore made on other effects of suchconditions. A number ofprotease-resistant, heat-stable proteinswith apparent molecular masses of 38 kDa,50 kDa, 62 kDa and 63 kDa accumulated. Thisprotein fraction was effective in theprotection of horseradish peroxidase frominactivation, suggesting a role for theseproteins in H. pluvialis subjected toa stress event.
