Summary[edit] Description: Русский: Если в ёмкости остаётся немного воды и эта ёмкость находится вне дома, то со временем (чаще в конце августа или в сентябре) вода приобретает красноватый оттенок. Это зелёные микроводоросли накапливают красный пигмент. Благодаря стрессу происходит деградация хлорофиллов, каратиноидов и накапливается астаксантин. Если пробу рассмотреть под микроскопом, то можно увидеть красивые микроводоросли Haematococcus pluvialis. Красным цвет - это накопление пигмента астаксантина - того самого знаменитого, который является сильным антиоксидантом.English: Haematococcus pluvialis. Date: 5 September 2019, 18:49:31.

The unicellular algae Haematococcus pluvialis in the photo is represented by cells in a dormant stage. In it, to protect against ultraviolet radiation and oxidation, hematococcus begins to produce astaxanthin - a carotenoid, which is a strong antioxidant (used in cosmetics and medicine), it is it that gives the cells such a rich red color.
