Akinets of Haematococcus pluvialis in darkfield, This algae morphes into the akinet form when environmental condictions get bad and produces the red carotenoid astaxanthin to protect itselft from the sun.

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.
