The Chrysophyceae, usually called chrysophytes, chrysomonads, golden-brown algae or golden algae, are a large group of algae, found mostly in freshwater. [3] Golden algae is also commonly used to refer to a single species, Prymnesium parvum, which causes fish kills. [4]

golden algae, (class Chrysophyceae), class of about 33 genera and some 1,200 species of algae (division Chromophyta) found in both marine and fresh waters. The group is fairly diverse in form, and its taxonomy is contentious. Most golden algae are single-celled biflagellates with two specialized flagella.

A golden alga fish kill may last for days, weeks, or months. Sometimes only a portion of a lake is affected, but the location can change from one day to the next. Blooms are more likely to occur in cold weather, and sometimes taper off as the water warms and other species of algae become more active — but not always.

金藻亦称金褐藻（golden-brown algae），金褐色，除含叶绿素外，尚合有较多的类胡萝卜素。 单细胞游动的种类，无细胞壁，有细胞壁的种类，其组成物质主要为果胶。

Golden Algae. Chrysophytes, or golden algae, are common microscopic chromists in fresh water. Some species are colorless, but the vast majority are photosynthetic. As such, they are particularly important in lakes, where they may be the primary source of food for zooplankton.

2022年8月19日 · 金藻纲（Chrosophyceae）学名来自于古希腊语“χρυσóς（chroso）”加上藻类分纲的后缀“-phyceae”。俗名金藻（golden algae）或金褐藻（golden-brown algae），来自于其色素带来的金色。主要生活于淡水。

At high cell densities the water takes on a golden color, giving these blooms their common name, “golden alga.” It is important to note that there are also non-toxic strains of this species, therefore the appearance of a golden bloom does not always mean that the water is toxic.

Golden algae are believed to produce a number of toxins, collectively known as prymnesins, which include an ichthyotoxin, or fish toxin (Ulitzer and Shilo, 1966); a cytotoxin (a substance that is toxic to cells) (Ulitzer and Shilo, 1970); and a hemolysin (a protein that causes the destruction of red blood cells) (Ulitzer, 1973).

6 天之前 · Golden Alga is a tiny, single-celled organism that is about the size of a human blood cell. Algae are primitive aquatic plants that usually lack true stems, roots, or leaves. Golden Alga is fast-growing, resilient, very mobile, and it uses nutrients more effectively than other algae. Two “tails” called flagella enable the Golden Alga to ...

What is Golden Algae? Physical Characteristics. Microscopic and floating (about the size of a human red blood cell) Oval or elliptical shape, single cell alga; Has two hair-like short tails used for swimming and to attach to things, two saddle-shaped chloroplasts; Often …
