Nostoc flagelliforme, an algae of Nostoc in Cyanomycetes, is a primitive single-celled organism with naked DNA wrapped in nuclear non-nuclear membrane. Widely distributed in deserts and poor soils all over the world, it is named after its black and slender color, such as human hair, and can be eaten. Nostoc flagelliforme belongs to prokaryote, and it is also a kind of common seafood. There are many ways of Nostoc flagelliforme. The most common way is Nostoc flagelliforme seafood soup, which is very delicious and simple. Usually, I eat some Nostoc flagelliforme seafood soup.

Nostoc flagelliforme is hairy, straight or curved, brown, and brown-black after drying. Often, many algae are wound into clusters, and the largest algae cluster has a diameter of 0.5 mm; The width of a single algae body is 0.3-0.5 1 mm when it is dried, and it is sticky and elastic after absorbing water, and its diameter can reach 1.2 mm.

Introduction to the growth environment of Nostoc flagelliforme

Nostoc flagelliforme grows in a desert environment, and its terrain requirements are not strict. It is distributed in mountains, beams, sources, terraces and flat land, and it is mostly concentrated in the top of calcareous hills and dry sunny slopes in the dry grassland zone. The desert grassland is distributed on the sunny slope of the hill on the high plains plane; In desert grassland and grassland desert belt, it is mostly on the edge of wide valley depression or on the gentle slope connected with wide valley depression in layered plateau, but it is rare in sunny slope or shaded place.

Nostoc flagelliforme mainly grows in low hills, with gentle slopes, flat wasteland and alluvial plain between mountains. The parent material of most of the hilly wasteland where Nostoc flagelliforme grows is Quaternary loess. However, Nostoc flagelliforme was not found in farmland, desert, swamp, meadow and salt marsh habitats.
