Fuxianospira gyrata is a Cambrian macroalgae found in the Chengjiang lagerstätte. [1] Preserved in clustered, helicoid groups, the filaments are threadlike, plain and without branches. [ 1 ] Brown and smooth in appearance, these structural characteristics display a resemblance to modern brown algae. [ 2 ]
The "Cambrian substrate revolution" [1] or "Agronomic revolution", [2] evidenced in trace fossils, is a sudden diversification of animal burrowing during the early Cambrian period. Before this "widening of the behavioural repertoire", [ 3 ] bottom-dwelling animals mainly grazed on the microbial mats that lined the surface of the substrate ...
For algae to grow, they must be exposed to light because photosynthesis requires light, so algae are typically distributed evenly wherever sunlight and moderate moisture is available. Algae do not have to be directly exposed to the Sun, but can live below the soil surface given uniform temperature and moisture conditions.
Vaxa's plant has a unique situation. It's the only place where algae cultivation is integrated with a geothermal power station, which supplies clean electricity, delivers cold water for ...
Microbial mats use all of the types of metabolism and feeding strategy that have evolved on Earth—anoxygenic and oxygenic photosynthesis; anaerobic and aerobic chemotrophy (using chemicals rather than sunshine as a source of energy); organic and inorganic respiration and fermentation (i..e converting food into energy with and without using ...
The most widely supported explanation is that stromatolite builders fell victim to grazing creatures (the Cambrian substrate revolution); this theory implies that sufficiently complex organisms were common around 1 Ga. [26] [27] [28] Another hypothesis is that protozoa such as foraminifera were responsible for the decline, favoring formation of ...
Dulse is one of many edible algae. Algaculture may become an important part of a healthy and sustainable food system [11]. Several species of algae are raised for food. While algae have qualities of a sustainable food source, "producing highly digestible proteins, lipids, and carbohydrates, and are rich in essential fatty acids, vitamins, and minerals" and e.g. having a high protein ...
Marine and aquatic biomass tentatively demonstrates high yield while requiring minimal use of arable land. Major advantages of algae are: no competition with food crops for arable land, high growth rates, and low fractions of lignin which reduces the need for energy-intensive pretreatment and compatibility with biorefinery approach implementation.
