Russian scientists found the composition of mushroom poisons in the brown algae of the White Sea. This was reported by the press service of Moscow State University.
In the tidal zone of the White Sea, brown fucus algae are abundant, which can be observed when the water level drops. They are mainly offered Ascophyllum nodosum, Fucus distichus and F. vesiculosus, and they are distinguished by the ability to adapt to the ecological environment and form ekads – ecological forms (“subspecies”). Among land plants, pines, which differ significantly in structure when growing in swamps or coniferous forests, behave similarly. At the same time, fucus algae is an object of fisheries and is necessary in the manufacture of fertilizers, dietary supplements and cosmetics.
In this regard, biologists from Moscow State University decided to find out what fungal toxins are found in the thalli of these plants. To do this, the authors collected algae from the bottom of Kandalaksha Bay and dried them immediately after extraction, then crushed them and identified 16 possible mycotoxin presences by enzyme immunoassay.
The researchers found that all targeted mycotoxins were present in the thalli of all species studied and in all ecoforms, but the contents of the toxins varied significantly.
“The maximum content of mycotoxins was found for the sublittoral form. F. vesiculosus f. giantcompared to other Ekads vesiculosusand among all fucoids studied. unbound coastal form F. vesiculosus ecad vehovianus In the content of most metabolites, it is significantly lower in dwarf fucus than in the typical supplemented form (F. vesiculosus ekad muscoides), living on the upper coast, the content of mycotoxins studied was even lower. For attached forms F. distichus The composition and amount of mycotoxins were similar. for forms A. nodosum at lower mycotoxin concentrations compared to F. vesiculosus and F. distichusThere was a similar trend towards a decrease in mycotoxin content from a typical bound form living in the upper sublittoral to an unbound littoral form. A. nodosum ekad scorpions and dwarf form A. nodosum ekad muscoideslimited to the upper shore, ”said biologist Marina Georgieva.
This work will not only help to understand the structure of marine ecosystems and clarify the causes of ekad formation, but will potentially reveal new components in algae that are useful to industry.
