Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

One of the modern methods used in the development of environmentally friendly technologiesfor protecting the environment and restoring natural resources is bioremediation, which is the mostsparing method for preserving biodiversity and ensuring the sustainability of cleansing biocenoses. Theformation of this area of scientific knowledge was held in the 1990s and intensive development of ecobiotechnologies is currently taking place. The use of cyanobacteria and microalgae resistant to pollutedwaters, introduction of higher aquatic plants into the purifying consortium, allows the creation of a newintegrated biotechnology for the purification and restoration of polluted water bodies. The aim of the research was the formation of structured biocenoses, including organisms of differenttaxonomic groups, for selecting optimal parameters for controlling bioremediation processes.It was determined that a more positive effect between organisms was observed in consortia: Ankistrodesmus sp. BI-1 + Anabaena variabilis RI-5 + Pistia stratiotes and Schenedemus quadricauda B-1 +Anabaena variabilis RI-5 + Pistia stratiotes. It was determined that during all the time of joint existenceall the components of the consortium stimulated the development of each other, the dynamics of growthof all members of the consortium significantly exceeded the growth of these organisms in monocultures.The obtained results indicate that the use of the HAP consortium, microalgae and cyanobacteria inwastewater treatment in laboratory conditions is very effective in comparison with the use of plants,microalgae and cyanobacteria separately.Key words: microalgae, cyanobacteria, bioremediation, consortium, higher aquatic plants.
