“…In particular, the introduction of CB increased the sorption capacity of plant biomass up to 98.52% in sample series f and up to 98.10% in sample series d. This is probably due to the utilization of PP by microorganisms as a nutrient medium. In general, the ability of CB to utilize various pollutants has been described in many works [6,9]. This property is associated with the presence of specific enzyme systems in the microorganisms under consideration, which are capable of degrading pollutants to simple compounds.…”

“…CB Nostoc Paludosum are widely used in biotechnology: they are used in the production of fertilizers, for bioindication and wastewater treatment from PP and other pollutants. Thus, the CB communities isolated from oil-contaminated habitats are able not only to adapt to PP, but also to activate the process of PP purification, both in aquatic and soil ecosystems [6][7][8][9].…”

The development of technologies for extracting metals from waste is an urgent task. In this study, a poorly studied technology for the extraction of metals from electronic waste by microscopic algae, based on the biosorption method, was considered. The efficiency of the technology is determined both by the parameters of the biosorption process (properties and dose of biomass, temperature, pH, contact time of the adsorbate with the biosorbent), and the chemical composition of the solution obtained during the leaching of prepared electronic waste and containing metals. In the course of the study, the presence of functional groups in the biosorbent that could enter into chemical interaction with the recovered metals, the chemical properties of metals in the test solution were identified, and the leaching of the sorbed metals from the biosorbent was assessed. Microscopic algae of the species Chlorella sorokiniana, Chlorella vulgaris, Chlorella spirulina, and the genus Scenedesmus sp. were used as a biosorbent. The metal was sourced from mobile phone/smartphone screens and computer monitors. Analysis of the component composition of screens and monitors showed that it is represented by more than 10 different metals belonging to the group of basic metals and 7 metals belonging to the group of rare earth, rare and precious metals. Using the method of IR spectroscopy, the presence of the following functional groups in the cell walls and organoids of microscopic algae was proved: amino groups, hydroxyl and carboxyl groups. The results of experimental studies have established a mixed mechanism of biosorption, including physical sorption and chemisorption. As evidence, we used data on the partial leaching of sorbed metals from microscopic algae after the completion of the process.

“…Немаловажен также аспект, связанный с влиянием гербицидов на микрофлору почвы, осуществляющей важнейшие функции синтеза и деградации органических веществ, азотфиксации, гумификации, круговорота биогенных элементов и др. Внесение и накопление гербицидов может приводить к локальным для данной территории перерождениям микробных комплексов, а, следовательно, и нарушениям указанных биогеохимических процессов [5].…”

The review is devoted to the problems of application of modern imidazolinone and ulfonylurea herbicides, as well as to the researches in the field of microbial iotechnology for remediation of contaminated soils. Data on the traits of the influence of residual amounts of herbicides from the classes of imidazolinones and sulfonylureas on target and subsequent crops in crop rotations are given in the article. The problems of monitoring of herbicide residues due to the variety of properties of components and decomposition mechanisms in the soil are shown. Ecological aspects of the influence of imidazolinones and sulfonylureas on soil microbiota and non-target organisms are considered. The results of studies of the biodegradation pathways of herbicide components, as well as conditions that contribute to the acceleration of destructive processes, are presented. The relevance of the search for microorganisms-destructors of imidazolinones and sulfonylureas for the production of biological products is substantiated. Microorganisms of different genera, such as Rhodococcus, Rahnella, Pseudomonas, Bacillus, Methylopila, Ancylobacter, Hansschlegelia, Klebsiella, and Arthrobacter, possess destructive potential against imidazolinones and sulfonylureas. The current data on the development of biological products to eliminate residues of imidazolinones and sulfonylureas in soils to reduce the phytotoxic effect are given.
