“…This compound not only inhibited growth and slowed down the degradation of glucose by M. brunneum but also disrupted its carbon and nitrogen metabolism. Ametryn also induced oxidative stress in the mycelia of M. brunneum (Szewczyk et al 2018).…”

“…These compounds have a carcinogenic effect and disrupt the functioning of the endocrine system in living organisms; therefore, their use is prohibited in the European Union, although their presence is still found in the natural environment. The conducted studies showed the ability of M. brunneum to partially decompose ametryn, a triazines, at an initial concentration of 100 mg L -1 to generate four derivatives (Szewczyk et al 2018).…”

“…Every day substances are being introduced in the environment that have an adverse effect on the balance of the ecosystem and living organisms. Fungi that inhabit the soil are also sensitive to contaminants (e.g., herbicides, insecticides, fungicides and heavy metals) that cause decreased or delayed growth, abnormalities of cellular metabolic pathways, and damage of cellular structures (Ró _ zalska et al 2014;Gola et al 2018;Szewczyk et al 2018;Stolarek et al 2019;Subbanna et al 2019). Adverse changes in the cells caused by these compounds prevent these microorganisms from playing their proper ecological role.…”

Entomopathogenic fungi (EPF) are microorganisms that cause fatal diseases of arthropods. The infection process involves several stages that consist of direct contact of the fungus with the surface of the cuticle of the attacked insect. The factors that determine the effectiveness of the infection process include lytic enzymes, secondary metabolites, and adhesins produced by EPF. Because of their high insecticidal effectiveness, these fungi are commonly used as biopesticides in organic farming. As the environment and farmlands are contaminated with many compounds of anthropogenic origin (e.g., pesticides), the effects of these toxic compounds on EPF and the mechanisms that affect their survival in such a toxic environment have been studied in recent years. This review presents information on the capacity of EPF to remove toxic contaminants, including alkylphenols, organotin compounds, synthetic estrogens, pesticides and hydrocarbons. Moreover, these fungi produce numerous secondary metabolites that can be potentially used in medicine or as antimicrobial agents. Despite their huge potential in biocontrol processes, the use of EPF has been underestimated due to a lack of knowledge on their abilities. In our work, we have presented the available data on the possibilities of the additional and unconventional use of these microorganisms.

MICROBIAL METABOLOMICS: INNOVATIONS AND APPLICATIONS. Over the past few years, metabolomics has been employed in a broad range of applications in different research fields. Microbial metabolomics has been applied in several microbiological areas, such as identification of microorganisms, cell mutations, functional gene approach, identification of unique metabolic pathways and microbial engineering, leading to a better understanding of the global metabolism and metabolic regulation of certain systems. Metabolites produced by microorganisms constitute a large promising group with diverse applications; however, most of these systems are still unknown and underexplored. In this context, the overall analysis of metabolites involved in a biological system can be used to discover potential biomarkers or specific metabolic changes due to a biological phenomenon studied. In this sense, this review aims to understand the main challenges faced by each step of the workflow in the metabolic analysis of microorganisms and how these difficulties have been overcome. A critical analysis of the articles published within the last five years will be accomplished in this paper to understand how these studies have contributed to the microbial metabolomics research. Moreover, major trends observed in this area will be highlighted here in order to guide readers interested in microbial metabolomics in their future researches. Tabela 2.

Scenedesmus species, immobilized on alginate gel, was found effective in removing nitrate, atrazine, magnesium, phosphorus, zinc, oxadiazon, and triallate from groundwater in a continuous flow reactor. The laboratory‐scale experiments with synthetic groundwater, made of 8.8 mg/L NO3‐N and 90 µg/L atrazine, were performed at a hydraulic retention time of 7 days and the temperatures of 20 and 35°C. The highest uptake of nitrate and atrazine was observed at 20°C (97% and 70%, respectively). When tested in actual groundwater, 92% of nitrate, 100% of magnesium, 99.9% of phosphorus, and 92% of zinc were successfully removed at the end of 29 days’ treatment operations. The algal beads removed 100% of oxadiazon and triallate in the first 10 days, but some of the herbicides diffused back into the solution toward the end of the treatment process. Practitioner points Immobilized algae–alginate beads can remove nitrate, atrazine, oxadiazon, and triallate from groundwater in continuous flow reactor. The uptake rate of nitrate and atrazine is higher in room temperature (20°C). Same algae beads could be reused for herbicide uptake for the average of 10 days. The immobilized system is a natural sustainable alternative that can be used in groundwater pump and treat.
