“…This situation usually leads to higher toxicity of the environment. Therefore, the microorganisms able only to modify toxic compounds probably cooperate with other organisms to achieve complete mineralization of contaminants into CO 2 and H 2 O or at least transform the parent compounds into less or nontoxic intermediates [76].…”

The chapter describes the aspects of bioremediation that are related to survival and metabolism of bacterial degraders in the adverse environment contaminated with dangerous hydrophobic chemicals, polychlorinated biphenyls (PCBs). Successful environment decontamination requires bacterial strains that possess appropriate enzymes and are able to degrade particular contaminants. This chapter deals mainly with the adaptation mechanisms that allow bacteria to decrease toxic effects of the dangerous compounds on cytoplasmic membrane as the first contact point of pollutants and the bacterial cell. Many responses have been observed in bacteria that counteract the effects of toxic environmental organic pollutants: saturation-rigidification of cell membrane, cis/trans isomerization of fatty acids, increased content of cyclopropane fatty acids, and changes in branched fatty acids and cardiolipin, production of stress proteins, and elimination of toxic compounds using efflux pump. The study of these mechanisms is the first step in selection of appropriate resistant bacterial strains for bioremediation applications. Next steps should include study of degradation potential and efficacy of the most resistant strains. Setting up suitable experimental systems to examine the cell responses to toxic environmental organic pollutants in the adverse environment and optimal conditions for metabolism of bacterial degraders are important issues in the current bioremediation research agenda.

“…In Lizano-Fallas et al (2017), for example, the ecotoxicity test with Daphnia magna 585 showed clear detoxification, whilst the detoxification patterns remain unclear when applying the 586 phytotoxicity test. Ecotoxicological tests can also be used to determine the most suitable 587 bioremediation technique in a given case, as reported in Dudášová et al (2016).…”

Pesticides can help reduce yield losses caused by pests, pathogens, and weeds, but their 22 overuse causes serious environmental pollution. They are persistent in the environment and 23 are biomagnified through the food chain, becoming a serious health hazard for humankind. 24 Bioremediation, where microbes are used to degrade pesticides in situ, is a useful technology. 25 This review summarizes data on the fungi involved in the biodegradation of chemical 26 pesticides; and their application in soil and water bioremediation. Indications for future 27 studies in this field are given.
