Abstract
The ability of the soil-inhabiting ascomycetes Lecanicillium aphanocladii, Talaromyces sayulitensis, Trichoderma harzianum and Fusarium oxysporum to use polyethylene terephthalate (PET) as a sole carbon and energy source has been shown. Utilization of PET by the studied fungi, except for L. aphanocladii, was accompanied by the production of emulsifying compounds. All fungi exhibited the activity of cutinase, the key PET depolymerization enzyme, and a number of oxidoreductases, which apparently catalyze the oxidation of the resulting products: peroxidases in F. oxysporum and T. harzianum, as well as peroxidases and oxidases in L. aphanocladii and Tal. sayulitensis. The data we obtained can be used to develop environmental biotechnologies and contribute to understanding of the processes of degradation/conversion of plastics in natural ecosystems.
期刊介绍：
Applied Biochemistry and Microbiology is an international peer reviewed journal that publishes original articles on biochemistry and microbiology that have or may have practical applications. The studies include: enzymes and mechanisms of enzymatic reactions, biosynthesis of low and high molecular physiologically active compounds; the studies of their structure and properties; biogenesis and pathways of their regulation; metabolism of producers of biologically active compounds, biocatalysis in organic synthesis, applied genetics of microorganisms, applied enzymology; protein and metabolic engineering, biochemical bases of phytoimmunity, applied aspects of biochemical and immunochemical analysis; biodegradation of xenobiotics; biosensors; biomedical research (without clinical studies). Along with experimental works, the journal publishes descriptions of novel research techniques and reviews on selected topics.
