Ualikhanov Kokshetau University, Kazakhstan, Kokshetau, Abaya st, 76 The search for new fungi from lichens, the study of the properties of new antibiotics
and the determination of the biological activity of drugs and the development of the
pharmaceutical industry is relevant [1].
31 samples collected from the Komarovsky Bereg Nature Reserve (60°10ʹ N, 29°47ʹ
E), Leningrad Region, Russia were studied. The objects of research are obtained lichen
isolates. Isolates were obtained according to method [2].
The antibacterial activity of the fungal isolates was determined in relation to
E. coli, St. aureus, S. marcescens B-RKM 0059, antifungal activity –
C. albicans ATCC 885-
653 RKM-0475.
Micromycetes with antimicrobial activity were transplanted to a solid medium. All
fungi were grown at room temperature in a dark place for 25 days. Extraction with ethyl
acetate, biologically active oil mixtures of different colors were obtained: from light
yellow to brick red.
The molecular-genetic properties of the 5 most active isolated isolates were
evaluated by DNA isolation, obtaining a PCR product, followed by sequencing and
analysis of nucleotide sequences in the GenBank - BLAST program to determine the
generic and species identification of microorganisms.
31 species were isolated and 11 active species of fungi from lichens with
antimicrobial and antifungal properties were selected:
Desmazirella acicola, Chaetomum globosum, Coniochaeta hofmannii, Trichoderma atroviride, Fungal sp, Coniochaeta ligniaria, Trichoderma harzianum, Fimeariella Rabenhorstii, Coniochaeta sp, Hypocrea lixii, Daldinia loculata. In the future, it is planned to isolate pure antibiotics from them and their
structural identification.
This research has been funded by the Science Committee of the Ministry of Science and Higher Education of the Republic of Kazakhstan (Grant No. AP19679527)» Literature 1.
