STUDY OF THE PROCESS OF SOLID-PHASE CULTIVATION OF HIGHER FUNGI ON MILLED SUNFLOWER SEEDS HULLS FOR THE OBTAINING OF COMPOSITE MATERIALS

Currently, there is a great interest in the research of basidial fungi as ligninolytic enzymes producers capable of plant waste degradation. These properties are promising in composite materials creation, which can be employed as bio-packaging, bioplastics, and building materials. The purpose of the work was to study the possibility of using sunflower seed hulls for the cultivation of lignin-destroying fungi for the further development of composite biodegradable materials based on the obtained products. For that point, Trametes polyzona (Pers.) Justo (2011) and Trichaptum abietinum (Dicks.) Ryvarden (1972) growth on solid nutrient media based on sunflower seeds hulls were explored. It was shown that the fungi cultivation duration of the Trametes polyzona is 10 days and of the Trichaptum abietinum KS10 is 7 days. The suitability of the obtained products for use in the composition of biodegradable composite materials was assessed visually. The most durable structure of the packaging composite was obtained on nutrient media based on milled sunflower seeds hulls with the oat bran addition.
