55th Meeting of the Polish Botanical Society, Warsaw 2010 munities were obtained, two in one year from each of the soil profiles (from muck and peat). In total, they were created by 117 fungi isolates, which were represented by 25 different species. Unfortunately, none of them appeared in all communities simultaneously. The fungi communities were characterized by a low frequency and small diversity. The number (frequency) was also low for particular species. The communities did not show any common qualities. The possible similarity between fungi communities amounted to 14–17 %. The results indicate that composition of fungi communities in slightly mucked peatmuck soils is not only determined by soil process. Also, quite significant are the site conditions which have been influencing the shaping of the soil profile. BIOACTIVE COMPOUNdS IN SHIITAKE – CONTENTS OF LENTHIONINE dEPENdING ON SUBSTrATE ANd VArIETY Woźniak Wanda1 , Filipowicz Krzysztof. Poznań University of Life Sciences, 31 Wojska <strong>Polskiego</strong> St., 60-624 Poznań, Poland; Institute of Food Technology of Plant Origin; 1wozwa@ up.poznan.pl Fungi found in nature are not only a symbol of flavour in many dishes, but are also exceptionally valuable sources of biologically active compounds. Biologically active compounds have an effective influence on the functioning of the organism and prevent the incidence of many diseases. Such fungi include shiitake Lentinus edodes (Pegler), which is increasingly available on the retail market in Poland. Compounds contained in this mushroom have an advantageous effect on human health. Shiitake contains a polysaccharide lenthionine and eritadenine. Lenthionine exhibits a proven immunostimulatory effect, thanks to which we may effectively fight neoplasmic lesions in our organism; moreover, it shows an antibacterial, anti-inflammatory, hypoglycemic and anticarietic action. What is more, it reduces blood LDL cholesterol level as well as protects skin cells against the effect of external substances. The compound of eritadenine is also capable of reducing cholesterol levels in blood and the liver. In the case of the two varieties of shiitake tested at the Institute of Technology of Food of Plant Origin, on three different substrates, it turned out that the substrate enriched with yellow flowered gourd pulp had a positive effect on yield and lenthionine level in fruiting bodies irrespective of the variety. PoLyPoRE fUNGI of SŁoWIńSKI NAtIoNAL PARK Zduńczyk Anna. Pomeranian Academy in Słupsk, Department of Biology and Environmental Protection, Department of Botany and Genetics, 22 B Arciszewskiego St., 76-200 Słupsk, Poland, azdunczyk@apsl.edu.pl Research was done in chosen reserves, i.e.: Nature Strict Protection Area Dołgie Małe, Nature Strict Protection Area Mierzeja, Rezerwat Ochrony Częściowej Rowy and Nature Partial Protection Area Rowokół in 2006– 2009. The occurrence of 380 quotations with more than 20 species of polypore fungi has been noted on the examined area. Among cataloged species, the most popular were: Fomes fomentarius, Piptoporus betulinus, Trichaptum abietinum, Phellinus pini, Ganoderma applanatum, Daedaleopsis confragosa. Rare species of fungi which occur on the red list of endangered and about to become extinct species in Poland include Phellinus pini, and preserved species are Ganoderma lucidum and Inonotus obliquus. Fungi were collected via the “routed” method, from alive and dead trees such as pine trees, birch, black alder and others.
