    Opis:
    In this research sawdust samples of Ecalyptus globulus and Cupressus lusitanica were evaluated for bioethanol productions. The sawdust samples were first pretreated with three white rot fungi alone and also by combining the white rot fungi with mild NaOH and steam. Both the fungal and combined pretreated samples were then hydrolyzed with hydrolytic enzymes from three cellulolytic wood rot fungi. Finally, the resulting sugars were fermented into bioethanol using S. cerevisae in anaerobic conditions. Results obtained, in general, indicated that bioethanol amount produced in all cases of sawdust management was significantly higher than the amount obtained from the un-pretreated sawdust samples (p<0.05). In both fungal alone and combined pretreated sawdust samples, higher ethanol yield was obtained from E. globulus than from C. lusitanica. Similarly, combination with NaOH showed better bioethanol yield over combination with steam. The highest alcohol concentration was obtained when pretreated NaOH-006-2G and hydrolyzed with enzymes from 033-1G and followed by results when pretreated with 005-1G and 003-2G, respectively, and hydrolyzed with enzymes from 033-1G.

    Opis:
    In 31 oldest pine stands situated in central and eastern Poland the age within one stand ranged between 8 and 155, on average 10−40 years. These were the stands characterised with the continuity of the regeneration process, but also two−generation stands in which the generation gap between the two generations was 60−120 years. Multi−generation stands were uncommon and the regeneration process had a „wavy pattern”. The likelihood of wood rot occurrence in trees at the age of 200 years as calculated on the basis of a 690−tree sample (age between 84 and 235 years) is 60% on average, and on more fertile sites it exceeds 70%.

    Opis:
    The European spruce bark beetle (Ips typographus) outbreak observed in the ‘Puszcza Białowieska’ Promotional Forest Complex since 2012 resulted in a total volume of 1.4 million m3 of dead trees in multiple spruce stands. The study aimed to assess the species composition of fungi occurring in spruce trunks at early stages of European spruce bark beetle attack. All the samples used in laboratory analyses were collected in 2016 and 2017 in Białowieża, Browsk, and Hajnówka forest districts. A total of 60 dying spruces selected at random were sampled providing 120 samples. Surface−sterilised samples were used in fungal isolations using malt extract agar medium. The resulting colonies were identified morphologically, additional molecular identification was carried out for representatives of morphotypes using ITS rDNA fragment. In addition to these analyses, the frequently occurring basidiomycete fungi on recently died spruce trees were identified based on the morphology of fruiting bodies. One of the most common symptoms observed on trunks of spruces at the early stages of dieback was the occurrence of sapstains starting from bark beetle galleries. In some trunks the stained wood sections were separated by rusty−red stripes. A total of 51 fungal species including 40 ascomycetes and 11 basidiomycetes were isolated from dying spruce trunks. The number of ascomycete species included 16 ophiostomatoid fungi (members of Ophiostomatales and Microascales). The frequently occurring species in this group were: Endoconidiophora polonica (=Ceratocystis polonica) (17.5%), Grosmannia penicillata (20.8%), Ophiostoma brunneolum (9.2%), O. piceae (5.8%) and O. abieticola (4.2%). Among other ascomycetes only three species were frequently isolated: Neonectria fuckeliana (15.0%), Clonostachys rosea (13.3%) and Cosmospora viridescens (9.2%). The rusty−red coloured areas harboured primarily Amylostereum areolatum and Stereum sanguinolentum. The most frequently detected basidiomycete fungus on trunks at the initial stages of dieback was Cylindrobasidium sp. (=Gloeocystidium ipidophilum), whereas Fomitopsis pinicola was the most frequent species on spruce trunks dead for some years, either standing or wind−snapped. We emphasise the potential role of the detected fungi in forest ecosystems of the Białowieża Forest, both as potential tree pathogens and decomposers of spruce debris remaining in the stand.

    Opis:
    Trametes gibbosa is a widespread polypore fungus occurring throughout Europe and Asia. It is considered a saprotroph occasionally exhibiting parasitic activity. The aims of the present experimental work were to: (1) determine the ability of T. gibbosa pure culture to decompose beech wood under laboratory conditions, (2) test the trophic abilities of T. gibbosa by comparative analysis of the development of its mycelium inoculated into the stems of living beech trees and into beech rollers (stem segments – dead substrate). The laboratory wood decay experiment revealed considerable weight loss of the beech wood samples exposed to T. gibbosa (32.7% after 120 days). Identification of the mycelium used for inoculation in natural forest conditions was done by morphological analysis of the cultures and molecular barcoding. Attempts to recover T. gibbosa mycelium were made after two and eight years for the living trees, and after two years for the rollers. While T. gibbosa could not be reisolated from the inoculated beech trees, basidiomata were observed on the beech rollers, and genetically verified T. gibbosa mycelium was extracted from them. We conclude that T. gibbosa exhibits strong saprotrophic inclinations.

    Opis:
    The effect of Phlebiopsis gigantea treatment in control of Heterobasidion parviporum in Norway spruce is less effective than that in control of Heterobasidion annosum in pine. It is necessary to apply other fungi, for example, Pleurotus abieticola in Norway spruce stands. Thus, it is necessary to assess the activity of major ligninolytic enzymes, that is, laccase, lignin peroxidase (LiP), manganese peroxidase (MnP) and versatile peroxidase (VP) produced by P. abieticola, which may be effective in the fast degradation of Norway spruce wood. Three strains of P. abieticola (Pa1-3) were grown on pieces of Norway spruce sapwood and heartwood for 50 days in laboratory conditions. Enzymatic activity was determined using spectrophotometry. Pleurotus abieticola produced laccase, LiP, MnP and VP. The activity of laccase was low, ranging 0–3.696 and 0–0.806 mU/μg of protein in sapwood and heartwood, respectively. The highest activity in Pa1 = 3.696 mU/μg of protein in sapwood and in Pa3 = 0.806 mU/μg of protein in heartwood was observed after 30 and 50 days of incubation, respectively. The activity of LiP was also low, ranging 0–0.188 and 0–0.271 mU/μg of protein in sapwood and heartwood, respectively. The highest activity in Pa1 = 0.271 mU/μg of protein in sapwood and in Pa2 = 0.188 mU/μg of protein in heartwood was observed after 40 and 20 days of incubation, respectively. The activity of MnP ranged 0–17.618 and 0–12.203 mU/μg of protein in sapwood and heartwood, respectively. This enzymatic activity peaked at the 50th day of culture on sapwood for the Pa3 strain (17.618 mU/μg of protein) and at the 20th day of culture on heartwood for the Pa1 strain (12.203 mU/μg of protein). The activity of VP with manganese-oxidising properties was found to be high in all strains of P. abieticola, ranging 0–39.19 and 0–59.153 mU/μg of protein in sapwood and heartwood, respectively, whereas the activity of VP with guaiacol-oxidising properties was very low for all P. abieticola strains, ranging 0–0.248 and 0–0.225 mU/μg of protein in sapwood and heartwood, respectively. The values of released hydroxyphenols in P. abieticola strains ranged 24.915–139.766 and 25.19–84.562 µg of protocatechuic acid/ml in sapwood and heartwood, respectively. The values of released methoxyphenols for the evaluated strains of P. abieticola ranged 7.225–23.789 and 1.953–20.651 µg of vanillic acid/ml in sapwood and heartwood, respectively. Further studies with a higher number of strains of this species as well as an optimisation of conditions for the measurement of ligninolytic activity are needed.

    Opis:
    Black alder is an important forest−forming species in Poland. Its wood is decomposed by many species of fungi. Ganoderma lucidum (Curtis) P. Karst. is a species of Basidiomycetes which belongs to family Ganodermataceae, order Polyporales. This fungus causes white rot decay of wood in dead and sometimes living alder trees. G. lucidum has been under partial protection in Poland since 2014. It is also red−listed as a rare species (category R – taxa with small populations) on the ‘Red list of the macrofungi in Poland’. The fungus was cut out with a sizeable fragment of wood from the alder stump in Łuków Forest District (eastern Poland) and transported to the laboratory of the Department of Mycology and Forest Phytopathology, Warsaw University of Life Sciences−SGGW. Pure culture of G. lucidum mycelium was obtained from a fragment of fruitbody. The aim of this study was to investigate, through laboratory decay tests, the ability of G. lucidum to degrade alder wood. Sterilization of wood samples (30×20×20 mm) consisted of placing the material in an accelerator and irradiating it with high−energy electrons at a dose of 30 kGy at the Institute of Nuclear Chemistry and Technology in Warsaw. On the next day, wood samples were put into 200 ml flasks with mycelium of G. lucidum on agar−wort medium (2 samples per flask). The flasks were placed in a Heraeus BK 600 incubator for 180 days, with a constant temperature of 22°C and humidity of 80 ±5%. Every 30 days 10 flasks were randomly selected, i.e. 20 samples of alder wood from this experiment. After each incubation period the samples were removed from the flasks, cleaned to remove mycelia and dried at a temperature of 105°C until they reached constant weight. By comparing mass of the samples at the start and the end of experiment in an absolutely dry state, the relative wood mass loss was calculated. After exposure times 180 days, the relative weight loss of alder wood as a result of decay by G. lucidum mycelium was on average 10.88%. The rate of the decay was almost constant during the study period. On some alder wood samples structures resembling fruitbodies of G. lucidum were noticed.

    The author briefly provides information on charcoal, wood tar, birch tar, wooden black and potash as well as in other products of wood thermolysis. As early as in the latest period of the Stone Age (i.e. Neolithic) charcoal was used for burning bricks and ceramics, smelting metal ores, thermal processing of metals as well as in goldsmithing. Both charcoal and wood tar had particular importance in the development of military technology, especially flammable materials, black gun powder and therefore, in the origin of fire arms and artillery. Wood tar was also used for sealing watercrafts, roofs and building timber preservation. Birch tar was used medicine and veterinary. Wooden black and potash was also produced by forestry charcoaling.

    The paper describes the results of investigation on the range of trophic abilities and preferences of fungi causing the wood decay of the brown rot pattern. Fomitopsis pinicola, Laetiporus sulphureus, Piptoporus betulinus and Serpula lacrymans fungi were tested. Wooden samples made from wood of 25 different, both European and exotic, tree species were used. They were put on mycelium of every tested fungus. After 30, 60 and 90 days of exposition samples were weighted and the loss of their mass was calculated to compare the differences of wood destroying abilities between examined tree species. The results indicated that the range of trophic abilities in ex situ conditions of tested fungi species was much wider than in nature. All examined fungi were able to decay the wood of more tree species and their trophic preferences occurred to be different as well.

    Opis:
    The wood present in trade in Poland named as ‘Siberian larch’, in fact belongs to two tree species: Larix sibirica Ledeb. and Larix gmelinii (Rupr.) Kuzen. The term itself is rather associated with the origin of wood. While Larix sibirica wood is the subject of many research, characteristics of Larix gmelinii still require additions. The main aim of this paper was to describe the technical properties of Dahurian larch wood. We characterised also the microstructure of the wood. Moreover, durability against fungi−caused brown rot was tested. The wood from the Chabarowsk area (Russia) was tested. The properties of wood were determined in accordance with the recom−mendations of the Polish standards. The obtained results allow to conclude that Dahurian larch wood is characterized by medium shrinkage and typical shrinkage anisotropy (total radial shrinkage was 5.0% and in the tangential direction 7.6%). With the average density of this wood in an air−dry state equal to 620 kg/m3, average mechanical properties are associated – modulus of elasticity 12.5 GPa and Janka hardness on the cross−section of 57 MPa. These values are similar to those of Siberian larch. Dahurian larch heartwoods is characterized by low durability (4th class of natural durability to fungi in a 5−degree scale). It causes that wood used in external environment require special attention and use of wood preservatives.

    Opis:
    Siberian yellow pine (Pinus sibirica Du Tour.) has increasingly appeared in the merchant offers on the market of raw wood materials in Poland. However, the knowledge of the technical characteristics of its wood is still insufficient for it is based primarily on the data and experiences from abroad, often from the literature of the former USSR. The main aim of this study was to determine selected physical and mechanical properties of Siberian yellow pine wood such as linear and volumetric shrinkage, compressive strength along the fibers, the tensile strength along the fibers, the tensile strength across the fibers, static bending and modulus of elasticity, flexural dynamic and impact strength, hardness, resistance to splitting and cleavage amd shear strength. Futhermore, the resistance to decay caused by Coniophora puteana (Schum., Fr.) Karst., as well as the examination of the wood structure, assessing the dimensions and arrangement of the structural elements in particular were conducted. The results show that Siberian yellow pine wood has a number of similarities to Scots pine wood in terms of the structure. The wood is very light, with a density of 391 kg/m3 and very soft (Janka hardness on transverse cross section 23 MPa). The mechanical properties of Siberian yellow pine wood are closely related to its density and much lower when compared with Scots pine. Shear strength equalled to 67 MPa, static bending strength – 65 MPa and compression strength along the fibers – 49 MPa. The durability to brown rot fungus of Siberian pine wood is comparable to Scots pine (3rd class according to PN−EN 350−2:2000).

    Opis:
    The paper describes the results of investigation on the range of trophic abilities and preferences of fungi causing the wood decay of the brown rot pattern. Fomitopsis pinicola, Laetiporus sulphureus, Piptoporus betulinus and Serpula lacrymans fungi were tested. Wooden samples made from wood of 25 different, both European and exotic, tree species were used. They were put on mycelium of every tested fungus. After 30, 60 and 90 days of exposition samples were weighted and the loss of their mass was calculated to compare the differences of wood destroying abilities between examined tree species. The results indicated that the range of trophic abilities in ex situ conditions of tested fungi species was much wider than in nature. All examined fungi were able to decay the wood of more tree species and their trophic preferences occurred to be different as well.
