The aim of the research was to examine the antifungal activity and the most effective concentration of teak bark (Tectona grandis Linn F) extract in inhibiting wood decay fungi Schizophyllum commune Fries. Teak bark was derived from BKPH Ledok, Sambong district, Blora Regency, West Java. The Teak bark made into particle with size pass of 40 mesh and retained 60 mesh. Then one kilogram of teak bark particle was maceration with 10 liter of aquadest. The extract then mixes with potatoes dextrose agar (PDA) with several concentration i.e. 0%, 0.25%, 0.5%, 0.75% and 1% and pour into petri dish. One isolate of Schizophyllum commune was put in the center of PDA in each petri dish then incubated for nine days. The bioactive compound of extract teak bark was evaluation used phytochemical screening. Result of the research showed that teak bark extract at concentration 0.25% and 0.5% has antifungal activity values was 27.98% and 40.38% and categorized as medium inhibition growth of S. commune. Meanwhile at concentration 0.75% and 1% the AFA values was 59.94% and 65.51% categorized as strong inhibition growth of S. commune. The bioactive compounds from phytochemical screening test were alkaloid, flavonoid, terpenoid, fenolik, antrakuinon, and saponin. The extract of teak bark with concentration 0.75% and 1% are the most effective concentrations in inhibiting the growth of wood decay fungi S. commune Fries.Keywords : antifungal, phytochemical screening test, Schizophyllum commune, Tectona grandis

Abstract Cadinane-type sesquiterpenes have a wide spectrum of biological activity, but their use as wood preservatives and the structure-activity relationships of their derivatives have not yet been reported. A total of 13 compounds were synthesized from T-cadinol, T-muurolol, and α-cadinol and their chemical structures were confirmed by IR, MS, and 1H and 13C NMR. The antifungal properties of 16 compounds against three wood-decay fungi were evaluated in vitro. α-Cadinol showed strong antifungal activity against Lenzites betulina, Trametes versicolor, and Laetiporus sulphureus (total mean IC50 0.10 mM). Among the derivatives synthesized, 3β-ethoxy-T-muurolol (0.24 mM), 4ξH-cadinan-10β-ol (0.25 mM), 4ξH-muurolan-10β-ol (0.29 mM), and 4ξH-cadinan-10α-ol (0.25 mM) showed good antifungal activity against all fungi tested. Correlation was observed between the antifungal activity of the compounds tested and log P. Furthermore, the presence of an unsaturated double bond and oxygen-containing functional groups in the compounds plays a key role in their antifungal activity. The stereo configuration of cadinane-type sesquiterpenes also influences their antifungal activity. Understanding how the structure of natural compounds relates to their antifungal function is important and may facilitate their application as novel wood preservatives.

Reference Samples

Abstract The chemical composition of the essential oil of Chamaecyparis formosensis wood has been examined. GC-MS data and retention indices for reference samples were used to identify 32 constituents. α-Eudesmol (18.06%), β-guaiene (8.0%), (–)-β-cadinene (7.89%), γ-costal (7.03%), α-muurolol (6.49%), 4α-hydroxy-4β-methyldihydrocostol (5.52%), σ-selinene (4.78%), santolina triene (4.60%), eremophilene (4.32%), humulene (4.11%), myrtenol (4.11%), and τ-cadinene (3.25%) were the most abundant components. Tests with the typical wood decay fungi, Laetiporus sulphureus and Trametes versicolor, proved the antifungal activity of the oil, as the growth of L. sulphureus and T. versicolor was inhibited at concentrations of 50 and 100 μg ml−1, respectively. The following characteristic volatile compounds were isolated and purified from ethyl acetate fractions: epi-cubenol, chamaecynone, myrtenol, cis-myrtanol, 12-hydroxyisointermedenol and 4α-hydroxy-4β-methyldi-hydrocostol. Chamaecynone possessed the strongest antifungal activity, with an antifungal index of 88.2% and 67.3% for L. sulphureus and T. versicolor at a dose of 50 μg ml−1, respectively.

Abstract Microorganism-based biological protections are alternatives to chemical treatments. Worldwide, Fusarium species are important plant pathogens, and their mycotoxins are antimicrobial. In this study, 18 Fusarium strains isolated in Korea have been investigated. Nine Fusarium species, including two unknown species, were identified based on their genotypic characteristics. Among the identified species, Fusarium armeniacum and Fusarium commune were observed for the first time in Korea. The antifungal activity of Fusarium crude extracts was assessed by growth inhibition against two wood-decay fungi and three sapstain fungi. Most Fusarium strain extracts revealed strong antifungal activity against wood-decay fungi. Strains of the unknown Fusarium sp. 2, which was found in wood samples, showed strong antifungal activity against all wood-decay and sapstain fungi tested in this study.

Wood is a habitat for a variety of organisms, including saprophytic fungi and bacteria, playing an important role in wood decomposition. Wood inhabiting fungi release a diversity of volatiles used as signaling compounds to attract or repel other organisms. Here, we show that volatiles of Schizophyllum commune are active against wood-decay fungi and bacteria found in its mycosphere. We identified sesquiterpenes as the biologically active compounds, that inhibit fungal growth and modify bacterial motility. The low number of cultivable wood inhabiting bacteria prompted us to analyze the microbial community in the mycosphere of S. commune using a culture-independent approach. Most bacteria belong to Actinobacteria and Proteobacteria, including Pseudomonadaceae, Sphingomonadaceae, Erwiniaceae, Yersiniaceae and Mariprofundacea as the dominating families. In the fungal community, the phyla of ascomycetes and basidiomycetes were well represented. We propose that fungal volatiles might have an important function in the wood mycosphere and could meditate interactions between microorganisms across domains and within the fungal kingdom.

Degradation Ability

Aim: The present study was undertaken to provide basic knowledge about the teak woody biomass degradation ability of wood decay fungi. Methodology: Wood decay fungi was isolated from the decayed wood samples collected from teak wood logs. The weight loss of teak wood and moisture content were assessed under in-vitro condition by incubating the teak wood block with the isolated fungi. Further, the secretion of ligninolytic enzymes viz., laccase, lignin peroxidise (LiP) and manganese peroxidase (MnP) produced by wood decay fungi were assessed to understand their degrading ability. Results: Wood decay fungi namely, Daldinia concentrica, Ganoderma lucidum, Lenzites betulina, Ganoderma tsugae, Trametes versicolor and Schizophyllum commune, were isolated from teak wood logs as pure culture and were used for studying their degrading ability. Higher degrading percentage of 10.50 and 12.0 was recorded with L. betulina and T. versicolor inoculated wood blocks on 60th day of incubation. Similarly, the maximum moisture content of 54.45 and 50.00 percent was recorded with L. betulina and T. versicolor at 60th day of incubation in teak wood blocks. Supporting these results, L. betulina showed increased secretion of laccase, LiP and MnP enzyme activity to the level of 0.60, 0.056 and 0.26U ml-1, respectively. Interpretation: The results of the present study gives an understanding on the degrading ability of wood decay fungi which can be used to devise integrated management practices to minimise the losses under storage.

First Time

Fungi may cause internal decay, cankers, loosening of tissue and cell walls result into weak forks in the trunk and large branches. Tree rot may be associated with root decay, damage to foliage and fruits. Wood decay fungi isolated from Tamarindus indica were Daldinia concentrica, Schizophyllum commune, Flavodon flavus,Irpex hydnoides, and Phellinus fastuosus, in which D. concentrica causing canker rot is reported for the first time from India and F. flavus and I. hydnoidesP. fastuosus are recorded for the first time on T. indica wood causing white rot. During canker rot, formation of bark canker and extensive internal decay of wood was observed; as a result the tree growing in the M.S. University campus became structurally unstable and broken off at the canker face. Early detection and removal of such hazardous branches of trees is advocated to avoid loss of life and property.
