A laboratory experiment was conductedto determine the ability of Phanerochaetechrysosporium, Ceriporiopsis subvermispora,and Pleurocybella porrigens and seven white-rot fungi isolated from a native of tropicalenvironment to grow on yeast malt extractglucose (YMG) agar containing highconcentration of (I) 2,4-dichlorophenoxy aceticacid, (R) glyphosate, and (G) paraquat. Thedata indicated that P. chrysosporium couldgrow on YMG media containing 5000 ppm of(I) 2,4-D, whereas BPBPI 02/04 isolate onYMG 250 ppm of (R) glyphosate or (G)paraquat. Relative values of growth inhibitionof these fungi are 81.1; 27.8; and 50.0%respectively.

Wood Decay Fungi

Influences of eight saturated aliphatic acids (C5–C10, C12, and C16) on basidiospores of four isolates of wood-decay fungi (Poria tenuis and Trametes hispida, white rot fungi, and two isolates of the brown rot fungus Gloeophyllum trabeum) were observed in vitro. Spore responses after 24 h on malt extract agar containing 10, 102 or 103 ppm of each acid included normal germination, delay of germ tube emergence, vacuolation and degeneration of spore cytoplasm, and prevention of germ tube development without spore destruction. Acids of chain length C5–C10 prevented spore germination and killed spores of all fungi at concentrations of 20–50 ppm in media, whereas other acids tested were less active. Spore germination assay of decay fungi may prove useful as a screening tool to compare potency of wood preservatives.

White rot fungi were able to mineralize the aromatic ring carbon of alachlor to CO2. After 122 days, 14 and 12% of the alachlor that was initially present in malt extract cultures supplemented with a wood substrate was mineralized at room temperature by Ceriporiopsis subvermispora and Phlebia tremellosa, respectively. Although Phanerochaete chrysosporium mineralized alachlor at 25 °C, it did so more slowly than the other two white rot fungi. The brown rot fungus Fomitopsis pinicola did not mineralize alachlor.Key words: alachlor, mineralization, white rot fungi, pesticide.

Fibre Analysis

Five isolates of wood-rotting fungi were compared for their ability to increase the digestibility of poplar shavings. Homogenates of the fungi were inoculated into mixtures of 25 g of shavings and 100 mL of supplementary nutrient solution and incubated at 25 °C. The in vitro rumen digestibility of the products increased from 30% at the start of the fermentation to maxima of 72% with Polyporus anceps after 8 weeks, 64% with Ganoderma applanatum and 62% with Phanerochaete chrysosporium after 4 weeks, 61% with Polyporus versicolor after 3 weeks, and 42% with Fomitopsis ulmarius after 4 weeks. Fibre analysis showed a decrease in lignin as digestibility increased. Loss of carbohydrates occurred in all fermentations and continued after lignin loss ceased. Dry matter yield at the time of maximum digestibility ranged from 80 to 94% of the original dry matter. The highest digestibilities attained were similar to those of conventional roughage feeds for ruminants. This shows that this fermentation could form the basis of a practical system for converting poplar into a feedstuff.

The influence of rice straw fermentation using white rot fungi and saccharomyces cerevisiae supplementation on in vitro nutrient digestibilityABSTRACT. An experiment to investigate the effect of rice straw fermented using white rot fungi and Saccharomyces cerevisiae supplementation on nutrient digestibility In Vitro had been implemented in two phases. The first experiments undertaken to make rice straw fermentation, using experimental methods with a Completely Randomized Design. As the treatment were White rot fungi (Phanerochaete chrysosporium) 0, 5 and 10 g/kg of rice straw (DM basis). Each treatment was repeated six times, so there are 18 experimental units. The variables measured included nutrient content of rice straw. A second experiment carried out in vitro to test the best rice straw fermentation results of the first experiment, using experimental methods, with a Completely Randomized Design. As the treatment were the supplementation of Saccharomyces cerevisiae (0, 2, 4% of the weight of fermented rice straw, DM basis). The variables measured included digestibility of dry matter, organic matter, cellulose and lignin digestibility of feed containing fermented straw. The data obtained were analyzed using analysis of variance test followed by Orthogonal Polynomials. The results can be concluded that the fermented rice straw using Phanerochaete chrysosporium 10 g/kg of rice straw is the best nutrient content. Saccharomyces cerevisiae supplementation on feed that contains fermented rice straw using Phanerochaete chrysosporium 10 g/kg rice straw is 2%.

The in vitro wood decay abilities of Ganoderma lucidum (W. Curt.: Fr.) Karst. and G. tsugae Murr. were studied using the following woods in agar block decay chambers: Vitis vinifera L., Quercus hypoleucoides A. Camus, Prosopis velutina Woot., Abies concolor (Gord. & Glend.) Lindl. ex. Hildebr., and Pseudotsuga menziesii (Mirb.) Franco. Grape wood lost the most weight while mesquite the least. Ganoderma lucidum isolates generally caused greater weight loss of all woods than did G. tsugae isolates. The range of the percent weight losses varied with the wood. Both Ganoderma species caused simultaneous decay in all woods. However, chemical analyses of the decayed blocks indicated that selective delignification by both species also occurred in grape and white fir blocks. Chemical analysis of the decayed oak blocks indicated the percentages of lignin and holocellulose were not statistically different from the controls. However, there was a trend towards delignification. The analyses of the Douglas-fir blocks indicated only simultaneous decay. Scanning electron microscopy demonstrated selective delignification and simultaneous decay of all woods tested. However, the extent of the delignification differed among the wood species. Delignification appeared mainly in areas of tracheids or fiber tracheids, while the rays were simultaneously decayed.

Control Of Expression

Genetics provides an approach to the analysis of the complex function of lignin biodegradation, through the isolation of mutants and the creation of gene libraries for the identification of genes and their products. However, white-rot fungi (for example, Phanerochaete chrysosporium ) have not so far been analysed from this point of view, and there is the challenge of establishing such genetics. P. chrysosporium is convenient experimentally because relatively few genes are switched on at the onset of ligninolytic activity. We describe the isolation of clones carrying genes expressed specifically in the ligninolytic phase, the development of a general strategy for mapping such clones, and the elucidation of the mating system of this organism. Another objective is the development of methods for transforming DNA into P. chrysosporium . This would allow the use of site-directed mutagenesis to analyse the functioning of ligninases, and the control of expression of the corresponding genes. The use of genetic crosses for strain improvement and the identification of components of the system are also discussed.

Biological de-lignification of straw by white-rot fungi seems a promising way of improving its nutritive value. The bio-conversion of lignocellulosic materials is circumscribed to the group of white-rot fungi, of which some species of Pleurotus are capable of producing upgraded spent-straws as ruminant feed (Fazaeli et al., 2004). Treating of cereal straw with white-rot fungi as animal feed was studied by several workers (Gupta et al., 1993; Zadrazil, 1997). However, most of the trials were conducted at in vitro stage and used cell wall degradation and in vitro digestibility as an index to evaluate the biological treatments. This experiment was conducted to study the effect of fungal treatment on the voluntary intake, in vivo digestibility and nutritive value index of wheat straw obtained from short-term and long-term solid state fermentation (SSF).
