A checklist is presented concerning the species composition of Hymenomycetes (Aphyllophorales s.l.) and Heterobasidiomycetes in Israel based on data of previous studies and field sample collections. In total, 242 species are presented, of which five are new records for the Israeli mycobiota, namely Australohydnum dregeanum, Ceriporiopsis consobrina, C. resinascens, Fibroporia vaillantii, and Postia inocybe. The distribution and habitat of each species in Israel are also summarized. This checklist will serve as valuable data for future species diversity studies of these fungi in Israel.

The Elfvingia applanata (EA), Hericium erinaceum (HE),Grifola frondosa (GF), Pholiota nameko (PN), Pleurotus eryngii (PE), Trametes suaveolens (TS), Fomes fomentarius (FF), and Inonotus obliquus (IO) could produce the endo- (EN) and exo-biopolymer (EX) in submerged culture. The highest anti-complementary activity of the EN was exhibited by PN (49.1%), followed by HE (38.6%), TS (37.0%),and FF (33.0%),whereas the high activity of the EX was found with GF (59.8%),followed by HE (36.3%),TS (30.8%),and IO (28.8%). The EN of P. nameko (EN-PN) and EX of G. frondosa (EX-GF) were found to contain 78.6% and 41.2% carbohydrates, while 21.4% and 58.8% protein, respectively. The sugar and amino acid compositions of EN-PN and EX-GF were also analyzed in detail.

An unrecorded Ceriporiopsis species was collected at Mt. Gariwang, Gangwon Province, in 2008. Based on morphological characteristics, such as a fully resupinate basidiocarp, a reddish white to pinkish poroid hymenophore and a monomitic hyphal system with clamp connections, the species was identified as Ceriporiopsis resinascens. This is the first report of Ceriporiopsis resinascens in Korea. We confirmed the identity of the species as Ceriporiopsis resinascens based on ITS sequence analysis.

The study of bacteriophage began by F.W. Twort in 1915 and the lytic cycle recognized by d'Herellel in 1917. It repeated about the marine bacteriophage containing Vibrio phage by Smith, Spencer and Ju. Authors isolated 2 virulent phages for the pathogenic V. alginolyticus from marine products. These 2 phages were examined their ultrastructure & host-infection by elecron microscopy and in vivo test using skin of rats. V. alginolyticus phages(VAPs) fomed plaques about 0.5 - 0.9mm in diameter and bands 50 - 60% in sucrose density gradient. VAP had 50 - 120nm tail and 40 - 90nm head in diameter. In vivo test, using rat skin, as well as in vitro test VAP had the activity to V. alginolyticus isolated.

Two phages for the pathogenic V. alginolyticus were isolated from marine products. These 2 phages were examined temperature stability, pH stability, inactivation by UV irradiation, damage on restriction system of host cell, antibody production, structure protein analysis and western blotting assay. V. alginolyticus phages(VAPs) fomed plaques about 0.5 - 0.9mm in diameter and bands 50 - 60% in sucrose density gradient, VAPs were stable below 65'C, pH 5 - 10 and mostly inactivation by UV irradiation for 120sec. Latend period was 15 - 20 min. and burst size was 1.3 - 1.4 * 10 PFU/cell. Restriction system of V. alginolyticus isolated was mostly inactivated by 45C, 20min. heating. VAPs had 14 specific structural proteins and 5 proteins related to antibody production.

Hypoglycemic effects of exo-biopolymers (EBP) produced by submerged mycelial cultures of Coriolus versicolor, Cordyceps sinensis, Paecilomyces japonica, Armillariella mellea, and Fomes fomentarius were investigated in streptozotocin (STZ)-induced diabetic rats. The rats from each experimental group were orally administered with EBPs (100 mg/kg BW) daily for 2 weeks. Though the hypoglycemic effect was achieved in all the cases, however, C. versicolor EBP proved as the most potent one. The administration of the C. versicolor EBP substantially reduced (29.9%) the plasma glucose level as compared to the saline administered group (control). It also reduced the plasma total cholesterol (TC), triglyceride (TG), aspartate aminotransferase (AST) and, alanine aminotransferase (ALT) levels by 9.22, 23.83, 16.93, and 27.31%, respectively. The sugar and amino acid compositions of this EBP were also analyzed in detail.

The polypore genus Abundisporus Ryvarden is characterized by resupinate to pileate fruitbodies with a purplish brown hymenophore, slightly thick-walled, pale yellowish and non-dextrinoid basidiospores, and causing white rot. A purple color hymenophore, an easily observable and striking character, was considered the main distinctive feature at the generic level within polypores. However, due to highly similar basidiocarp features, species identification within these purple polypores is particularly difficult. Three species of purple colored polypores have been reported in Korea (Abundisporus fuscopurpureus, A. pubertatis, and Fomitopsis rosea). Based on morphological re-examination, ecological information, and sequence analysis of the internal transcribed spacer, we showed that previous classification was incorrect and there is only one species (A. pubertatis) in Korea. We provide a detailed description of A. pubertatis in Korea, as well as a taxonomic key to distinguish wood rot fungi with a purple hymenophore.

beta-Glucosidase, which hydrolyzes cellobiose into two glucoses, plays an important role in the process of saccharification of the lignocellulosic biomass. In this study, we optimized the activity of beta-glucosidase of brown-rot fungus Fomitopsis pinicola KCTC 6208 using the response surface methodology (RSM) with various concentrations of glucose, yeast extract and ascorbic acid, which are the most significant nutrients for activity of beta-glucosidase. The highest activity of beta-glucosidase was achieved 3.02% of glucose, 4.35% of yeast extract, and 7.41% ascorbic acid where ascorbic acid was most effective. The maximum activity of beta-glucosidase predicted by the RSM was 15.34 U/mg, which was similar to the experimental value 14.90 U/mg at the 16th day of incubation. This optimized activity of beta-glucosidase was 23.6 times higher than the preliminary activity value, 0.63 U/mg, and was also much higher than previous values reported in other fungi strains. Therefore, a simplified medium supplemented with a cheap vitamin source, such as ascorbic acid, could be a cost effective mean of increasing beta-glucosidase activity.

Polyporoid and corticioid fungi are among the most important wood-decay fungi. Not only do they contribute to nutrient cycling by decomposing wood debris, but they are also valuable sources for natural products. Polyporoid and corticioid wood-inhabiting fungi were investigated in Odaesan National Park. Fruit bodies were collected and identified based on morphological and molecular analyses using 28S and internal transcribed spacer regions of DNA sequences. As a result, a total of 149 species, 69 genera, 22 families, and 11 orders were recognized. Half (74 species) of the species were polypores, and the other half (75 species) were corticioid fungi. Most of the species belonged to Polyporales (92 species) followed by Hymenochaetales (33 species) and Russulales (11 species). At the genus level, a high number of species was observed from Steccherinum, Hyphodontia, Phanerochaete, Postia, and Trametes. Concerning distribution, almost all the species could be found below 1,000 m, and only 20% of the species were observed from above 1,000 m. Stereum subtomentosum, Trametes versicolor, T. hirsuta, T. pubescens, Bjerkandera adusta, and Ganoderma applanatum had wide distribution areas. Deciduous wood was the preferred substrate for the collected species. Sixty-three species were new to this region, and 21 species were new to Korea, of which 17 species were described and illustrated.
