10.1615/IntJMedMushr.v9.i34.10
On September 23−27, 2007, the Fourth International Medicinal Mushroom Conference was held in Ljubljana, Slovenia. Three hundred scientists from 46 countries, from all continents, presented their results in abstracts published in this special issue of the IJMM. About 800 scientists are the authors of these published abstracts.
The conference plenary lectures, parallel sessions, and poster presentations covered a wide array of topics including systematics, taxonomy, distribution, ecology, fungal culture collections, medicinal value, and pharmacology of mushroom active compounds, mushroom nutraceuticals, fungal physiology, biochemistry and genetics, mycotechnology and cultivation, mycoremediation, ethnomycology, folk medicine, and homeopathy using medicinal mushrooms. Special scientific topics were dedicated to species of the genera Cordyceps, Canoderma, Grifola, Phellinus, Pleurotus, and Trametes. Among the participants, you will recognize the names of many well known experts in culinary-medicinal mushrooms.
The conference was organized by University of Ljubljana and Slovenian Association of Mushroom Cultivation. The sponsors of the conference were Fungi Perfecti (USA), Perutnina Ptuj d.d. (Slovenia), Slovenian Research Agency, and International Society of Mushroom Science.
I would like to thank all organizers of this very important meeting, including the participants who presented lectures, oral presentations, posters, and abstracts, and to the sponsors (to whom we are extremely grateful, because without their support this conference could not have been held).
The Fifth International Medicinal Mushroom Conference will be held August 2−7, 2009, in Chang-Chun city in P.R. China. The Chinese Mycology Society (President Professor Yu Li) will be the main organizer of the conference. China Chamber of Commerce of Import and Export of Foodstuffs, Native Produce & Animal By-Products (CFNA), China Edible Fungi Association (CEFA), and Jiangsu Anhui Bio-tech Co., Ltd. will be the main supporters and sponsors for this conference.

The purpose of this research was to evaluate the productiveness, biological efficiency, and fresh and dry biomass of Pleurotus spp. cultivated in elephant-grass-based substrate. Three species of Pleurotus were used: Pleurotus ostreatus (strains BF24 and DF33), P. ostreatoroseus (strain POR01/06), and P. citrinopileatus (strain PAM01/06). Dry and powdered elephant grass was humidified for 24 hours, wrapped in bags, pasteurized at 100°C for 35 minutes, and finally inoculated with 3% spawn. The cultivation period extended for 105 days, encompassing 3 production flushes, and the beginning of the harvest was 25 days after substrate inoculation. P. ostreatoroseus presented the highest productiveness rates (33.16%), biological efficiency (132.64%), and fresh mass (331.60 g); the P. ostreatus strain BF24 presented the highest dry mass rate (31.16 g).

The presence of macro- and microelements in 16 Phellinus species were estimated by atomic absorption spectroscopy, and the content of 14 elements were analyzed. Compared to other elements, the calcium content was significant (1000−1100 ppm), followed by sodium (8−17 ppm). The overall ranking of elements for most of the samples was established as Ca > Na > Mg > Fe > Ge > Zn > Mn > Se > Cu > Cr. During the present investigation, toxic elements such as lead, cadmium, arsenic, and cobalt were not detected, but important medical elements, such as germanium and selenium, were detected (0.2−0.5 ppm and 0.1−0.5 ppm, respectively). This is the first report of the presence of germanium and selenium in Indian Phellinus species. Compared with Indian Food Processing Organization (FPO) data, toxic elements in Phellinus species were either absent or in very low amounts, indicating the nontoxicity of the samples. The data suggest that the Indian Phellinus species might be safe to consume as a nutraceutical without posing any serious risk to humans.

The present study is based on the mycelial growth of 37 Pleurotus strains, belonging to P. djamor, P. ostreatus, and P. pulmonarius species. The strains were grown on sugarcane bagasse, using 2 kinds of inoculation: (1) spawn prepared on wheat seeds, and (2) mycelium grown within solid water-agar culture with no nutrients added. Based on differences found in the mycelial growth, 6 strains were selected to determine the production of certain hydrolytic and oxidative enzymes throughout the full growth cycle at 0, 4, 8, 12, and 16 days (incubation period), also including the primordia formation, fruiting, and postharvest stages. The production of laccase and Mn-peroxidase was clear during the incubation stage, decreased during the fruiting stage, and increased again during the postharvest stage. In addition, the production of cellulases, cellobiohydrolases, and xylanases was low during the incubation period, increased during the production of fruiting bodies, and declined during the postharvest. There was a visible inverse correlation between the content of soluble phenols of the substrate and the laccase production at 8 (r = −.85) and 12 (r = −.92) incubation days. The incubation period varied between 12 and 45 days among the studied strains. Their biological efficiency was generally good, with values between 65.3% and 118.8%.
