    Evaluation of some agricultural wastes for the cultivation of edible mushrooms (Pleurotus ostreatus var. salignus)
    (Assn Food Scient Techn India, 2003) Yildiz, A; Karakaplan, M
    Soybean and lentil straw were used as culture media for Pleurotus ostreatus var salignus. As additive substance, 15, 30 and 60 g doses of lentil straw were added to 100 g soybean to obtain different rates in the culture medium. The N% in composite dry weight were 0.5 for control group and 0.60, 0.75 and,0.92 in 15, 30 and 60 g doses of lentil straw, respectively. The effect of different doses of lentil straw on harvesting time was not statistically significant as to control group (p<0.05). The first and total shortest harvesting period in 60 g dose was obtained in 28.5 and 60.4 days, respectively. The highest total fresh yield per 1000 g of material (70% moisture) was 247.5 g in 15 g dose, while the lowest yield was 209.5 g in control group. The dry weight of the product obtained in the experimental group was found to be 10%. The % protein contents (N x 6.25) were 31.68 for control and 31.25, 51.87 and 46.87 for 15, 30 and 60 g doses, respectively.

    An experimental study on mycelial development period of some Pleurotus species, P-ostreatus, P-sapidus and P-sajor-caju, on the media that contain certain amount of barley crumb or wheat flour.
    (Mbr Press Inc, 1998) Akbayin, H; Yildiz, A; Ertekin, AS
    Cultivation of Pleurotus species as mushroom is becoming important throughout the world because of their abilities to grow in a wide range of temperatures, on various types of medium and their shorter cultivation time. The purpose of this study is to determine whether the media that contain 1% malt extract and 1%, 1.5% or 2% wheat flour or barley crumb significantly decrease the mycelium development period of Pleurotus species, P. ostreatus, P. sapidus and P. sajor-caju, compared with the media that merely contains 1% malt extract and to establish which media is more appropriate to produce mycelia of these species vegetatively. As a result, of this study, the media that contain 1% barley crumb and 1% malt extract for P. ostreatus, 1.5% barley crumb and 1% malt extract for P. sapidus, and 1.5% barley crumb and 1% malt extract for P. sajor-caju has been suggested.

    Growth of mycelium of Pleurotus spp. on different grains and determination of their competition with some contaminant fungi
    (Akademiai Kiado Zrt, 2004) Sagir, A; Yildiz, A
    Five mushroom species, P. ostreatus, P. ostreatus var. salignus, P. eryngii, P. florida, P. sajor-caju, three contaminant fungi A. niger, P. italicum, R. stonolifera, and barley, sorghum and wheat grains were used in the study. The purpose of this work was to determine mycelial growth of Pleurotus spp. and their competition with contaminant fungi. The Pleurotus spp. were grown better on the sorghum grains than the barley and wheat grains according to mycelial growth and density. The colony growth of Pleurotus spp. was inhibited by A. niger, P. italicum and R. stonolifera by 13.84%, -1.58% and 24.48%; 9.84%, 20.31% and 18.06%; 14.48%, 100.00% and 100.00% on the 3rd, 5th and 7th days after inoculation, respectively. The mushrooms were completely suppressed by R. stonolifera on the 5th day.

    Level of heavy metals in some edible and poisonous macrofungi from Batman of South East Anatolia, Turkey
    (Triveni Enterprises, 2004) Yesil, ÖF; Yildiz, A; Yavuz, Ö
    The macrofungi specimens were collected and identified from locations around Batman province of Turkey. A group of 21 macrofungi were collected from 29 different locations and analysed for the heavy metal contents. The highest Pb and Cu levels were found in Russula rubroalba while the highest Cd level was determined for the species Agaricus xanthodermus. Fe level was maximum for the species Funalia trogii; Mn for Mycena personsii; Zn level was for Morchella esculenta and Co level was for the species Agaricus xanthodermus. The lowest Cd, Cu, Mn and Zn contents were found in Inotus hispidus.

    Organic elements and protein in some macrofungi of south east Anatolia in Turkey
    (Elsevier Sci Ltd, 2005) Yildiz, A; Yesil, MF; Yavuz, Ö; Karakaplan, M
    The macrofungi specimens were collected from locations around Diyarbakir and Batman. Thirty five species of macrofungi were identified as belonging to 15 families in Diyarbakir and Batman provinces. Protein contents of Boletus luteus, Armillaria tabescens, Helvella sp., Agaricus bisporus, Agrocybe aegerita and Tricholoma ustale were 8.2-18.1, 7.2-10.6, 2.15-27.7, 26.5-51.2, 41.0-46.8, and 29.7-50.5 (% dry weight), respectively. The highest protein concentrations (% dry weight) were found to be in Agaricus bisporus (51.2) which was collected at the Campus of Dicle University and T ustale (50.5) at the Gercus district in Yolagzi village. In conclusion, protein contents, and organic elements were found to be changeable according to growth region and species. (C) 2004 Elsevier Ltd. All rights reserved.

    Studies on Pleurotus ostreatus (Jacq, ex Fr.) Kum. var. salignus (Pers. ex Fr.) Konr. et Maubl.
    (Elsevier Sci Ltd, 1998) Yildiz, A; Karakaplan, M; Aydin, F
    This study was conducted on the growth and cultivation of Pleurotus ostreatus var. salignus on local cellulosic wastes. The highest and lowest yields for 100 g material (70% moisture) were obtained with peanut straw (24.8 g) and with sorghum straw (11.3 g), respectively. Protein, pilus/stip, sporophore weight, % dry material, N and C in highest amounts were obtained with peanut straw. The lowest mushroom weight and pilus/stip ratio were obtained with sorghum, whereas the lowest protein, N and dry material weight were obtained with wheat straw. In all the P. ostreatus var. salignus cultivated on peanut and sorghum straw, the most abundant nutrients were protein, potassium and carbon. These results are discussed in relation to the prospect of cultivating P. ostreatus var. salignus in Diyarbakir, Turkey. (C) 1998 Published by Elsevier Science Ltd. All rights reserved.
