Cultivation of Pleurotus tuber-regium (Fr) Sing on Various Farm Wastes

Various farm wastes were investigated as substrates for Pleurotus tuber-regium. The highest mushroom harvest (fresh weight) was obtained from oil palm fruit fiber substrate and the lowest yield was from yam (Dioscorea sp.) peelings. Casing enhanced yield from all substrates. Oil palm fruit fiber spawn is an alternative to the sclerotium in propagating the fungus. Some fungi and pests were assoc...

Biodegradation of agro-industrial wastes by a edible mushroom Pleurotus tuber-regium (Fr.).

When Pleurotus tuber-regium was cultivated on cotton waste, rice straw, cocoyam peels and sawdusts of Mansonia altissima, Boscia angustifolia and Khaya ivorensis, the highest crude protein, crude fat and carbohydrate contents in sporophores were 29.4 (M. altissima) , 1.4 (rice straw) and 61.3% (cocoyam peels), respectively. Sporophores produced on rice straw had the greatest energy value and th...

The HST view of the FR I / FR II dichotomy ⋆

In order to explore how the FR I / FR II dichotomy is related to the nuclear properties of radio galaxies, we studied a complete sample of 26 nearby FR II radio galaxies using Hubble Space Telescope (HST) images and compared them with a sample of FR I previously analyzed. FR I nuclei lie in the radio-optical luminosity plane along a tight linear correlation, which argues for a common synchrotro...

Multi-Residue Analysis of Pesticides in Pistachio Using Gas Chromatography-Mass Spectrometry (GC/MS)

Background: Analysis of pesticide residues in food and other environmental commodities have become an essential requirement for consumers, producers, food inspectors and authorities. This study is focused on validation of an accurate, rapid and reliable method for multi-residual analysis of pesticides in pistachio as a strategic crop for export and one of the main nuts in Iranian food basket.Me...
