The fungus Agaricus bisporus is commercially grown for the production of edible mushrooms. This cultivation occurs on compost, but not all of this substrate is consumed by the fungus. To determine why certain fractions remain unused, carbohydrate degrading enzymes, water-extracted from mushroom-grown compost at different stages of mycelium growth and fruiting body formation, were analyzed for t...

Two cases of an acute chest illness occurring in mushroom workers are described. In one patient, who was severely ill, a lung biopsy was obtained which showed a pattern of alveolitis and interstitial fibrosis. The serum of both patients gave a precipitin reaction to an extraction of mushroom compost after spawning, but no reaction occurred to a variety of hay antigens used in the diagnosis of f...

BACKGROUND One of the most important environmental problems is the decontamination of petroleum hydrocarbons polluted soil, particularly in the oil-rich country. Bioremediation is the most effective way to remove these pollutants in the soil. Spent mushroom compost has great ability to decompose lignin-like pollution. The purpose of this study was the bioremediation of soil contaminated with cr...

The effects of adding of a range of organic amendments (biosolids, spent mushroom compost, green waste compost and green waste-derived biochar), at two rates, on some key chemical, physical and microbial properties of bauxite processing sand were studied in a laboratory incubation study. Addition of all amendments tended to decrease bulk density and macroporosity but increase total porosity, av...

A total of 400 samples were collected from different thermogenic habitats such as nests of birds, decomposing litter, soils from furnace area, cattle dung, zoo dump, industrial waste, vegetable market compost, mushroom compost, horse dung, municipal waste, chicken manure and coal mine soils of Godavari Khani (Karimnagar) and Bhoopalpally (Warangal) group of mines in Andhra Pradesh. From which 4...

abstract edible white button mushroom is a secondary decomposer and the activity of other micro-organisms is necessary to decompose the raw compounds for its growth. actinomycetes bacteria due to their ability to decompose the compound molecules such as cellulose, lingo-cellulose and lignin, play an important role in the composting process for the mushroom. bacterial biomass of actinomycetes co...

consumption of organic manures such as vermicompost and spent mushroom compost in a system based on organic agriculture beside to maintenance soil health improvement and yield of medicinal plant spearmint. therefore, an completely randomized design experiment with four replication on spearmint (mentha spicata l )was conducted in horticultural department of mohaghegh ardabili university. experim...

Supplementation of mushroom compost at spawning and at casing with various refined and crude seed oils resulted in 1 to 1.5 lb/ft increases in mushroom yield. Supplementation at casing with ground seeds or protein-oil combinations caused 2 to 2.5 lb/ft increases in mushroom yield. Further evidence is presented for a relationship between lipid metabolism and the initiation of fruiting in the cul...

in recent years the use of organic and biological modifier as an environmental friendly replacement for chemical fertilizers has been used more. in order to study the effect of different levels of biological fertilizers and mushroom compost on flower yield and characteristics of saffron corms (crocus sativus l.), a split plot experiment based on rcbd design with three replications was conducted...

one of the most important steps of agaricus bisporus production is casing. in this step a layer of soil is added on top of compost. peat is the most suitable casing soil for a. bisporus production. the lack of peat in iran is one of the major problems in a. bisporus production for mushroom producers. it seems that peat can be replaced by spent mushroom compost (smc). in order to study the possi...
