Pilot-scale field-testing of passive bioreactors was performed to evaluate the efficiency of a mixture of four substrates (cow manure compost, mushroom compost, sawdust, and rice straw) relative to mushroom compost alone, and of the effect of the Fe/Mn ratio, during the treatment of acid mine drainage (AMD) over a 174-day period. Three 141 L columns, filled with either mushroom compost or the f...

The aim of this study was to determine the chemical composition of stem and compost of the button mushroom to estimate metabolizable energy (ME) and net energy of lactation (NEl) using gas production method and to determine the amount of dry matter disappearance (DMD) using in vitro technique. This study was conducted in a completely randomized design with three treatments o...

We previously showed that the females of the mushroom sciarid, Lycoriella ingenua (Dufour, 1839) (Diptera: Sciaridae), one of the most severe pests of the cultivated white button mushroom, Agaricus bisporus (J.E. Lange) Emil J. Imbach (Agaricales: Agaricaceae), are attracted to the mushroom compost that mushrooms are grown on and not to the mushrooms themselves. We also showed that females are ...

Fresh mushroom compost is a byproduct of the edible mushroom (Agaricus bisporus) industry and represents the composted growing substrate that remains after a crop has been harvested to completion. Thirty samples were obtained from commercial mushroom farms in southeastern Pennsylvania and sent to a laboratory for analysis to determine plant nutrient content, bulk density, and particle size dist...

Hypersensitivity pneumonitis has been described in mushrooms workers caused by exposure to mushroom or fungal spores in the compost used to grow mushrooms. We describe two mushroom workers who developed hypersensitivity pneumonitis due to exposure to avian proteins found in poultry manure which was used in producing mushroom compost. Both workers were employed in the compost production area. Bo...

agaricus bisporus is the most important industrially cultivated edible mushroom. using organic wastes as substrate for cultivation of edible mushroom can provide a perfect solution for disposal of these waste materials and is part of the world's food requirements .in this study to investigate the usability of various organic wastes as growing bed for button mushroom, four types of substrat...

Actinobacteria are widely distributed in many environments and represent the most important trigger to the occupant respiratory health. Health complaints, including hypersensitivity pneumonitis of the workers, were recorded in a mushroom compost facility (MCF). The studies on the airborne bacteria were carried out to find a possible microbiological source of these symptoms. Culture analysis of ...

In order to evaluate the effect of medium and spraying calcium nano-fertilizer on quality of cut gerbera flowers, an experiment was conducted as factorial in completely randomized design with 7 media and 3 calcium nano-fertilizer concentrations with 3 replications. The media included cocopeat + perlite (1:1), peat moss + perlite (1:1), mushroom compost + perlite (1:1), peat moss + cocopeat + pe...

casing material or soil (casing) is used in mushroom (agaricus bisporus) culture to cover a nutritional composted substrate colonised with mycelium, and has an essential function in stimulating and promoting the development of sporophores (fruit bodies). in order to use the agricultural by products (different wastes) to reduce peat consumption of casing soil in button mushroom production, an ex...
