In literature, the synergistic effect of several substrates on feedstocks for anaerobic digestion/methane production is described for several substrates. Champost from mushroom production, vermicompost from worm composting/vermiculture and BSF (black soldier fly) larvae frass from insect production were therefore tested for this report for their sy...
Until recently, food production focused mainly on delivering high-quality products at low cost and little attention was paid to environmental impact and depletion of natural resources. As a result of the growing awareness of climate change, shrinking resources, and increasing world population, this trend is changing. A major concern in Food Supply ...
The button mushroom, Agaricus bisporus var. bisporus, is one of the most cultivated mushrooms worldwide. Even though wild isolates of this variety have a broad genetic variation, the traditional and present-day hybrids only have a very narrow genetic base. The button mushroom has a typical meiotic recombination landscape (MRL) in which crossover (C...
During the last 35 years, hardly any breeding has been done in the button mushrooms (Agaricus bisporus). The fact that no new varieties are generated directed to trends in the food market has caused a slowly decrease in mushroom consumption in the Netherlands and in Europe. The hurdles for generating new varieties are difficulties in breeding and p...
The collection of Plant Breeding contains a large number of strains of Pleurotus eryngii and Lentinula edodes, two fungi producing edible mushrooms and also known by their selective degradation of lignin in lignocellulosic materials.
This thesis deals with the understanding of the water holding capacity of mushroom, in the context of a redesign of their industrial processing. For designing food process the retention of food quality is of the utmost importance. Water holding capacity is an important quality aspect of mushrooms. A convenient process design methodology which accou...
This report decribes experiments with anaerobic digestation of champost and organic rest products for re-use in mushroom casing. The digestates will reduce the emission of carbon dioxide by peat use for casing and will reduce the number of transport movements. Both reductions serve the mushroom sector. Wageningen UR Greenhouse Horticulture is measu...
Experiments described in this report were performed to increase the accuracy of the analysis of the biological efficiency of Agaricus bisporus strains. Biological efficiency is a measure of the efficiency with which the mushroom strains use dry matter in the compost to produce mushrooms (expressed as dry matter produced).
Abstract In this thesis, the fate of carbohydrates and lignin was studied in industrial wheat straw based compost during composting and growth of Agaricus bisporus. The aim was to understand the availability and degradability of carbohydrates in order to help improve their utilization in the compost. The wheat straw based compost was characterized ...
This report describes the results of a screening of genetically diverse strains of mushroom Agaricus bisporus for differences in taste. Eight different strains were grown on regular commercial compost and casing soil. Two of these strains were also grown on a casing with calcium chloride added to increase osmotic value. The intension was to increas...
