“…bisporus As A. bisporus does not fruit in axenic culture, studies were undertaken using stage 1 (pin) sporophores as defined by Hammond & Nichols (1976). In stage 1 sporophores, metabolic effects owing to fiushing are not obscured by those arising from growth and maturation of sporophores which occur at later stages.…”

“…occurs periodically in a series of flushes approximately at weekly intervals; very few fruit bodies are produced between flushes. Hammond & Nichols (1976) first observed that, during fruit-body growth, concentrations of trehalose (percentage dry weight) declined in both sporophore and mycelium. Concentrations of protein in the sporophore also declined with growth.…”

VARIATIONS IN ACTIVITIES OF GLYCOGEN PHOSPHORYLASE AND TREHALASE DURING THE PERIODIC FRUITING OF THE EDIBLE MUSHROOM AGARICUS BISPORUS (LANGE) IMBACH.

SUMMARYActivities of trehalase and glycogen phosphorylase were determined for stage 1 (pin) sporophores of Agaricus bisporus harvested daily throughout several fruiting cycles (flushes). Both enzymes exhibited maximum activity coincident with peak flush, as defined by maximum yield of stage 2 to 4 sporopbores and minimum activity during the interflush periods. Glycogen phosphorylase activity sometimes peaked on more than one occasion during a flush, whereas trehalase gave only a single peak of activity per flush. These results are discussed in relation to metabolic events associated with carbobydrate changes during tbe periodic fruiting cycle of tbis fungus.

“…As a result, it may increase the content of mannitol in natural C. sinensis (Wang et al 2009; Guan et al 2010). Increased mannitol is related to fruiting body initiation and development of A. bisporus (Kulkarni, 1990), and the mannitol content in the fruiting body of A. bisporus is about 8–20 times higher than that in mycelia (Hammond and Nichols 1976; Wannet et al 2000). …”

Potential molecular mechanisms for fruiting body formation of Cordyceps illustrated in the case ofCordyceps sinensis

et al. 2017

The fruiting body formation mechanisms of Cordyceps sinensis are still unclear. To explore the mechanisms, proteins potentially related to the fruiting body formation, proteins from fruiting bodies, and mycelia of Cordyceps species were assessed by using two-dimensional fluorescence difference gel electrophoresis, and the differential expression proteins were identified by matrix-assisted laser desorption/ionisation tandem time of flight mass spectrometry. The results showed that 198 differential expression proteins (252 protein spots) were identified during the fruiting body formation of Cordyceps species, and 24 of them involved in fruiting body development in both C. sinensis and other microorganisms. Especially, enolase and malate dehydrogenase were first found to play an important role in fruiting body development in macro-fungus. The results implied that cAMP signal pathway involved in fruiting body development of C. sinensis, meanwhile glycometabolism, protein metabolism, energy metabolism, and cell reconstruction were more active during fruiting body development. It has become evident that fruiting body formation of C. sinensis is a highly complex differentiation process and requires precise integration of a number of fundamental biological processes. Although the fruiting body formation mechanisms for all these activities remain to be further elucidated, the possible mechanism provides insights into the culture of C. sinensis.

The agronomic performance of different proportions of mixtures of coconut fibre (CF) pith and spent mushroom substrate (SMS) was studied for their use as casing material in mushroom cultivation. After chemical and biological characterisation of the casing substrates qualitative and quantitative production parameters were evaluated in a cycle of Agaricus production. An increase in the proportion of SMS reduced the number of carpophores and overall yield; while the first flush was delayed, mushroom size tended to increase and the mushrooms had a higher dry matter content and a better texture, although their colour was worse. Combinations of CF pith and SMS of 4:1 and 3:2 (v/v) gave biological efficiencies of 92.9 and 82.6 kg 100 kg -1 compost, respectively. These values compare well with that obtained from the commercial casings used as a control. The high electrical conductivity of the mixture containing the highest proportion of SMS would limit its use. However, the results indicate the viability of reusing SMS as an ingredient of casing material for mushroom cultivation. This alternative could be considered to partially replace the organic substrates normally used for mushroom cultivation, with the double advantage of decreasing cost and reducing the environmental impact of waste disposal.Additional key words: alternative casing, compost reuse, mushroom cultivation. ResumenEvaluación de sustratos de cobertura basados en compost agotado y fibra de coco en la producción de Agaricus bisporus (Lange) Imbach.Se describe en el presente trabajo el estudio del comportamiento agronómico proporcionado en cultivo de champiñón por sustratos de cobertura basados en mezclas de fibra de coco (CF) y compost agotado (SMS) en diferentes proporciones. Para ello, tras la caracterización física, química y biológica de los sustratos de cobertura, se evaluaron los parámetros de producción cualitativos y cuantitativos en un ciclo de cultivo de Agaricus bisporus. Se observó que al aumentar la proporción de SMS en las mezclas disminuyó el número de carpóforos cosechados y el rendimiento total, a la vez que se vio retrasada la cosecha de la primera florada, aunque tiende a aumentar el tamaño de los champiñones cosechados, que presentan mayor contenido en materia seca, mejor textura y peor coloración. Combinaciones de CF y SMS 4:1 y 3:2 (v/v) proporcionaron, respectivamente, eficiencias biológicas de 92,9 y 82,6 kg/100 kg compost, comparables a las proporcionadas por las coberturas empleadas como testigo. Aunque la elevada conductividad eléctrica de las mezclas con alta proporción de SMS suponen una limitación a su empleo, los resultados obtenidos muestran la viabilidad de la reintroducción del SMS de champiñón en nuevos ciclos de cultivo empleándolo como ingrediente de mezclas de cobertura. Esta aplicación constituye una alternativa a considerar en la producción comercial para reemplazar parcialmente a los sustratos orgánicos empleados habitualmente para este fin, con la doble ventaja de disminuir los costes de elaboración y el i...
