New commercial varieties of oreille de chardon mushroom

07.05.2003


The Genetic and Microbiological research group at the Navarre Public University is working with the Agruset company from Rioja in the production of new commercial varieties of the fungus oreille de chardon mushroom (Pleurotus eryngii). The same group has developed 150 new varieties of the oyster mushroom (Pleurotus ostreatus), which enhances the productivity and quality of the varieties of this fungus which are currently being commercialised.



Mushroom agreeable to the palate

The Pleurotus eryngii mushroom, known in French as the oreille de chardon, is more agreeable to the palate and tastier than the Pleurotus ostreatus or the oyster mushroom, the variety which we most frequently find in the shops. The problem with the former is there is currently no standardised method for its cultivation or for the substrate in which it grows and, thus, its production is more expensive. A tray of P. ostreatus may cost 1.8€, whereas the eryngii will cost four times more.


A group of researchers from Navarre had a double objective. First, to standardise the growing conditions and substrate composition for the fungus and, secondly, to obtain new commercial varieties of this mushroom.

The standarisation phase for substrates is relatively short. The lengthiest process is the design of new varieties, because the most suitable strains in the available germoplasm have to be found, crossed amongst themselves and new molecular tools designed to enable directed crosses. It should be taken into account that these fungi are all the same in appearance, so some type of identification sign has to found.

I.D. card

Finally, the research includes typification and the drawing up of an identification card for the new varieties. One has to consider that the fungi propagate vegetatively, and so a company-improved piece there of may be picked and an identical sample achieved in its laboratory and, thus, all the investment carried out in research is in vain.

This card provides extra guarantees to companies like Agruset. It provides them with an ID card for its variety in such a way that it is assured, in the case of illegal commercial exploitation of the product, legal action can be undertaken.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
