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: Electron highway inside crystal

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.

Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
