A UGR group studies the uses of "alpechín" (seepage from olives pressings) in the drug and food industries

20.10.2006
The Paenibacillus jamilae bacterium is a microorganism capable of developing in "alpeorujo", and was described as a new species in the year 2001.

The interest of the research of the group directed by Alberto Ramos Cormenzana is due, to a great extent, to "jamilano", a substance produced by this bacterium. At the moment, according to Professor Ramos Cormenzana, “we are in conversations with the DOMCA Company, from Granada, to use it in the food sector”. In this sense, it could be used for giving consistence and texture to products like creme caramels or cremes.

Margarita Aguilera´s contribution is important for achieving these objectives and others which would place "jamilano" as an essential constituent in soil decontamination and fertilization. This scientist, belonging to the "Halophilic microorganisms" research group directed by Ramos, has practically managed to clone the gene of this microorganism.

The research originated from the study of the disinfection of waters contaminated with "alpechín" started in the late seventies. Fron that moment, the UGR [http://www.ugr.es] Profesor and his team have collaborated with companies from Madrid and Jaén, together with other Italian research groups of the public and private sectors in the observation of how the composting of "alpechín" could be used to cultivate tomatos and mushrooms.

On the other hand, its uses in the field of pharmacy are being studied. Laboratory studies in-vitro and in animals are being carried out to test its toxicity level and the modulation of the biological response of a living organism. “The idea is to test if this compound could be used together with the medicine in question with a specific action or vaccine production”, Ramos Cormenzana explains.

Two-phase system

The research group belongs to a European network on olive oil production systems and remains use. In Spain, the production process has been changed by using the two-phase system which mixes "alpechín" and "orujo" to reduce the resulting "alpechín" volume. Extractors are suffering now from the ecological problem of waste and have started to look for uses of this new product, "alpeorujo".

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Im Focus: Cold molecules on collision course

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Im Focus: Shrinking the proton again!

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
