Most bacteria from craft goat’s cheese come from lactic acid and could be very beneficial for health

29.01.2009
A research work carried out at the Department of Microbiology of the University of Granada has carried out an analysis of the DNA extracted from different varieties of craft goat’s cheese, determining that most of them belong to the group of lactic bacteria, which could have important technological and functional properties, and be even beneficial for health.

The doctoral thesis by Antonio M. Martín Platero has been supervised by Professors Manuel Martínez Bueno, Mercedes Maqueda and Eva Valdivia, and is the first research work carried out around Andalusian cheese through the combination of classic and molecular techniques and/or methodologies.

In order to carry out this work, they have analysed four varieties of craft cheese from the Alpujarra (Granada), Jayena (Granada) and Aracena (Huelva). The microbiological analysis carried out at the University of Granada has revealed that this cheese possess between 107 and 109 bacteria per gram of cheese, and between 65 and 99 per cent of them are LAB (Lactic Acid Bacteria).

Lactic acid, beneficial for health

Martín Platero highlights that this type of bacteria “could be especially beneficial for human health, as they cause fermentation in lactose, acidify the PH and therefore prevent development of pathogen microorganisms”. Part of the microorganisms produce numerous antimicrobial compounds of protein nature known as bacteriocines, very active substances against pathogens and other microorganisms which alter food.

According to the study carried out at the UGR, the most abundant species found in such craft cheese are Lactobacillus paracasei, Lb. plantarum and Lactococcus lactis. The latter is one of the species most commonly found in yoghurt.

The results of this work have been partially published in the scientific journals Applied and Enviromental Microbiology, International Journal of Food Microbiology y Analytical Biochemistry.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
