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: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
