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

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: Novel light sources made of 2D materials

Physicists from the University of Würzburg have designed a light source that emits photon pairs. Two-photon sources are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape.

So-called monolayers are at the heart of the research activities. These "super materials" (as the prestigious science magazine "Nature" puts it) have been...

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Terahertz excitation of selected crystal vibrations leads to an effective magnetic field that drives coherent spin motion

Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how...

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
