University of Leicester scientists discover technique to help 'friendly bacteria'

... qualities of friendly bacteria such as the lactic acid bacteria, which are found in most ... generated in such a short space of time. Although lactic acid bacteria play a major role in the production ... the main values of LabEnhancer is that it helps lactic acid bacteria to recover from these stresses ...

Joint research into an enzyme that causes genetic diseases

... is not adequately performed (for example, when mutations in the gene arise) diverse metabolic diseases of genetic origin are triggered, amongst them lactic acidaemia, hypoglycaemia, and psycho-motor retardation. At the same time, being at a metabolic crossroads, pyruvate carboxylase is potentially a ...

Natural-born divers and the molecular traces of evolution

... increase of the amino acid histidine in the myoglobin of strong divers, which may allow the animal to deal better with the accumulation of lactic acid that is frequent during long dives (the same build up is the cause of the cramps we sometimes get during strenuous exercise). In order to ...

Guilt on their hands: tiny 'tags' could help to solve and deter gun crime

... when heat is rapidly transferred from the burning propellant into the cartridge case and (ii) when copper is extracted from the cartridge case by lactic acid in sweat. The nanotag and DNA capture technologies could potentially be available for use within as little as 12 months. There may also be ...

U of Minnesota researchers discover key for converting waste to electricity

... The bacteria, Shewanella, are commonly found in water and soil and are of interest because they can convert simple organic compounds (such as lactic acid) into electricity, according to Daniel Bond and Jeffrey Gralnick, of the University of Minnesotas BioTechnology Institute and department of ...

Want healthy gums? Hit the dairy aisle

... depth (PD) and clinical attachment loss (CAL) of gum tissue. Researchers observed that subjects that consumed 55 or more grams of products containing lactic acid each day had a significantly lower prevalence of deep PD and severe CAL, therefore demonstrating a lower instance of periodontal disease. ...

Using green chemistry to deliver cutting-edge drugs

... prolonging the length of time over which active therapeutic is released at the delivery site. The polymer used is a biodegradable plastic based on lactic acid, which is a natural compound produced in the body that the body is able to get rid of in the usual way. It is used in dissolvable stitches and ...

Genomic comparison of lactic acid bacteria published

... food supply of such benign microbial players as lactic acid-producing bacteria. Researchers from the ... the genome sequences of nine different lactic acid-producing bacteria, or LAB, and have ... promising broad industrial applications. lactic acid-producing bacteria play a key role in the ...

Lactic acid not athlete's poison, but an energy source - if you know how to use it

... In the lore of marathoners and extreme athletes, lactic acid is poison, a waste product that builds up in ... Berkeley, however, tells a different story: lactic acid can be your friend. Coaches and athletes ... training teaches the body to efficiently use lactic acid as a source of fuel on par with the ...

Xylitol reduces risk of cavities

... of the bacteria, but this did not lead to a lower production of lactic acid in plaque. In another study it was shown that a single higher intake ... dose of 6.0 grams of xylitol. The amount of plaque and the production of lactic acid declined dramatically during the trial period. After four weeks, the ...

Hopkins researchers discover genetic switch that turns off an oxygen-poor cell's combustion engine

... School of Medicine. Dang says the switch may be a target for cancer drugs because a cancer cell's survival depends on it to convert glucose to lactic acid through glycolysis even in the presence of ample oxygen. Disruption of the switch by a drug may cause cancer cells to pollute themselves with ...

Bacteria that cause tooth decay able to survive without important biochemical pathway

... its natural environment, it is typically S. mutans that goes on the attack. When sugary foods are eaten, the S. mutans population explodes, excreting lactic acid as it digests sugar. The acid makes life difficult for other helpful bacteria and demineralizes tooth enamel, causing decay. According to the ...

Development of portable infectious disease detector

... of a sensor suite capable of simultaneously measuring the concentrations of the key chemicals that cells consume and excrete--oxygen, glucose and lactic acid--with enough sensitivity to monitor the health of a few thousand cells confined in a small volume. (For more detail see "New device can help ...
