BASF discovered a new strain of lactobacillus called L. anti-caries, which binds to Strepptococcus mutans, the bacteria responsible for tooth decay. S. Mutans sticks to the surface of teeth, where it produces an aggressive acid that breaks down the enamel. The friendly bugs in the gum will make the S. Mutans clump together, preventing them from becoming attached to the tooth surface. Tests reveal that the chewing gum can reduce the amount of bacteria in the mouth fifty times.
Stefan Marcinowski, executive director of research at BASF said that a Lactobacillus product is due to hit the supermarkets in 2007, but would not confirm whether it is the chewing gum. Marcinowski says that the chewing gum ‘has been tested on large numbers of people and demonstrated the ability to significantly reduce bacterial levels.’ A new range of toothpastes and mouthwashes using L. anti-caries are also in the pipeline.
Chewing gums containing the artificial sweetener xylitol, which has antimicrobial properties, have also been shown to suppress the bacteria that fight tooth decay.
Other potential uses of Lactobacillus include the prevention of body odour. BASF are looking into producing a deodorant based on L. aladoris, which can inhibit odour-producing bacteria in the armpit. Similarly, tests have shown another strain, L. ala-odoris can reduce odour formation in feet.

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.
The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...
