A must import for Rest stops on highways and in service stations! Mainland scientists have developed a “bioweapon” that can wipe out the notorious bad smell in public toilets.
Up to 75 per cent of the odour can be removed, with the rest suppressed by a natural, pleasant fragrance, according to researchers with the Chinese Academy of Sciences.
The magic is mainly done by bacteria in the Lactobacillus family, which is used in the production of yogurt, cheese, beer and chocolate.
Lactobacillus feeds on human waste, releasing lactic acid that eliminates the growth of most odour-making bacteria.
The “smell-free toilet” study was highlighted on the academy’s website last month as offering an “ultimate” cure to an “urgent” national issue.
