Researchers from Graz have examined which and how many bacteria are found in an Apple. The most found in the fruit flesh and the seeds, the peel, however, was less populated. What relates to the diversity and the positive effects of the species found, seem organic Apples to have the nose in front.
According to the results, we take an Apple about 114 million bacteria, unless he is completely eaten – Apples without core housing only contain about ten million bacteria. Professor Gabriele Berg, Graz University of technology explains: "The bacteria, fungi and viruses in our food settle temporarily in our intestines. Cooking kills most of them, which is why raw fruits and vegetables, microbes are a particularly important source for the Intestine."
Although the amount of bacteria on Apples from conventional and organic cultivation was the same, was the bacterial composition in different ways: organic Apples showed a more diverse and balanced bacterial community. Groups of bacteria, including known pathogens, were found in the majority of the Apples from conventional farming but not in organic Apples. The useful lactobacilli, it was different. Organic Apples could taste because of the bacteria even better: Methylobacterium, a type, known is that it promotes materials, the formation of strawberry aroma was of Apples in organic and in particular in the peel and in the flesh more common.
The results were published in the journal Frontiers in Microbiology, agree well with a recent study, the fungal communities in Apples were investigated: Both studies show that the Apple microbiome is the bacteria as well as fungi in fruits from organic farming is more diverse.
