Is it really clean to brush the bowl with sponge?

The study proved that the average kitchen sponge may be better for cultivating bacterial communities than the petri dish in a biology lab,cellulose sponge sheet because the structure of the sponge affects the interactions between microbial species, favoring the rampant growth of bacteria.

According to a new study,konjac body sponge it's not just the food scraps left behind, but the structure of the sponges themselves that allows microbes to thrive in them. In fact, some bacteria prefer to live in diverse communities, while others prefer to coexist only with bacteria that are similar to themselves, so an environment that allows both bacteria to live the best lives leads to the strongest bacterial diversity. In a natural setting, soil provides the best mixed living environment, and so does your kitchen sponge. The results, published in the journal Nature Chemical Biology, could not only help you clean your kitchen, but also provide a reference for various industries that use bacteria to produce food, medicine, energy and other products.

In nature, the bacterial community structure is mixed with different levels of culture,steel sponge and the soil provides the space needed for different populations to grow and develop, allowing them to live more independently without having to interact with their neighbors too much. But when human societies cultivate bacterial species to produce corporate products, such as alcohol, biomass for fuel, and medicine, we ourselves in laboratories or factories simply place them primarily on a plate or in a VAT to form a shapeless goo, such environmental problems often involve "ballroom dancing" between bacterial systems.

Different types of bacteria, each of which emits a different color, help researchers track their growth.

Dr. You, a professor of biomedical engineering at Duke University in the United States, said: "Bacteria are like people experiencing an epidemic. Some people are slow to recover, others are full of vitality. "We have shown that in a complex bacterial community with both positive and negative interactions, there is a moderate degree of integration that maximizes the overall coexistence of all bacteria. "Through a series of experiments, the scientists demonstrated that different microbial species can influence each other's populations depending on the environmental factors they live in, such as the size of the environment.

They encoded the genomes of about 80 different strains of E. coli to track their population growth, and then mixed the bacteria in different combinations in petri dishes in the lab. The petri dishes provided a wide variety of potential habitats for bacteria - from six large colonies to 1,536 small colonies.

These communities can be designed to mimic the different environments in which bacteria might like to grow. A large community is similar to an environment where many microbial species can mix freely, and a small community is similar to an independent space where bacteria can remain independent. Interestingly, the end result was the same regardless of the size of the habitat: the bacteria evolved into a community with only one or two surviving strains, but the mesobacterial community had the greatest diversity.

"The small amount of nutrition inhibited the bacteria that depended on the interaction of enterprises to survive, while the excess inhibited the bacteria that the students could grow independently," Dr. You explained. "But the middle portion is just enough to maximize the diversity of survivors in our microbiome." This may explain why kitchen sponges are the best habitat for microbes, which have been studied to provide a cavity that is isolated from each other and can also provide a variety of different sizes of coexistence, mimicking the health effects in the soil, such places are simply the favorite of bacteria.

To prove this, the researchers also tested a common household sponge and found that it was better at cultivating microbial diversity than anything the lab had previously used. Dr Yau said: "It turns out that sponges are a very simple way to achieve multi-level distribution of nutrients and improve the entire microbial community. Maybe that's why it's so dirty - the sponge's structure is exactly the perfect home for microbes."

The results provide a framework for scientists studying different bacterial communities to test which structural environments are best suited for their research, and which companies using bacteria in their production must take into account.
