Kitchen sponges can trap dirt, why do you know?

The study suggests that ordinary kitchen sponges may be better suited to cultivating bacterial communities than biology lab dishes because the structure of sponges affects interactions between microbial species,cellulose sponge sheet which helps bacteria multiply.

According to a new study, it's not just the food scraps left behind,konjac body sponge 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, bacterial communities are mixed to varying degrees,steel sponge and the soil provides space for different populations to grow, allowing them to live more independently without having to interact as much with their neighbors. However, if humans culture bacterial species to produce products such as alcohol, biofuels, and drugs, we simply place them on plates or vats in LABS or factories to make shapeless sticky substances, such an environment often leads to frequent "ballroom dances" between bacteria.

Different species of bacteria, each designed to emit a different color, helped the researchers track their growth.

"Bacteria are like people who have experienced epidemics," said Dr. You, a professor in the School of Biomedical Information Engineering at Duke University. "Some people are slow to recover, while others are resilient." "We in China have demonstrated that in a complex bacterial community with both active and some negative interactions in the country, the presence of such a state of fusion working at a secondary level of education will maximize the overall coexistence of all bacteria." By setting up a series of experiments, the scientists showed that different microbial species can directly affect their populations of each other, depending on the environmental risk factors they live in, such as the size of their living 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.

"Small amounts of nutrients inhibit bacteria that depend on interactions to survive, while excess nutrients inhibit bacteria that grow independently," explains Dr. You. "But the moderate amount of nutrients was just right to maximize the diversity of survivors in the microbiome." This explains why kitchen sponges are the best habitat for microbes, mimicking the state of healthy soil, providing both isolated Spaces and Spaces for coexistence of different sizes, making the place a favorite for 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."

Bacteria move in ordinary household sponges

These data results provide scientists who study different bacterial communities with a systematic framework to test which structural environment is most suitable for their research, which must be fully taken into account in the management of our use of bacteria in the production development process.
