Is it really clean to brush the bowl with coconut silk?

This study demonstrates that a common kitchen coconut sponge may be better at culturing bacterial communities than a bio-lab dish because the structure of the coconut sponge influences interactions between microbial species, kitchen scrubber manufacturerconducive to rampant growth of bacteria.

According to a new study, not only the food scraps left behind, but also the structure of the coconut sponge itself allows microorganisms to thrive in it. In fact, some bacteria prefer to live in diverse communities, while others prefer to coexist only with bacteria similar to themselves, so an environment that allows both bacteria to live the best life will lead to the strongest bacterial diversity. In the natural environment, soil provides the best mixed living environment, so does your kitchen coconut sponge. The research results published in Nature Chemical Biology can not only help you clean the kitchen, but also provide reference for various industries that use bacteria to produce food, medicine, energy and other products.

In nature, bacterial community structures are mixed with different levels of culture, and the soil provides space for different populations to grow and develop, allowing them to live more independently, without too much interaction with the neighbors. But when human societies cultivate bacterial species to produce corporate products such as alcohol, biofuels and pharmaceuticals, our own environmental problems in laboratories or factories simply place them primarily on plates or VAT to form an invisible sticky substance, which often involves“Social dances” between bacterial systems.

Different types of bacteria, each emitting different colors, help researchers track their growth.

Dr. Yu is a professor of biomedical engineering at Duke University, “Bacteria are like people going through an epidemic,” he said. Some people recover slowly, others are full of energy. “We have shown that in a complex bacterial community with both positive and negative interactions, there is a modest degree of integration that maximizes the overall coexistence of all bacteria. “In a series of experiments, scientists have shown that different microbial species can influence each other's population size based on environmental factors such as the size of the environment in which they live.

They encoded the genomes of about 80 different strains of E.coli to track their population growth, and then mixed these bacteria in different combinations in a Petri dish in the laboratory. Petri dishes provide a variety of potential habitats for bacteria-from 6 large colonies to 1536 small colonies.

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

"A small amount of nutrition inhibits bacteria that depend on enterprise interaction, while an excessive amount inhibits bacteria that students can grow independently," Dr. You explained. "But the middle part is enough to maximize the diversity of survivors in our microbial community." This may explain why kitchen coconut sponges are the best habitat for microorganisms. They have been studied to provide an isolated cavity, and they can also provide coexistence of different sizes to imitate the health effects in the soil. Such places are simply the favorite of bacteria.

To prove it, the researchers also tested a common household coconut sponge and found it was better at cultivating microbial diversity than anything previously used in the lab. “It turns out that coconut sponges are a very simple way to achieve multi-layered distribution of nutrients and improve the overall microbial community,” Dr. Chiu said. Maybe that's why it's so dirty-the structure of a coconut sponge is a perfect home for microbes.”

Bacteria move in ordinary household coconut sponge.

The results provide a framework for scientists studying different bacterial communities to test which structural environments are most suitable for their research and which companies that use bacteria in their production must take into account.
