The coconut sponges in the kitchen suck up dirt. How do you know?

This study shows that the ordinary kitchen coconut sponge may be more suitable for cultivating bacterial communities than the plates in the biological laboratory,kitchen scrubber manufacturer because the structure of coconut sponge will affect the interaction between microbial species, which is helpful for bacterial reproduction.

Not just the food residue, but the structure of the coconut sponge itself allows microbes to thrive in it, according to a new study. In fact, some bacteria like to live in different communities, while others like to live only with bacteria that are similar to themselves, so, an environment in which both bacteria can live the best life results in the strongest bacterial diversity. In a natural setting, soil provides the best mix of living conditions, as does your kitchen coconut sponge. The findings, published in the journal Nature Chemical Biology, could not only help you clean your kitchen, but also inform a variety of industries that use bacteria to produce food, medicine, energy and other products.

In nature, bacterial communities are mixed to varying degrees, 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 types of bacteria give off different colors, helping researchers track their growth.

Dr. You, a professor at Duke University's School of Biomedical Information Engineering, said: "Bacteria are like people who have experienced epidemics. "Some people recover slowly, while others are resilient. ""We have proved in China that in a complex bacterial community, there are both positive and negative interactions, and the existence of this fusion state at the secondary education level will maximize the overall coexistence of all bacteria. " By setting up a series of experiments, scientists show that different microbial species can directly affect each other's populations, depending on the environmental risk factors in which they live, such as the size of their living environment.

They coded the genomes of about 80 different strains to track their population growth, and then mixed the bacteria in different combinations in laboratory dishes. The Petri dishes provide a wide variety of potential habitats for bacteria -- from six large colonies to 1,536 small colonies.

These communities can be designed to simulate different environments in which bacteria may like to grow. A large community is similar to an environment where many microbial species can mix freely, while a small community is similar to a bacterium that can maintain an independent space. Interestingly, regardless of the size of the habitat, the final result is the same: bacteria have evolved into a community with only one or two surviving strains, but the medium-sized bacterial community has the greatest diversity.

“A small amount of nutrients inhibits bacteria that rely on interactions to survive, while an excess of nutrients inhibits bacteria that grow independently,” you explained. “But just the right amount of nutrition can maximise the diversity of survivors in the microbial community. “This explains why the coconut sponge in the kitchen is the perfect habitat for microbes, mimicking the state of healthy soil, providing separate spaces and spaces for microbes of different sizes to coexist, making it a favorite place for 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.”

These data results provide a systematic framework for scientists studying different bacterial communities to test which structural environment is most suitable for their research, which must be fully considered in the management of using bacteria in the production and development process.
