Is a sponge really clean?

This study proves that ordinary kitchen sponge may be more suitable for cultivating bacterial communities than Petri dishes in biological laboratories, stainless steel spongebecause the structure of sponge will affect the interaction between microbial species and is conducive to the rampant growth of bacteria.

According to a new study, 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, 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.

Each type of bacteria gives off a different color, which helps researchers track their growth.

Magic sponge is an easy to use cleaning tool. When dealing with some bad stains or stains that can't be treated with a rag, it is especially necessary to show her strong cleaning ability, because basically only water is needed to remove stubborn stains, so that the cleaned things can achieve the effect of exchanging old ones for new ones. You may ask, how is this done? Don't worry, here is a little makeup for you to answer.

First, we have to start with the materials and structure of the magic sponge. The “Magic sponge” is made of melamine foam developed and manufactured by the National Nanomaterials Technology and Information Industry Corporation, with an open-cell 3D network inside. Through the analysis of this economic and social organizational structure, students can make the magic sponge immersed in water, and in the process of wiping automatic control of the study object important surface stains adsorption. The magic sponge wipe is a pure physical purification that is safe and environmentally friendly.

Suitable for cleaning uneven surfaces and deep stubborn dirt, easy to maintain, no scratches, no damage to the surface of objects, convenient to use, no need for chemical cleaning agents. Because of the internal open structure of the magic sponge, the adsorbed stains can be discharged after being pressed in water, and then can be reused, which is very convenient.

Because this magic sponge is expendable, it wears off when you use it. So to properly control moisture, too dry is more likely to lead to peeling to eat.
