Dumpling dumplings have something to say:
Nagoya University in Japan has developed a technology that "the microorganisms can be easily broken by washing the microorganisms with a water pump, and specific microbial species".
Dumpling dumplings feel that this research topic is very interesting and shared with you~
The research was carried out by Professor Masahiro Masahiro of the Graduate School of Engineering, Nagoya University, and Associate Professor Anji Takashi, and Professor Yanagida of the Institute of Materials Chemistry of Kyushu University and Professor Kawasaki Chiji of the Institute of Industrial Science of Osaka University.
The research results are published on the website of the American Chemical Society magazine《ACS Nano》. If your profession is related to medicine, if you are interested, it is recommended to search for it~
The first line is from left to right: introduction of microbial suspension, microbial disruption, and DNA extraction. The second line is from left to right: adsorption, entanglement, cell deformation, breakage
Microorganisms have cell walls, so they are more resistant to external stimuli than animal cells. In general, the type of microorganism can be determined by investigating the DNA inside the microorganism.
In the past, because there was no technology to efficiently and easily break down microorganisms, specific microorganisms were prepared by experts with special agents. In other words, it is just a matter of how to efficiently and easily break down microorganisms and investigate the DNA inside the microorganisms.
This time, the research team led by Professor Ma Xing Jiaxin re-developed the microbial disruption method that activates the characteristics of nanorods (nanowires): the microorganisms are efficiently and easily pulverized by flushing the solution in which the microorganisms are dispersed by a water pump. It can be said that it is a subversive innovation in the past microbial disruption technology!
The most amazing thing is that this technology can also easily handle yeast that is harder to break than coliforms and subtilis!
