  • Ramanome / Meta-Ramanome

    2022-05-09

    Raman spectroscopy is a scattering technique that relies on the inelastic scattering of photons. The excitation of molecular bonds results in the shifts of the energy of laser photons and thus frequency change of the incident light. Therefore, a compound can have a specific Raman spectrum, while a Single-cell Raman Spectrum (SCRS) can depict the overall profile of metabolites in the cell, i.e.,...

    2022-12-23

    Researchers from the Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT) of the Chinese Academy of Sciences (CAS) have proposed a new technology, called optical tweezer-assisted pool-screening and single-cell isolation (OPSI) system, which achieves 99.7% purity of sorting target cells, with all done in real-time.The study waspublished in Lab on a Chip on Nov. 29.Versatile, facile ...

    The identification, sorting and export of single bacterial cells rather than just populations of them has long been incredibly complex, expensive and often just does not work without damaging the cells.Now, researchers from the Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT) of the Chinese Academy of Sciences (CAS) and their collaborators have proposed a new system called "Eas...

    Currently, the best way for scientists to isolate a specific microbe with a particular metabolic function from an environment is to take a sample of cells, culture them, and then screen them for the desired cell functions.This method has several limitations. First, scientists have not identified most cells in nature, limiting the results to previously cultured cells. Second, the way cells behav...

    ​Knowing whether or not marine microbes engage in photosynthesis — the use of sunlight to turn carbon dioxide and water into energy — could help scientist to learn if ocean bacteria play a role in the global carbon cycle.However, most marine microbes remain unstudied, in part because they do not grow under laboratory conditions, which limits the scientific community’s knowledge on if these ...

    2022-09-22

    The formation of persisters is an important feature of bacteria like Escherichia coli (E. coli). These noxious cells, being able to go dormant, are highly resistant to antimicrobial treatments and crucially account for various relapsing chronic infections with common symptoms such as severe stomach pain, vomiting and bloody diarrhea.Formation of persister cells is thought to be one of the most ...

    2022-09-07

    ​The genetic talents of a marine microalga are now unlocked, to produce medium-chain triacylglycerols, which is a kind of plant oil with a variety of health benefits, according to a study led by researchers from the Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT), Chinese Academy of Sciences (CAS).This study was published in Plant Physiology on August 30.A mechanistic model o...

    2022-06-20

    Helicobacter pylori (H. pylori), the bacteria that can cause human gastritis, peptic ulcers and stomach cancer, infects about half of the world's population. It is essential to quickly identify the infection and select the right combination of sensitive antibiotics. Current tools, however, are limited, mainly because H. pylori are slow growing and hard to cultivate.Researchers from the Qingdao ...

    Children are easily to become a vehicle for germs with less than perfect hygiene habits and a penchant for putting their hands and toys in their mouths.In a first-of-its-kind analysis of two kindergartens in China, researchers determined the proportion and species of microbes across a variety of surfaces and children’s palms. The most active sites, and likely routes of transmission, were the k...

    2022-04-19

    When treating acute infections in patients, health care providers must be able to quickly and accurately identify the best antibiotics for fighting the infection.A research team led by researchers from the Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT) of the Chinese Academy of Sciences (CAS) and Peking Union Medical College Hospital has developed an automated system that pro...
