    Authors:  Thurston Herricks, Magdalena Donczew, David R. Sherman and John D. Aitchison, date: 05/20/2021, view: 559, Q&A: 0

    Antimicrobial-resistant Mycobacterium tuberculosis (Mtb) causes over 200,000 deaths globally each year. Current assays of antimicrobial resistance require knowledge of the mutations that confer drug resistance or long periods of culture time to test growth under drug pressure. We present ODELAM (One-cell Doubling Evaluation of Living Arrays of

    High-throughput Method for Detecting Siderophore Production by Rhizosphere Bacteria
    Authors:  ShaoHua Gu, Wen Wan, ZhengYing Shao and Wei Zhong, date: 05/05/2021, view: 527, Q&A: 0

    Siderophores, a key substance that microorganisms produce to obtain iron under iron-limited conditions, play an important role in regulating interactions between beneficial bacteria and pathogenic bacteria. A large number of bacteria were isolated from the rhizosphere, and we used the method presented here to assay the siderophore production by

    COVID-19 Sample Pooling: From RNA Extraction to Quantitative Real-time RT-PCR

    The COVID-19 pandemic requires mass screening to identify those infected for isolation and quarantine. Individually screening large populations for the novel pathogen, Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), is costly and requires a lot of resources. Sample pooling methods improve the efficiency of mass screening and consume

    Simple Time-lapse Imaging for Quantifying the Hydrostatic Production of Oxygenic Photogranules
    Authors:  Esmee D. Joosten, Jérôme Hamelin and Kim Milferstedt, date: 10/05/2020, view: 1083, Q&A: 0
    [Abstract] Oxygenic photogranules (OPGs) are dense, three-dimensional aggregates containing a syntrophic, light-driven microbial community. Their temporal and spatial development interests microbial ecologists working at the bioprocess engineering interface, as this knowledge can be used to optimize biotechnological applications, such as wastewater treatment ...
