    Observing Nutrient Gradients, Gene Expression and Growth Variation Using the "Yeast Machine" Microfluidic Device
    [Abstract] The natural environment of microbial cells like bacteria and yeast is often a complex community in which growth and internal organization reflect morphogenetic processes and interactions that are dependent on spatial position and time. While most of research is performed in simple homogeneous environments (e.g., bulk liquid cultures), ...
    Assembly of a Custom-made Device to Study Spreading Patterns of Pseudomonas putida Biofilms
    Authors:  David R. Espeso, Esteban Martínez-García and Víctor de Lorenzo, date: 05/20/2019, view: 2221, Q&A: 0
    [Abstract] Biofilms are bacterial communities in the shape of exopolysaccharide matrix-encased aggregates attached onto interphases able to resist environmental aggressions. The development of bacteria in the shape of biofilms deeply affects the performance of many industrial processes which work with fluidic systems, where bacteria may settle and prosper. ...
    Microfluidics-Based Analysis of Contact-dependent Bacterial Interactions
    Authors:  Robert Cooper, Lev Tsimring and Jeff Hasty, date: 08/20/2018, view: 3343, Q&A: 0
    [Abstract] Bacteria in nature live in complex communities with multiple cell types and spatially-dependent interactions. Studying cells in well-mixed environments such as shaking culture tubes or flasks cannot capture these spatial dynamics, but cells growing in full-fledged biofilms are difficult to observe in real time. We present here a protocol for ...
