英文摘要 | Quorum sensing (qs) is a process that enables bacteria to communicate using secreted signaling molecules, and then makes a population of bacteria to regulate gene expression collectively and control behavior on a community-wide scale. theoretical studies of efficiency sensing have suggested that both mass-transfer performance in the local environment and the spatial distribution of cells are key factors affecting qs. here, an experimental model based on hydrogel microcapsules with a three-dimensional structure was established to investigate the influence of the spatial distribution of cells on bacterial qs. vibrio harveyi cells formed different spatial distributions in the microcapsules, i.e., they formed cell aggregates with different structures and sizes. the cell aggregates displayed stronger qs than did unaggregated cells even when equal numbers of cells were present. large aggregates (la) of cells, with a size of approximately 25 mu m, restricted many more autoinducers (ais) than did small aggregates (sa), with a size of approximately 10 mu m, thus demonstrating that aggregate size significantly affects qs. these findings provide a powerful demonstration of the fact that the spatial distribution of cells plays a crucial role in bacterial qs. |
