| Abstract: | Cells of the myxobacterium Stigmatella aurantiaca increased in cohesiveness during the aggregation stage of fruiting body formation. Cell cohesion was genus specific, as determined by suspending S. aurantiaca cells with other bacteria and measuring their inclusion in the cell clumps. Cohesion between aggregating cells became resistant to moderate shear stresses (vortex mixing) approximately at the aggregate stage. Cells harvested prior to the appearance of aggregates formed shear sensitive followed by shear resistant cohesions in cell suspension. |
