FIG 6.

B. subtilis cells in chains prevent formation of the wrinkled coculture phenotype while single cells enhance it. (A) Colonies of B. subtilis lytABCDF (chained cells) cultured with increasing amounts of B. subtilis flgM (single cells) and spotted in monoculture (top) and in coculture with P. agglomerans (bottom) on MSgg and imaged after 48 h of growth. (B) B. subtilis flgM tasA double mutant grown in monoculture (top) and in coculture with P. agglomerans (bottom) on MSgg for 48 h. Bars, 1 mm.
