Gene expression in Bacillus subtilis surface biofilms with and without sporulation and the importance of yveR for biofilm maintenance.


Five independent DNA microarray experiments were used to study the gene expression profile of a 5-day Bacillus subtilis air-liquid interface biofilm relative to planktonic cells. Both wild-type B. subtilis and its sporulation mutant (DeltaspoIIGB::erm) were investigated to discern the important biofilm genes (in the presence and absence of sporulation). The… (More)
