Determination of No and Csf Levels Produced by Bacillus Subtilis
Bio-protocol(2017)
摘要
The cell-to-cell communication and division of labour that occurs inside a beneficial biofilm produce significant differences in gene expression compared with the gene expression pattern of cells grew under planktonic conditions. In this sense, the levels of NO (nitric oxide) and CSF (Competence Sporulation Stimulating Factor) produced in Bacillus subtilis cultures have been measured only under planktonic growth conditions. We sought to determine whether NO and/or CSF production is affected in B. subtilis cells that develop as a biofilm. To measure the production levels of the two prolongevity molecules, we grew B. subtilis cells under planktonic and biofilm supporting condition.
