As a follow up experiment for the last [https://2010.igem.org/Team:Groningen/23_August_2010 biofilm induction ] ''Bacillus subtilis'' wit Chaplin E and chaplin H were grown while continuously adding subtilin to keep expression up. After 3hrs of growth they where induced with 1%subtilin. Every hour an additional 0.5%subtilin was added. As a negative control uninduced strains where used. Furthermore shaking cultures (induced and uninduced) where grown simultaneously to check OD levels. Only the chaplin E strain showed reduced growth, but no differences other than retarded growth were visible. | As a follow up experiment for the last [https://2010.igem.org/Team:Groningen/23_August_2010 biofilm induction ] ''Bacillus subtilis'' wit Chaplin E and chaplin H were grown while continuously adding subtilin to keep expression up.

Expression experiments -David & Peter
Two expression experiments were done this week.
Continous induction of chaplins
As a follow up experiment for the last biofilm induction Bacillus subtilis wit Chaplin E and chaplin H were grown while continuously adding subtilin to keep expression up. After 3hrs of growth they where induced with 1%subtilin. Every hour an additional 0.5%subtilin was added. As a negative control uninduced strains where used. Furthermore shaking cultures (induced and uninduced) where grown simultaneously to check OD levels. Only the chaplin E strain showed reduced growth, but no differences other than retarded growth were visible.
