-
We started working on the Levans glue. For this we used agar plate containing 10% sucrose and ''Bacillus sphaericus'' strain was grown onto that medium. The sucrose cultures and controls were compared. The cultures grown on sucrose should be considerably thicker.

Today we checked for transformants from the filamentous ''Bacillus subtilis'' transformation (with pMutin4) we performed yesterday.

The overnight cultures of the different strains were also grown on solid agar plates with and without sucrose.

===Aims===
+
-
The aim of these experiments is to ligate the promoters hyperspankoid, pspacoid and hyperspank in front of ''rfp'' on  the pSB1C3 plasmid seperately. In order to do this, the first step is to amplify the three promoter sequences and the pSB1C3 plasmid using Phusion PCR.

Checking for transformants

Today we checked for transformants from the filamentous Bacillus subtilis transformation (with pMutin4) we performed yesterday.

We checked our transformants under the light microscope, expecting to see a non-filamentous phenotype since the cells had not been induced with IPTG. The resutls were as expected.
