Sucrose/Levan's glue

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

Hyperspankoid characterisation

Aims

The aim of these experiments is to ligate the promoters hyperspankoid, pspacoid and hyperspank in front of RFP of the pSB1C3 plasmid. In order to do this, the first step is to amplify the three promoter sequences and the pSB1C3 plasmid using Phusion PCR and the different primers and template DNA.

Materials and Protocol

Please refer to Phusion PCR for Phusion PCR protocol.

The details of the four PCR reactions are included in the table below:

Tube Part to be amplified DNA fragment consisting the part i.e. template Forward primer Reverse Primer Melting Temperature (Tm in °C) Size of the fragment (in bp) Extension time (in seconds)
1 Hyperspankoid yneA Prom_for HpSpanPspacoid_rev 65 15
2 Pspacoid kinA Prom_for HpSpanPspacoid_rev 65 15
3 Hyperspank K143055 from Bacillus plate - BS022 Prom_for Pspac-hy rev 62 15
4 Plasmid vector pSB1C3/RFP Vector/RFP_for P2-V1 64 60

Table 1: The table shows the four different Phusion PCR reactions carried out for the characterisation of the hyperspankoid promoter.
