Problem

Genomic DNA extraction from Bacillus subtilis strain ATCC 6633

Aim

The aim of this experiment was to extract genomic DNA from Bacillus subtilis strain ATCC 6633. This strain has the subtilin genes, required for our Subtilin Production and Immunity parts.

Protocol

Please refer to: DNA extraction of Bacillus subtilis for materials required and protocol.

Results

Results were as expected see: https://2010.igem.org/Team:Newcastle/7_July_2010

Conclusion

See: https://2010.igem.org/Team:Newcastle/7_July_2010

Research

Today we also continued with our research on filamentous cells which will act as reinforcing fibres in the crack.
