pH changing
We brought hepes (which is similar to homopipes) to pH 7 then autoclaved it.
Preparing medium for natto
We prepared antibitoic ,medium for natto: 17.5g of broth in 1L, so 1.75 in 100ml
Extreme Overnight cultures for Gibson

Transformation of Bacillius subtilis 168 with pGFP-rrnB containing yneA
Aim
The aim of the experiment is to perform insert the plasmid pGFP-rrnB containing yneA which have been ligated eariler into the chromosome of Bacillus subtilis 168. B. subtilis containing the intergated vector will be resistance to both the antibiotics chloramphenicol and streptomycin, therefore those that have successful intergated will be selected with agar plates that contain both the antibiotics. The second step will be to identify those colones that have the plasmid intergated at the corerct position in the chromosome, which is the amylase gene locus. Thus those that have intergrated at the wrong position will not be able to break down starch, which can be tested with the iodine test.
Materials and Protocol
Please refer to: Transformation of Bacillus subtilis Note: Overnigth culture of B. subtilis 168 in MM competence medium was done the day before and the iodine test was performed the day after transformation.
