kivd adhII pdc PCR
Today we begun the trials to extract the kivd gene from Lactococcus lactis, and adhII and pdc from S.cerivase.
We will try to extract the gene from three different strains of filmjölk, a swedish dairy product similar to yoghurt; Filmjölk and Långfil from Arla, and Verum Hälsofil from Norrmejerier. The the Filmjölk contains basic fil culture, that is Lactococcus lactis subsp. lactis, Lactococcus lactis subsp. cremoris, Lactococcus lactis biovar. diacetylactis, and Leuconostoc mesenteroides subsp. cremoris. The Långfil is the same as Filmjölk but also includes three different strains of Lactococcus lacti longi. The Verum Hälsofil contains an unknown fil culture from Norrmejerier and also the Lactococcus lacti lacti L1A.
In preperation for the PCR 5 ml of filmjölk is washed five times with deionized water with 4000 g centrifub´gation in between to collect bacteria.

This morning I did the finishing step in the creation of seed stock for competent E.coli as given by: [http://openwetware.org/wiki/TOP10_chemically_competent_cells ]. Depatures from protocol in this step was the use of E-tubes instead of cryo tubes for the storage of the seed stock. We'll just have to avoid dropping the frozen tubes ;)
