[Day 2] Seeding!

The bacteria that can produce the product we want
is first removed from the freezer.
It is then grown on a selective plate (LB/AMP/Ara).
“Ara” is short for Arabinose, a monosaccharide that is used
as a carbon source for the organisms that we wanna grow.
A selective plate allows only the bacteria with the properties
we want to grow, as well as to exhibit special properties
if they have the genes that we insert into them.
Once they have been incubated for a day,
a few colonies are selected and transferred over to the flask
with the 100ml LM medium. This flask is then left at 32°C for
one day so that the colonies that have been put inside the
flask can grow.

1. Collect pGLO transformed E.Coli from the freezer.

2. Streak on a LB/Amp/Ara plate with 100mg/ml of ampicillin
and arabinose 0.2% and incubate it for 24hrs.

3. Streak colonies of pGLO transformed E.Coli from LB/Amp/Ara plate,
and transfer them to the flask containing 100ml LB medium with ampicillin.

4. Place flask in shaking incubator and incubate at 32°C
for 24 hours or at room temperature for 48 hours.
This will be used to inoculate the fermentor for scale-up fermentation.
