I have been freeze drying my E.coli in eppendorf tubes and when it comes out all at once it looks a bit like a bullet or a stick of lipstick because of its red colour. I though this was quite funny as my friend Adele has been making poo shaped lipstick as part of her [...]
I decided to try extracting some collagen from a kangaroo tail yesterday. It turned out to be very similar to a rats tail in structure but of course many times larger with much bigger tendons. This morning when I went to check on the tendons stirring in Acetic acid they had swelled up so much [...]
I was showing new SymbioticA resident Jenny Boulboulle my freeze dried E.coli and we were talking about how strange it was that this seemingly lifeless material actually contained the potential to be reconstituted into thousands of bacteria. To test this I put a fragment of the freeze dried bugs into media and incubated it overnight [...]
I did my first evaporation of the rats tail collagen extract into a film yesterday. I squeezed the gelated collagen out of the dialysis tubes into a dish and left it in a drying oven at 50 degrees Celsius overnight. When I pulled it out of the oven it looked like this: You can see [...]
Well I took my first lot of freeze dried E.coli off the freeze drier this morning. I experimented with two methods – scraping the bugs off the media plates, or using the liquid culture. I found that to filter the liquid culture was virtually impossible (I have since learned that you need to centrifuge it [...]
Today I was streaking some more E.coli and I noticed the way in which the bugs from last week had sucked up all the red mineral salts from the media. When the salts run out the media returns to a translucent yellowish colour.
