Homemade 

Solid Culture Media 


Away from the laboratory, I was curious to create agar plates with ingredients that we can find in our kitchen. 


Ingredients

    • 2g Table Salt (NaCI)
    • 300 ml of boiling water
    • 1.5g Yeast extract paste
    • 6.25g Gelatine
    • Sterile Plastic Petri Dishes


Procedure 

First, mix the table salt with the water. Allow the table salt to melt to create a solution. 

Second, add the yeast extract to the solution. Mix it until it is dissolved. 

Third, add the gelatine to the solution. Mix it until the lumps disappear.

Plate

    Pour the solution into the dishes very carefully to avoid bubbling. From the solution, 15 plates of 20 grams each are obtained.



Conclusion

To conclude, with these procedures agar plates can be created at home. It does not mean that these culture media can sustain bacteria such as E.coli and D. radiodurans. I haven't put them into practice yet, but I'm excited to see if I can get bacteria growth on these homemade agar plates...

    I did the very same thing! This totally cracked me up. I love it. Hope you had fun!!

   Understanding electrophoresis  For this blog, I wanted to practice electrophoresis, but since I don’t have the lab equipment I wanted to try a DIY experiment. I researched experiments that can be done in the home, and I found a great one that would help me understand a little bit better how electrophoresis works. In this experiment, I will be able to visualize how food color is separated with the help of the electrophoresis. First, I set up my electrophoresis chamber with a plate and a hair comb to form my sample walls.  Second, I made the gel with 200 ml of water, 0.4 grams of baking soda, and 2 grams of agar. The agar was the most difficult ingredient to find. Luckily, I found it on amazon. Like in the lab I proceeded to mix the ingredients, then I heated the solution in the microwave for one minute. I let the solution to cool down for 15 minutes before pouring it into my electrophoresis chamber. Then, I waited an hour for the solution to solidify. After an hour...

Bacteria in my daily life For this blog I choose to talk about E. Coli since in my previous blog I talked about Deinococcus radiodurans. I recently became interested in learning more about other bacteria such as E. coli. I will provide a little background on why I decided to talk about E. Coli. I work in the food industry in a fast food restaurant. I was required to obtain a food handler card. During my training, I learned how easily food can be contaminated especially, if people do not know how to properly prepare food. I believe that being aware of the science behind cooking would be more beneficial if this training was accessible to more people.  In a common household like mine (I share a house with my siblings) cross contamination can occur because they do not have the knowledge on how to properly handle food, for example when cooking  meat and vegetables. For instance, when they cook they do not pay much attention that they often use the same cutting board for different...

  Deinococcus Radiodurans and its Guinness World Record I am pleased to present a few interesting facts about Deinococcus radiodurans ( D. radiodurans) . D. radiodurans were discovered in 1956 by Professor Arthut W. Anderson in Oregon Agricultural Experiment Station, Corvallis Oregon. While Arthur W. Anderson was sterilizing canned meat to omit its decomposition; the emergence of various reddish colonies made a presence. One may wonder how something like this could have happened? The explanation for such an event is that the meat cans were exposed to high doses of radiation; These high temperatures of radiation were supposed to be enough to eliminate all known forms of life. For this reason, this bacterium should be given the appropriate name that would honor its ability to survive in extreme conditions. These radiation-resistant organisms were granted with the name of Deinoccocus Radiodurans. D. radiodurans literally means the "strange battle that endures radiation."  D. rad...
