Trying to produce Venom from Bacteria by plasmid insert Trying to produce Venom from Bacteria by plasmid insert Hello, My idea is trying to produce venom by inserting the gene for the venom into a K12 strain of E. Coli bacteria. I would be following a method similar to that of the PGLO lab (the only difference here would be the gene that was added would be of the venom instead of a glowing protein).

Matching nutrient ppm in soil Matching nutrient ppm in soil Hi all! For my experiment, I'm comparing vermicompost tea and Miracle Gro water soluble fertilizers in terms of nitrogen runoff in soil. So ideally, I want the nitrogen ppm of the vermicompost tea and the water soluble tea to be the same. In order to find the nitrogen ppm of vermicompost, I added 1 part of solid vermicompost to 5 parts water, waited for the sediment to settle, and tested the solution. The test told me that the… Read more
