Well exciting news. I made two cultures of E. Coli & Serratia marcescens on a petri dish implementing the quadrant streak method A and the radiant streak culture technique. Supposedly the way that you "smear" the bacteria onto the nutrient rich agur can affect the results making them more or less readable. So, why you ask did I choose the quadrant streak method A and the radiant streak method? (oh, you didn't ask?, well never mind I'll tell you anyway) I chose these particular culture techniques for their inherint artistic quality. After all, if you are going to grow bacteria it may as well be in an attractive pattern. After careful study of the four choices we were given, I was able to narrow it down to three (I discarded streak method b as being too disorganized to the eye), finally after realizing that the T method, while aesthetically pleasing in its neat organization, didn't really "speak" to me I was able to pass over it as well. Thus I was left with the two techniques listed above. Method A looks a bit like a work of modern art with groupings of 4-5 lines circling the plate in an ever closing space while the radiant technique is sort of the sun rise look, with the streaks flowing from a horizontal line upward to the top of the dish. Quite uplifing. I won't know until after the incubation time if I've managed to grow some nice colonies of the bacteria. I'll keep you posted though.
