Streptomyces and Antibiosis
From our group, Group 2, nutrient agar plates inoculated with E. Coli, (Images 1.1,1.2), (Images 2.1,2.2), (Images 3.1,3.2) no antibiotic activity was detected. This could be a result of the putative colonies chosen, not being Streptomyces. All selected colonies were white, or pigmented rink, raised and rough. One (1) and three (3) were inoculated with the putative Streptomyces colonies. Plate 2 was inoculated with the control Streptomyces colony. Although it was determined that the activity of antibiotics was inconclusive no raised colonies were visible although then nutrient agar appeared to be texture. Errors were made when plating. When the first molten agar was poured, the agar did not solid uniformly due to agitation. Also, when the Streptomyces was played a separate plate for the control Streptomyces and comparison of experimental Streptomyces and control …show more content…
The Instead, two (2) plates, the unevenly poured plate and an additional plate were inoculated with the experimental Streptomyces and a third plate was inoculated with the control Streptomyces. To make observations and draw conclusions, plates of Group 1 (Images 4.1,4.2) (Images 5.1,5.2) Other errors occurred during the incubation and storage of the nutrient agar plates. In addition to this, samples of Streptomyces were originally planned to be taken from the 10-6 dilution plate. In transfer from the incubation plate to the inoculation plate, two (2) sample Streptomyces colonies fell onto the bench. Colonies from the 10-4 dilution were then
