There has been overgrowing a hybrid of organisms, but assumingly the pinky/white powdery dots are streptomyces colonies. Such colonies are mostly to be found on the 1:100 and 1:1000 dilution plates. Only one sample has been contaminated, as it was the first one to get done during the isolation process. | There has been overgrowing a hybrid of organisms, but assumingly the pinky/white powdery dots are streptomyces colonies.Such colonies are mostly to be found on the 1:100 and 1:1000 dilution plates. In this case, creating subcultures is the best solution, in order to get a unified-type of biotope in the petri dish! | ||
