The tubes were weighed and estimated to contain about[ | of material each. To each tu bb f sterile water for injection was added to the material. After thorough mixing, the material was transferred to a second tube. The original tube was disinfected with bleach, dried and weighed. The net weight of the granular material was then determined and listed above. Ten-fold dilutions of the suspensions were plated out onto TSA, then incubated overnight.
