V-B 21 June 95 - Dried powder from spray drier - 0.00639g 7. 1V-B Bentonite feed stock - 0.00865 g | received the| samples (in small cryotubes in a ziplock bag) from n the afternoon of 24 October, 2001. The tubes were weighed and estimated to contain about|___Jof material each. To each tube bt 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. Plate counts were made, and the following concentrations were determined for the material: Samples: 4. VIII-B 21 June 95 - Dried BT powder - -1X 10° CFU per gram a 2. VII-B Spray drier - BT 2.2 X 10" CFU per gram 3. 1-B Dried powder : 1.0 X 10’ CFU per gram 4. IX-B Spray-dried BT 9.5 X 10° CFU per gram 5. VI-B Dried powder from fermentor run 1.3 X 10" CFU per gram 6. V-B 21 June 95 - Dried powder from spray drier 5.0 X 10° CFU per gram
