on 08/02/1997, [____]completed the fifteenth be
fermentation production run, which resulted in 200ml of 3.4x10*° _
spores/ml (approximately 6.8x10 total spores). During
dilutions both before and after heat shock procedures no Bacillus
globigii contamination was noted.
On 08/04/1997, [______]Jcompleted the sixteenth
fermentation production run, which resulted in 180ml of 3.1x10*°
spores/ml (approximately 5.6x10* total spores). During
dilutions before heat shock procedures three (3) colonies of
Bacillus globigii contamination were noted on one (1) dilution
plate.
On 09/09/1997,[ ____—|completed the seventeenth
fermentation production run, which resulted in 170ml of 4.6x10*°
spores/ml (approximately 7.8x10" total spores). During
dilutions before heat shock one (1) colony of Bacillus globigii
contamination was noted on one (1) dilution plate at two (2)
separate dilutions, and after heat shock procedures one (1)
colony of Bacillus globigii contamination was noted on one (1)
dilution plate.
On 09/15/1997, [_______Jcompleted the eighteenth
fermentation production run, which resulted in 180ml of 2.7x10?°
spores/ml (approximately 4.9x10¥ total spores). During
dilutions after heat shock procedures three (3) colonies of
Bacillus globigii contamination were noted on one (1) dilution
plate.
On 09/23/1997,[ _| completed the nineteenth
fermentation production run, which resulted in an unknown
quantity and an unknown concentration. No Bacillus globigii
contamination was noted during the concentration assay. The
disposition of this fermentation run is unknown, however, 70ml1 of
irradiated spores, concentration 5.0x10’ spores/ml, dated
09/23/1997 were recovered in a consensual search of the Lothar
Salomon Life Sciences Test Facility at the Dugway Proving Ground,
Dugway, Utah on 06/30/2004.
Summary of Bacillus qglobigii Contamination
Bacillus globigii contamination was noted in five
productions runs dated 06/28/1997, 07/21/1997, 08/04/1997,
09/09/1997, and 09/15/1997. All five (5)o£ these runs were sent
to Ivins at USAMRIID of which three (3) were added to a stockpile
compiled by Ivins call RMR 1029. Additionally, four (4)
productions runs, (04/18/1997, 06/23/1997, 07/01/1997,
07/29/1997) were aborted and autoclaved due_to Bacillus globigii
contamination. There is no explanation in[ si notes as toa
