State or that the dominant hydrogen-using acetogens present in soil and litter are not spore formers (Kusel et al. 1999a). 

Perform resistance testing on all Gram-positive spore formers. Submit any organism surviving the resistance test for D-value determination. 5. Summarize stopper and vial data separately. 

Conventional tin and glass containers can be satisfactorily treated by steam or hot air. Paper, cardboard, and heat-sensitive plastics require subtler techniques. Experiments with Co60 gamma rays indicate that 200,000 r. are sufficient to inactivate vegetative contaminants, while the customary 2 X 10 r. are required for spore formers. These doses are considerably below those that would be expected to have any effect on the physical properties of these materials (Sec. IIIC5).

The organism most resistant to steam heat is the bacterial spore former B. stear-othermophilus. Other indicator organisms have been employed, but B. stear-othermophilus spores are by far the most commonly used Bis in validating steam sterilization cycles. 

The casein retentate, when used as cheese milk, can almost be fully depleted of all whey proteins through a sufficient number of diafiltration volume turnovers. In contrast to conventional cheese technology, it is then possible to UHT treat the cheese milk in order to destruct spore formers. The whey proteins can be used as a WPG or WPI product or treated further in order to fractionate the whey proteins in their main components. Alternatively the whey proteins can particulated to form WPP see Section 19.5.1. Both approaches are options to build a platform for novel product matrices with specific properties such as gelling, foaming or emulsification. 

However, Bacillus anthracis, the causative agent in inhalation anthrax, still remains the premier bioterrorist threat today. The Bacillus anthracis spore is nearly ubiquitous in nature and is not terribly difficult to isolate and grow. Being a spore former, the anthrax bacterium can withstand environmental stress while maintaining its virulence, as well as being hardy enough to withstand chemicals, UV light, and processes used in its weaponization. Finally, especially nowadays, the word anthrax alone strikes a fearsome chord in most people. 

These aerobic spore formers resemble the common soil organism, Bacillus cereus Fr. and Fr., very closely indeed.
