An index which expressed the aerobic to anaerobic potential was made for bacteria with intermediate tolerance for oxygen. One method used for this analysis was measurement of the relative bacterial growth ratio. The other method was based on the pattern of the absorbancy versus depth plot. The index was applied to oral indigenous anaerobes.

Putrefactive anaerobe no. 3679 has been widely used as a test organism in thermal resistance studies. The choice of media for spore production, spore count determinations, and thermal resbtance studies has been varied by practically all workers employing this organism. Since an accurate estimation of thermal resistance is dependent upon a knowledge of the number of spores initially present, it ...

Catellicoccus marimammalium is a relatively uncharacterized Gram-positive facultative anaerobe with potential utility as an indicator of waterfowl fecal contamination. Here, we report an annotated draft genome sequence that suggests that this organism may be a symbiotic gut microbe.

we soon found that the obligatory anaerobic bacterium C. tetanomorphum is not suitable for our study, because it is not easy to keep under anaerobic conditions even with a few liters of culture broth.Thus, we decidcd to screen for ncw microbial strains that are easy to handle and produce high MAL activity. This report dealg with the first isolation of MALproducing facultative anaerobic strains ...

Yesair's pork infusion medium, as modified by Wynne and Foster (1948), has been extensively employed in thermal resistance studies of spores of Clostridium species. While this medium is excellent for the recovery of spores of these organisms, it is expensive and laborious to prepare. Recent unpublished data in this laboratory have demonstrated that counts of heat-activated spores of Putrefactiv...

Caloramator celer strain JW/YL-NZ35 is a Gram-positive thermophilic, alkalitolerant, and strictly anaerobic bacterium capable of producing hydrogen and ethanol under extreme conditions. The draft genome sequence presented here will provide valuable information to further explore the physiology of this species and its potential for biofuel production.
