Incubation of 3-d-old seedlings of Oryza sativa L. cv Arborio under anaerobic conditions, leads to a large increase in the titer of free putrescine while aerobic incubation causes a slight decrease. After 2 days, the putrescine level is about 2.5 times greater without oxygen than in air. The rice coleoptile also accumulates a large amount of bound putrescine and, to a lesser extent, spermidine ...

The strictly anaerobic metabolism of sugar in strains of Streptococcus mutans and Streptococcus sanguis was studied because deep layers of dental plaque are strictly anaerobic. Galactose-grown cells of these streptococcal strains had higher pyruvate formate-lyase activity than did glucose-grown cells. Among these strains, two strains of S. mutans had a significantly higher pyruvate formate-lyas...

Pseudomembranouscolitis is one of the serious infectious diseases with a high mortality. It tends to occur in association with antibiotic therapy, especially with broad spectrum antibacterial agents. The major causative pathogen is the anaerobic bacterium Clostridium difficileP This bacterium is extremely sensitive to oxygen, and requires strict anaerobic conditions for growth. Once exposed to ...

The anaerobic incorporation of 32P into ATP by the tapeworm Hymenolepis diminuta was studied in the presence and absence of uncouplers of oxidative phosphorylation and anticestodal agents. Low concentrations of all compounds tested inhibited this incorporation. Under the anaerobic conditions employed, internal ATP concentrations remained constant in spite of the inhibition of the incorporation ...
