THE ROLE OF ANAEROBIOSIS IN ASYMBIOTIC NITROGEN FIXATION
Canadian Journal of Microbiology, 1967Microbial fixation of atmospheric nitrogen was measured in soil amended with ground wheat straw and incubated at two moisture levels (field capacity and waterlogged). Fixation equivalent to 42–52 kg/ha in the soil at field capacity and 13–150 kg/ha in the waterlogged soil was observed using 15N techniques when the soil was amended with 1% straw or ...

Myocardial anaerobiosis in anemia in ur?mic man
The American Journal of Cardiology, 1972Myocardial anaerobic metabolism (lactate production) has been previously observed in man primarily in ischemic heart disease. Myocardial lactate balance was studied in severe anemia in 6 stable uremic patients receiving maintenance hemodialysis before and after transfusion.

Ethidium bromide mutagenesis in yeast: Protection by anaerobiosis
Mutation Research/Fundamental and Molecular Mechanisms of Mutagenesis, 1975The mutagenesis by ethidium bromide, an intercalating dye, which induces the mutation from wild type (rho+) to the cytoplasmic respiratory deficient petite (rho-) in Saccharomyces cerevisiae, was studied under aerobic and anaerobic conditions. During growth of anaerobic cells at pH 6.5, ethidium bromide at a concentration of 2 mug/ml is unable to ...

The Use of Microbial Membranes to Achieve Anaerobiosis
Critical Reviews in Biotechnology, 1990The cytoplasmic membranes of many aerobic and facultative bacteria contain enzymes that catalyze the reduction of dissolved oxygen to water. Preparations of small particles derived from such membranes can be filter sterilized without loss of the oxygen-reducing enzymes.

The effect of anaerobiosis on the origin of respiratory-deficient yeast
Experimental Cell Research, 1957Abstract Respiratory-sufficient (AER) haploid yeast cells were subjected to aerobic and anaerobic conditions to determine whether anaerobiosis transforms respiratory-sufficient cells into respiratory-deficient (aer) cells. Anaerobiosis in the absence of growth failed to increase the frequency of aer cells.

The Uses of Anaerobiosis by Amphibians and Reptiles
American Zoologist, 1985Amphibians and reptiles rely upon anaerobic glycolysis to support their energetic requirements under a variety of circumstances. Although adult frogs derive most of the energy for muscle contraction during intense, short-term locomotion from glycolysis, anuran tadpoles have a very low rate of lactate formation during 30 sec of burst swimming; instead ...

Effect of Local Anaerobiosis on Heart Rate
1990The isolated leg of a rat was connected to the body only by nerve and bone and was perfused with hypoxic Tyrode solution. Heart rate increased when metabolic parameters (PCO2, pH and lactate) reached values similar to those observed at the beginning of exercise.
