During oxygen limitation in animals, glucose can be fermented via several metabolic pathways varying in energetic efficiency and leading to various end products (such as lactate, alanopine, octopine, succinate, or propionate). Because of opposite p H dependencies of proton production by fermentation and by ...

Invertebrate Facultative Anaerobiosis
Science, 1972The unique pattern of anaerobic carbohydrate metabolism in invertebrate facultative anaerobes serves to couple other substrate-level phosphorylations to the glycolytic reactions, thus increasing the potential yield of high-energy phosphate compounds. Currently, two important coupling sites can be identified:

Plant responses to anaerobiosis
Plant Science, 1993Abstract Plant life is greatly impaired under conditions of oxygen deficit. Only few plants can grow in waterlogged soils, thanks to anatomical adaptation allowing the transport of oxygen to the submerged parts of the plant. The behaviour of a few plant species able to germinate under completely anoxic conditions can be explained only by assuming ...

"Excess Lactate" and Anaerobiosis
Annals of Internal Medicine, 1963Excerpt Huckabee (1) has appraised anaerobic metabolism in whole animals and in intact organs by determining the ratio of lactate to pyruvate concentrations in plasma, and by calculating "excess la...

OBSERVATIONS in estuaries have reported the existence of ephemeral deposits of semi-fluid mud1,2 extending several metres from the bottom. These muds differ from ‘mud’ as normally understood in that although they form definite boundaries with the overlaying water mass they have a lower solid content and settle, if at all, only very slowly.

Effects of anaerobiosis on bacteriophage synthesis
Archives of Biochemistry and Biophysics, 1957Abstract 1. 1. Studies have been made of the multiplication of several coliphages on E. coli grown under aerobic and anaerobic conditions. 2. 2. With aerobically grown E. coli , synthesis of phages T1, T2r, T2r + , and T4r + takes place equally well under both aerobic and anaerobic conditions. 3. 3. With anaerobically grown E. coli ,

Anaerobiosis and Sodium Accumulation
Nature, 1961ACCUMULATION of most cations by higher plants is considered to be an aerobic process. However, we now find that sodium is in part an exception to this generalization. Uptake of sodium by 6-day old plants of Hordeum vulgare, variety Atlas 46, occurs under both aerobic and anaerobic conditions.

Soil wetness brings to mind thoughts about the soil water regime as a soil classification parameter and about artificial drainage systems to moderate the frequency and duration of occurrences of excessive soil wetness related to high water table or saturated soil conditions.

Anaerobiosis in the nematode Caenorhabditis elegans
Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 1999In Caenorhabditis elegans, mortality rates and changes in concentrations of carbohydrate stores and anaerobic end products were determined in anoxic (test) and normoxic (control) animals at two different temperatures (10 and 20 degrees C). The anoxic tolerance of the free-living nematode proved to be well-developed: at 10 degrees C, about 50% of ...
