anaerobic respiration by Escherichia coli K-12," Journal of Bacteriology, vol.
On the other hand, the highest TSS in sealed packages (0 perforations) could be due to the induction of
anaerobic respiration due to very low levels of oxygen in the package atmosphere, as indicted by Saquet and Streif (2008).
organic acids), (iii) increase in biomass of microorganisms; (iv) denitrification and (v)
anaerobic respiration of sulfate.
During
anaerobic respiration, oysters produce alanine and succinate, which although still acidic may be more advantageous for acid--base balance compared with the typical mammalian anaerobic end product of lactate (Collicutt & Hochachka 1977, Hochachka 1980, Eberlee & Storey 1984, Storey 1993).
The by-product of this
anaerobic respiration is hydrogen sulphide which is toxic to everything, except the bacteria, and is characterised by the odour of rotten eggs.
The acute respiratory alkalosis may be accompanied by a metabolic acidosis if the hypoxia is severe enough to cause the buildup of lactic acid resulting from
anaerobic respiration.
ADH is an enzyme that acts on the respiratory process by removing toxic substances, such as acetaldehyde and ethanol, produced when cells start
anaerobic respiration (FARIA et al., 2003).
At the bottom of the ocean and in other places with no oxygen, organisms get their energy instead using substances such as nitrate or sulfur to synthesize ATP, much the way organisms did many billions of years ago ("
anaerobic respiration").
Anaerobic respiration produces chemicals that have foul odor and unpleasant taste and, generally, renders such a water body hazardous for any form of human usage.
