Long-term anaerobiosis in sublittoral marine invertebrates from the Western Baltic Sea: Halicryptus spinulosus
Long-term anaerobiosis was studied in the priapulid Haljcryptus spinulosus and the bivalves Astarte borealis and Arctica island~ca, species with an extremely high resistance to lack of oxygen, from Kiel Bight. This shallow, brackish environment is frequently affected by extended periods of oxygen deficiency. Animals were experimentally subjected to anoxia for up to 60 d. Glycogen was the most i...
متن کاملThe Biochemistry of Anaerobiosis
To live anaerobically an organism must generate its energy and synthesize its substance without recourse to molecular 02. Thus any discussion of the biochemistry of anaerobiosis must centre on what alternatives there are to aerobic respiration and oxygenic photosynthesis as means of biological energy conservation, and to what extent an anaerobe is constrained by being denied the facility of exp...
متن کاملStreptomycin Action and Anaerobiosis.
The question was asked whether the insensitivity to dihydrostreptomycin and streptomycin exhibited by facultatively anaerobic organisms growing strictly anaerobically could be due entirely to the lack of an anaerobic mechanism for the uptake of these antibiotics. A technique is described here which allows exposure of Escherichia coli B to dihydrostreptomycin, under conditions which are known to...
متن کاملZoology: Invertebrates that Parasitize Invertebrates
The genome of an orthonectid, a group of highly modified parasitic invertebrates, is drastically reduced and compact, yet it shows the bilaterian gene toolkit. Phylogenetic analyses place the enigmatic orthonectids within Spiralia, although their exact placement remains uncertain.
متن کاملUnsuspected pyocyanin effect in yeast under anaerobiosis
The blue-green phenazine, Pyocyanin (PYO), is a well-known virulence factor produced by Pseudomonas aeruginosa, notably during cystic fibrosis lung infections. It is toxic to both eukaryotic and bacterial cells and several mechanisms, including the induction of oxidative stress, have been postulated. However, the mechanism of PYO toxicity under the physiological conditions of oxygen limitation ...
