Effects of environmental parameters on the formation and turnover of acetate by forest soils

Article Abstract:

The formation of acetate in forest soils in the absence of oxygen may be part of a trophic connection between aerobic and anaerobic processes in the soil. Under anaerobic conditions acetate was produced and remained stable, though was later used in the formation of methane and reduce sulfate. However, when oxygen and nitrate were present, acetate that was produced was quickly consumed, probably in aerobic respiration and denitrification.

Acetogenic and sulfate-reducing bacteria inhabiting the rhizoplane and deep cortex cells of the sea grass Halodule wrightii

Article Abstract:

Research is conducted on the bacteria enrichment extent of the sea grass rhizosphere sediments and the effect of anaerobes on the sea grass roots. Results demonstrate a possibility to design rhizosphere targeting oligonucleotide probes to localize and quantify sea grass root associated bacteria.

Physiological ecology of Clostridium glycolicum RD-1, an aerotolerant acetogen isolated from sea grass roots

Article Abstract:

Researchers describe an anaerobic hydrogen-utilizing bacterium from sea grass roots that can tolerate limited amounts of oxygen. Clostridium glycolicum RD-1 metabolizes substrates via the acetyl-CoA pathway.
