Factors affecting denitrification and anammox rates in tidal flat sediments

Denitrification prevails over anammox in tropical mangrove sediments (Goa, India).

Denitrification, anammox (Anx) and di-nitrogen fixation were examined in two mangrove ecosystems- the anthropogenically influenced Divar and the relatively pristine Tuvem. Stratified sampling at 2 cm increments from 0 to 10 cm depth revealed denitrification as the main process of N₂ production in mangrove sediments. At Divar, denitrification was ∼3 times higher than at Tuvem with maximum activi...

Anammox, denitrification and DNRA in the East China Sea sediment

Denitrification pathways and rates in the sandy sediments of the Georgia continental shelf, USA

A prospective randomised multicentre clinical study was undertaken for 2 years and 3 months from November 1982, with the aim of examining the significance of using a combination of ftorafur (FT) and tamoxifen (TAM) for post-operative adjuvant therapy of breast cancer. Patients had either stage II or stage Illa disease, were age 75 or below and had undergone radical mastectomy. Patients were div...

Meiofauna increases bacterial denitrification in marine sediments

Denitrification is a critical process that can alleviate the effects of excessive nitrogen availability in aquatic ecosystems subject to eutrophication. An important part of denitrification occurs in benthic systems where bioturbation by meiofauna (invertebrates <1 mm) and its effect on element cycling are still not well understood. Here we study the quantitative impact of meiofauna populations...
