“…Previous studies had showed that the reoxidation of Fe(II) is not limited to O 2 in anoxic sediments (Straub et al 1996;Roden et al 2004;Melton et al 2012). Fe(II) can also be oxidized with NO 3 -as the electron acceptor (Straub et al 2001;Oshiki et al 2013). Microbialcatalyzed NO 3 --dependent Fe(II) oxidation has the potential to accelerate the dynamic of microbially mediated Fe redox cycling in anoxic sediments (Straub et al 1996;Weber et al 2006).…”

Abstract:In lake sediments, iron (Fe) is the most versatile element, and the redox cycling of Fe has a wide influence on the biogeochemical cycling of organic and inorganic substances. The aim of the present study was to analyze the vertical distribution of Fe and Fe(III)-reducing bacteria (FeRB) in the surface sediment (30 cm) of Lake Donghu, China. At the 3 sites we surveyed, FeRB and Fe(II)-oxidizing bacteria (FeOB) coexisted in anoxic sediments. Geobacter-related FeRB accounted for 5%-31% of the total Bacteria, while Gallionella-related FeOB accounted for only 0.1%-1.3%. A significant correlation between the relative abundance of poorly crystalline Fe and Geobacter spp. suggested that poorly crystalline Fe favored microbial Fe(III) reduction. Poorly crystalline Fe and Geobacter spp. were significantly associated with solid-phase Fe(II) and total inorganic phosphorus levels. Pore water Fe(II) concentrations negatively correlated with NO 3 -at all sites. We concluded that Geobacter spp. were abundant in the sediments of Lake Donghu, and the redox of Fe might participate in the cycling of nitrogen and phosphorus in sediments. These observations provided insight into the roles of microbial Fe cycling in lake sediments.
