“…Aggregates of globular Fe‐oxyhydroxides are generally assumed to form by abiotic oxidation (Boyd & Scott, ), but the associated nest and tube features display morphological traits that may be linked to microbial activity. The fibrillar, rounded nests found in low abundance in the JMVF chimney (Figure g) resemble capsules formed by freshwater Fe oxidizers belonging to the Siderocapsa group (Hanert, ). Similar nests have also been detected in low‐temperature hydrothermal Fe deposits at the Loihi Seamount and ascribed to Fe‐oxidizing secondary colonizers (Chan, McAllister, et al, ).…”

“…Many neutrophilic iron-oxidizing bacteria are still poorly defined due to the lack of pure cultures and nonspecific morphologies, e.g., many species in the Siderocapsaceae family (22,23,43). A number of the sequences (1.73 to 26.5%) derived from the three red water libraries in the current study showed moderate similarity to both Sideroxydans strains and Gallionella sequences, suggesting that these sequences may be representative of novel circumneutral-pH, microaerobic, iron-oxidizing bacterial species within this particular water distribution system.…”

“…Sample material collected aseptically with alcohol and flame sterilized spatulas from spring deposits in the 2006 field season was used to inoculate sulfide gradient tubes on return to the laboratory. Gradient tubes were assembled using iron sulfide plugs created by adding FeS precipitate prepared according to the method of (Hanert, 2006) in a 1:1 ratio with EM media (see below) and high melt agarose (1% wt/vol) in a flask. 1 mL aliquots of the autoclaved plug material were allowed to cool in 10 mL glass tubes and covered by 5 mL of a semi‐solid agar slush overlayer (0.15 wt/vol agarose) of an autoclaved, artificial seawater medium (EM) containing 27.5 g NaCl, 5.38 g MgCl 2 , 0.72 g KCl, 0.2 g NaHCO 3 , 1.4 g CaCl 2 , 1 g NH 4 Cl, and 0.05 g K 2 HPO 4 , dissolved above in 967 mL deionized H 2 O.…”
