Abstract
Ar.se.ni.ci.coc'cus. L. n. arsenicum arsenic; N.L. masc. n. coccus berry (from Gr. masc. n. kokkos grain, seed), N.L. masc. n. Arsenicicoccus arsenic coccus, because the type species was recovered from an arsenic enrichment).
Actinobacteria / Actinobacteria / Micrococcales / Intrasporangiaceae / Arsenicicoccus
Cells are cocci that occur in clusters. Gram-stain-positive and nonsporeforming. Facultatively anaerobic and catalase-positive. Acid is formed from glucose and some other carbohydrates. Nitrate is reduced. Voges–Proskauer-negative. The major long-chain cellular fatty acids are a complex mixture of straight-chain saturated, monounsaturated, iso- and anteisomethyl-branched acids. Hydroxy fatty acids are not present. The major respiratory quinone is MK-8(H4 ). Cell-wall murein is based on ll-diaminopimelic acid (type: ll -Dpm-glycine1 ). Isolated from arsenic enrichment from sediment containing mine waste (Adak, Boliden region, Sweden).
DNA G+C content (mol%): 72.2.
Type species: Arsenicicoccus bolidensis Collins, Routh, Saraswathy, Lawson, Schumann, Welinder-Olsson and Falsen 2004, 608VP.
