Methylated arsenic (As) species represent a significant fraction of the As accumulating in rice grains, and there are geographic patterns in the abundance of methylated arsenic in rice that are not understood. The microorganisms driving As biomethylation in paddy environments, and thus the soil conditions conducive to the accumulation of methylated arsenic, are unknown. We tested the hypothesis that sulfate-reducing bacteria (SRB) are key drivers of arsenic methylation in metabolically versatile mixed anaerobic enrichments from a Mekong Delta paddy soil. We used molybdate and monofluorophosphate as inhibitors of sulfate reduction to evaluate the contribution of SRB to arsenic biomethylation, and developed degenerate primers for the amplification of arsM genes to identify methylating organisms. Enrichment cultures converted 63% of arsenite into methylated products, with dimethylarsinic acid as the major product. While molybdate inhibited As biomethylation, this effect was unrelated to its inhibition of sulfate reduction and instead inhibited the methylation pathway. Based on arsM sequences and the physiological response of cultures to media conditions, we propose that amino acid fermenting organisms are potential drivers of As methylation in the enrichments. The lack of a demethylating capacity may have contributed to the robust methylation efficiencies in this mixed culture.

IntroductionAliphatic cellular polyamines, linear diamines, triamines, tetra-amines, penta-amines and hexa-amines, and quaternary branched penta-amines, were found in eubacteria (domain Bacteria) and archaebacteria (doPolyamine analysis for chemotaxonomy of thermophilic eubacteria:Polyamine distribution profiles within the orders Aquificales, Thermotogales, Thermodesulfobacteriales, Thermales, Thermoanaerobacteriales, Clostridiales and Bacillales Cellular polyamines of 45 thermophilic and 8 related mesophilic eubacteria were investigated by HPLC and GC analyses for the thermophilic and chemotaxonomic significance of polyamine distribution profiles. Spermidine and a quaternary branched penta-amine, N 4 -bis(aminopropyl)norspermidine, were the major polyamine in Thermocrinis, Hydrogenobacter, Hydrogenobaculum, Aquifex, Persephonella, Sulfurihydrogenibium, Hydrogenothermus, Balnearium and Thermovibrio, located in the order Aquificales. Thermodesulfobacterium and Thermodesulfatator belonging to the order Thermodesulfobacteriales contained another quaternary penta-amine, N 4 -bis(aminopropyl)spermidine. In the order Thermotogales, Thermotoga contained spermidine, norspermidine, caldopentamine and homocaldopentamine. The latter two linear penta-amines were not found in Marinitoga and Petrotoga. In the order Thermales, Thermus and Marinithermus contained homospermidine, norspermine and the linear penta-amines. Meiothermus lacked penta-amines. Vulcanithermus contained linear penta-amines and hexa-amines but not homospermidine. Oceanithermus contained spermine alone. Within the order Thermoanaerobacteriales, the two quaternary branched penta-amines were found in Thermanaeromonas and Thermoanaerobacter. Caldanaerobacter contained N 4 -bis(aminopropyl)spermidine. Thermoanaerobacterium lacked penta-amines. Thermaerobacter of the order Clostridiales contained N 4 -bis(aminopropyl)spermidine and agmatine. Thermosyntropha, Thermanaerovibrio, Thermobrachium (the order Clostridiales), Sulfobacillus, Alicyclobacillus, Anoxybacillus, Ureibacillus, Thermicanus (the order Bacillales), Desulfotomaculum, Desulfitobacterium and Pelotomaculum (the family Peptococcaceae) ubiquitously contained spermine. Some thermophiles of Bacillales added linear and branched penta-amines.

We previously reported ionic binding cellular polyamines extracted into 0.5 M perchrolic acid (PCA) and total polyamines detected in 6 M HCl-hydrolysate of the whole cells in various anaerobes with Gramnegative cell walls, belonging to the Sporomusa subbranch (Sporomusa-Pectinatus-Selenomonas phyletic group) (Hamana, 1999). The occurrence of covalently linked putrescine and/or cadaverine in cell wall, nonextractable with 0.5 M PCA from cells, was suggested within the major members of this subbranch, viz. the genera Acetonema, Sporomusa, Megasphaera, Selenomonas, Veillonella, Pectinatus, Dialister, Acidaminococcus, Zymophilus, and Anaerovibrio (Hamana, 1999). Furthermore, a part of cellular spermidine of Selenomonas dianae, Selenomonas infelix, and Acidaminococcus fermentans was not extracted with 0.5 M PCA from the cells, suggesting the occurrence of covalently linked spermidine in their cell walls (Hamana, 1999). In the present study, cell wall peptidoglycan was prepared from seven Selenomonas species, Acidaminococcus fermentance, Anaerovibrio lipolyticus (formerly Anaerovibrio lipolytica) and two newly validated species, Anaeromusa acidaminophila (formerly Selenomonas acidaminophila) (Baena et al., 1999) and Dendrosporobacter quercicolus (formerly Clostridium quercicolum) (Stompl et al., 2000) phylogenetically located in the Sporomusa subbranch.The organisms were grown anaerobically in the anaerobic culture medium, GAM broth (Nissui Pharmaceutical Co., Tokyo, Japan), at 37°C. Peptidoglycan was prepared by two procedures, SDS-Trypsin method and SDS-Amylase method, according to Braun and Sieglin (1970) and Kamio et al. (1981b), respectively. Hydrolysis of the peptidoglycan fraction with 6 M HCl at 110°C for 20 h was carried out before high performance liquid chromatography (HPLC) on an Hitachi L6000 high-speed liquid chromatograph as described previously (Hamana, 1994). Agmatine was identified by alkaline hydrolysis with 1 M NaOH at 110°C for 20 h to convert agmatine into putrescine. PCA extractable polyamines from whole cells and polyamines in the 6 M HCl-hydrolysates of cellresidues (after five-fold extractions with 0.5 M PCA until polyamines were not detected in the PCA extracts) (Hamana, 1999), were also determined in the organisms.PCA-soluble cellular polyamines (PCA) and released polyamines by the acid hydrolysis from the cell residue after the PCA-extract (HCl-Res) estimated per wet cell weight are shown in
