[Ab] Resumo:Aminobacter sp. MSH1 is of interest for bioaugmentation of biofiltration units in drinking water treatment plants (DWTPs) due to its ability to degrade the groundwater micropollutant 2,6-dichlorobenzamide (BAM). Using a continuous flow chamber biofilm model, MSH1 was previously shown to colonize surfaces and degrade BAM at trace concentrations as low as 1 µg/L under the oligotrophic conditions found in DWTPs. In DWTP filtration units, MSH1 has to compete with the resident biofilm microbiota for space and nutrients. Using the same model, we examined how a sand filter community (SFC) affects MSH1's BAM-degrading activity and biofilm formation under C- and N-limiting conditions when fed with trace concentrations of BAM. MSH1 was inoculated simultaneously with the SFC (co-colonization mode) or after the SFC formed a biofilm (invasion mode). MSH1 successfully established in the SFC biofilm showing growth and activity. In co-colonization mode, MSH1 decreased in number in the presence of the SFC and formed isolated colonies, while specific BAM-degradation activity increased. In the invasion mode, MSH1 also decreased in numbers in the presence of the SFC but formed mixed colonies, while specific BAM degradation was unaffected. Our results show that MSH1 invades and performs successfully in an SFC biofilm under the oligotrophic conditions of DWTPs.

[Ti] Título:Degradation of methomyl by the combination of Aminobacter sp. MDW-2 and Afipia sp. MDW-3.

[Ab] Resumo:Methomyl (S-methyl N-(methylcarbamoyloxy) thioacetimidate) is a kind of oxime carbamate insecticide. It is considered to be extremely toxic to nontarget organism. To date, no pure culture or consortium has been reported to have the ability to degrade methomyl completely. In this study, a methomyl-degrading enrichment E1 was obtained by using the sludge from the wastewater-treating system of a pesticide manufacturer as the original inoculant. Two bacterial strains named MDW-2 and MDW-3 were isolated from this enrichment, and they were preliminarily identified as Aminobacter sp. and Afipia sp. respectively. Strains MDW-2 and MDW-3 could coexist and degrade 50 mg l methomyl completely within 3 days by the cooperative metabolism. Methomyl was first converted to methomyl oxime and methylcarbamic acid by strain MDW-2, and the latter could be used as the carbon source for the growth of strain MDW-2. But methomyl oxime could not be sequentially degraded by strain MDW-2. However, it could be degraded and used as the carbon source by strain MDW-3. SIGNIFICANCE AND IMPACT OF THE STUDY: This study presents a bacterial combination of Aminobacter sp. MDW-2 and Afipia sp. MDW-3, which could degrade methomyl completely by biochemical cooperation. This study also proposes the biodegradation pathway of methomyl for the first time and highlights the application potential of a bacterial combination in the remediation of methomyl-contaminated environments.

[Ab] Resumo:The genetic diversity of bacterial populations nodulating in five geographical sites from northern Tunisia was examined. Phylogenetic analyses of 50 isolates based on partial sequences of and grouped strains into seven clusters, five of which belong to the genus (28 isolates), one to (2 isolates), and one, remarkably, to (20 isolates). The largest cluster (17 isolates) grouped with the species, and the other five clusters were close to different recently defined species. Isolates close to were obtained from nodules of plants from four of the five sites sampled. We carried out an in-depth phylogenetic study with representatives of the seven clusters using sequences from housekeeping genes ( , , , , and ) and obtained consistent results. A phylogeny based on the sequence of the symbiotic gene identified four groups, three formed by isolates and one by the and isolates. Symbiotic behaviors of the representative strains were tested, and some congruence between symbiovars and symbiotic performance was observed. These data indicate a remarkable diversity of root nodule symbionts in northern Tunisia, including strains from the , , and families, in contrast with those of the rhizobial populations nodulating lupines in the Old World, including from other Mediterranean areas, which are nodulated mostly by strains. is a legume broadly distributed in the Mediterranean region and plays an important role in soil fertility and vegetation coverage by fixing nitrogen and solubilizing phosphate in semiarid areas. Direct sowing to extend the distribution of this indigenous legume can contribute to the prevention of soil erosion in pre-Saharan lands of Tunisia. However, rhizobial populations associated with are poorly understood. In this context, the diversity of endosymbionts of this legume was investigated. Most species are nodulated by strains. This work showed that about half of the isolates from northern Tunisian soils were in fact symbionts, but the other half were found unexpectedly to be bacteria within the genera and These unusual endosymbionts may have a great ecological relevance. Inoculation with the appropriate selected symbiotic bacterial partners will increase survival with consequent advantages for the environment in semiarid areas of Tunisia.

[Ab] Resumo:OBJECTIVE: To identify and characterize a novel aryloxyphenoxypropionate (AOPP) herbicide-hydrolyzing carboxylesterase from Aquamicrobium sp. FPB-1. RESULTS: A carboxylesterase gene, fpbH, was cloned from Aquamicrobium sp. FPB-1. The gene is 798 bp long and encodes a protein of 265 amino acids. FpbH is smaller than previously reported AOPP herbicide-hydrolyzing carboxylesterases and shares only 21-35% sequence identity with them. FpbH was expressed in Escherichia coli BL21(DE3) and the product was purified by Ni-NTA affinity chromatography. The purified FpbH hydrolyzed a wide range of AOPP herbicides with catalytic efficiency in the order: haloxyfop-P-methyl > diclofop-methyl > fenoxaprop-P-ethyl > quizalofop-P-ethyl > fluazifop-P-butyl > cyhalofop-butyl. The optimal temperature and pH for FpbH activity were 37 °C and 7, respectively. CONCLUSIONS: FpbH is a novel AOPP herbicide-hydrolyzing carboxylesterase; it is a good candidate for mechanistic study of AOPP herbicide-hydrolyzing carboxylesterases and for bioremediation of AOPP herbicide-contaminated environments.

[Ab] Resumo:Two bacterial strains, 2-2-12-1T and 2-2-12-2, were isolated from the estuary of the Jiulong River, south-east China. Cells were Gram-stain-negative, non-motile, short rods without flagella. Growth occurred at 25-45 °C, at pH 5.0-9.0 and with 0.5-2 % (w/v) NaCl. The bacteria were unable to reduce nitrate. The predominant fatty acids were C19 : 0 cyclo ω9c and C18 : 1ω7c. Phylogenetic analysis based on 16S rRNA gene sequences showed that both strains belong to the genus Nitratireductor, family Phyllobacteriaceae, class Alphaproteobacteria. Their closest neighbours were 'Nitratireductor lucknowense' DSM 24322 (96.3 and 96.5 % similarity, respectively) and Nitratireductor pacificus MCCC 1A01024T (96.2 and 96.3 % similarity, respectively). The DNA G+C contents of the two strains were 56.7 mol%. DNA-DNA hybridization between strain 2-2-12-1T and the two most closely related type strains revealed 57.3 and 52.3 % relatedness, respectively. Evidence from genotypic, chemotaxonomic and phenotypic data indicated that strains 2-2-12-1T and 2-2-12-2 represent a novel species of the genus Nitratireductor, for which the name Nitratireductor aestuarii sp. nov. is proposed. The type strain is 2-2-12-1T (=LMG 29090T=CGMCC 1.15320T).

[Ab] Resumo:A Gram-staining-negative, aerobic, non-motile, capsule-forming and rod-shaped bacterium, designated JH-7T, was isolated from sludge of a manganese mine. The 16S rRNA gene sequence of JH-7T showed highest similarities to those of Pseudaminobacter salicylatoxidans BN12T (97.4 %), Mesorhizobiumthiogangeticum SJTT (97.0 %) and Pseudaminobacter defluvii THI 051T (96.5 %). Phylogenetic trees clustered JH-7T together with P. salicylatoxidans BN12Tand P. defluvii THI 051T. The DNA-DNA hybridization values between JH-7T and P. salicylatoxidans DSM 6986T and between JH-7T and M. thiogangeticum DSM 17097T were 34.8 and 20.1 %, respectively. The major fatty acids of JH-7T (>10 %) were C18 : 1ω7c, C19 : 0cyclo ω8c and C16 : 0. The genomic DNA G+C content was 61.6 mol%. The polyamines of JH-7T were sym-homospermidine (83 %) and putrescine (17 %), and the respiratory quinone was ubiquinone-10. The major polar lipids were phosphatidylmonomethylethanolamine, diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine, two unidentified aminolipids and two unidentified lipids. Compared with the members of the genera Pseudaminobacter and Mesorhizobium, JH-7T showed some unique physiological and biochemical characters, such as being negative for H2S production, hydrolysis of Tween 40 and Tween 60, esterase lipase (C8) activity and assimilation of d-ribose and positive for acid production from d-galactose and assimilation of d-fructose. On the basis of the results of the polyphasic taxonomic analysis, JH-7T was considered to represent a novel species of the genus Pseudaminobacter, for which the name Pseudaminobacter manganicus sp. nov. is proposed. The type strain is JH-7T (=KCTC 52258T=CCTCC AB 2016107T).

[Ab] Resumo:Aminobacter sp. MSH1 immobilized in an alginate matrix in porous stones was tested in a pilot system as an alternative inoculation strategy to the use of free suspended cells for biological removal of micropollutant concentrations of 2,6-dichlorobenzamide (BAM) in drinking water treatment plants (DWTPs). BAM removal rates and MSH1 cell numbers were recorded during operation and assessed with specific BAM degradation rates obtained in lab conditions using either freshly grown cells or starved cells to explain reactor performance. Both reactors inoculated with either suspended or immobilized cells showed immediate BAM removal under the threshold of 0.1 µg/L, but the duration of sufficient BAM removal was 2-fold (44 days) longer for immobilized cells. The longer sufficient BAM removal in case of immobilized cells compared to suspended cells was mainly explained by a lower initial loss of MSH1 cells at operational start due to volume replacement and shear. Overall loss of activity in the reactors though was due to starvation, and final removal rates did not differ between reactors inoculated with immobilized and suspended cells. Management of assimilable organic carbon, in addition to cell immobilization, appears crucial for guaranteeing long-term BAM degradation activity of MSH1 in DWTP units.

[Ab] Resumo:A Gram-staining-negative, strictly aerobic bacterial strain, designated MA7-20T, was isolated from a marine alga, Porphyridium marinum, in Korea. Cells showing oxidase-positive and catalase-positive activities were motile rods with bipolar flagella. Growth of strain MA7-20T was observed at 15-45 °C (optimum, 30-37 °C), at pH 6.0-10.5 (optimum, pH 7.0-8.0) and in the presence of 0-7 % (w/v) NaCl (optimum, 2-3 %). Strain MA7-20T contained summed feature 8 (comprising C18 : 1ω7c/C18 : 1ω6c), 11-methyl C18 : 1ω7c and C18 : 0 as the major fatty acids and ubiquinone-10 as the sole isoprenoid quinone. The major polar lipids were phosphatidylcholine, phosphatidylglycerol, diphosphatidylglycerol, phosphatidylethanolamine and phosphatidyl-N-methylethanolamine. The G+C content of the genomic DNA was 61.5 mol%. Strain MA7-20T was most closely related to Hoeflea suaedae YC6898T, Oricola cellulosilytica CC-AMH-0T and Nitratireductor basaltis J3T with 96.0, 95.8 and 95.8 % 16S rRNA gene sequence similarities, respectively, but the strain formed a distinct phylogenetic lineage from them within the family Phyllobacteriaceae with a low bootstrap value. H. suaedae also formed a clearly distinct phylogenetic lineage from other members of the genus Hoeflea and closely related genera. On the basis of phenotypic, chemotaxonomic and molecular properties, strain MA7-20T represents a novel species of a new genus of the family Phyllobacteriaceae, for which the name Roseitalea porphyridii gen. nov., sp. nov. is proposed. The type strain is MA7-20T (=KACC 18807T=JCM 31538T). In addition, H. suaedae is also reclassified as Pseudohoeflea suaedae gen. nov., comb. nov. (type strain YC6898T=KACC 14911T=NBRC 107700T).

Strain NK8 was observed to grow optimally at pH 7.0, 30 °C and in the absence of NaCl in LB medium. The G + C content of the total DNA of strain NK8 was found to be 65.5 mol%. The 16S rRNA gene sequence of strain NK8 showed high similarity to that of Aquamicrobium aerolatum Sa14 (97.3%), followed by Aquamicrobium lusatiense S1 (96.7%) and Mesorhizobium sangali SCAU7 (96.6%). The DNA-DNA relatedness between strain NK8 and A. aerolatum Sa14 was 35.5 ± 0.9%. The major fatty acids of strain NK8 were determined to be C cyclo ω8c (45.6%), C ω7c (33.4%) and C (8.4%). The respiratory quinone was found to be ubiquinone Q-10. The major polyamine was found to be spermidine. The polar lipid profile include the major compounds phosphatidylcholine and diphosphatidylglycerol, and moderate amounts of phosphatidylethanolamine, phosphatidylmonomethylethanolamine, aminolipid and phospholipid. Based on the differential biochemical and physiological characteristics, the geno-, chemo- and phenotypic characteristics, strain NK8 is proposed to represent a novel species of the genus Aquamicrobium, Aquamicrobium soli sp. nov. The type strain is NK8 (=KCTC 52165 =CCTCC AB2016045 ).

[Ab] Resumo:This is the taxonomic study of a novel bacterial strain, designated GSS14T, isolated from a sediment sample of Yuncheng Salt Lake, China. Cells were Gram-negative, ovoid to rod-shaped and motile by means of flagella. The isolate could grow at 10-45 °C, at pH 6.5-11.0 and in the presence of 0-12 % (w/v) NaCl. The dominant fatty acids were summed feature 8 (consisting of C18 : 1ω7c and/or C18 : 1ω6c; 76.7 %) and the DNA G+C content was 61 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain GSS14T was affiliated with the genus Nitratireductor, and it was most closely related to Nitratireductor kimnyeongensis KY 101T (98.2 % 16S rRNA gene sequence similarity) and Nitratireductor aquibiodomus JCM 21793T (96.6 %). DNA-DNA hybridization between strains GSS14T and N. kimnyeongensis KY 101T revealed 52 % relatedness. Phenotypic, chemotaxonomic and phylogenetic data support assignment of this isolate to the genus Nitratireductor as a representative of a novel species. The name Nitratireductor lacus sp. nov. is proposed, with strain GSS14T (=KCTC 52186T=MCCC 1K02481) as the type strain.
