) chemolithoautotroph, metabolizing ferrous iron and pyrite. The optimal growth conditions for the strain are 40 ℃ and pH 1.6. A phylogenetic analysis based on 16S rRNA sequences shows that the isolate is clustered...% of iron are extracted from chalcopyrite and pyrite, respectively. Key words: Leptospirillum ferriphilum; bioleaching; isolation; characterization; phylogenetic analysis  ......
and temperature optima of 3.5 and 40 ℃, respectively. Spectroscopic experiments show that strain PJH can synthesize polyhydroxybutyrate (PHB). A phylogenetic analysis based on 16S rRNA sequences shows....; phylogenetic analysis; bioleaching; chalcopyrite  ......
populations thrived in Lau Basin hydrothermal vents that were previously not detected by either molecular retrieval or strain purification techniques. Key words: hydrothermal vents; phylogenetic analysis.... Different banding patterns were noted and analyzed. 2.6 Phylogenetic analysis By comparing the size and number of digested fragments, clones with unique RFLP patterns were picked out and sequenced......
is extracted from chalcopyrite by using strain ZW-1 as inocula. Key words: moderately thermophilic acidophilic bacterium; biochemical and physiological characteristics; phylogenetic analysis... and phylogenetic analysis of 16S rRNA DNA was extracted from the 25 mL inoculated vessels by centrifuging at 12 000 r/min for 10 min to pellet microorganisms. Then the pallet was washed with TE (pH 8.0......
; 16SrDNA; 18SrDNA and ITS; phylogenetic analysis 竹简是中国在晋以前档案的主要载体,对我国传统文明的传播起了至关重要的作用.湖南长沙简牍博物馆收藏了一批走马楼出土的三国时期吴国竹简,具有极为珍贵的史料价值.在出土后保存过程中,该批竹简爆发了一种竹简蚀斑病,竹简损害严重,白斑中的竹简竹体变为半透明膜状物质.胡东波等[1]从走马楼出土的带菌竹简浸泡液中分离出未知的M...Aspergillus的关系密切,由此将霉菌F-1归为曲霉属的1个种. 图1 基于分离细菌16SrDNA序列构建的系统发育树 Fig.1 Phylogenetic analysis based on the 16SrDNA sequences of the isolated strains 表3 霉菌F-1 18SrDNA及ITS序列比对结果......
, however, can not grow with NaS2O3 and peptone. The oxidation of Fe2+, sulfur and bioleaching marmatite with this strain was studied. A phylogenetic tree was constructed by comparing with the published 16SrDNA sequences of the relative bacteria species. In the phylogenetic tree, the TK strain is in a new branch which has the closest relative to the Acidithiobacillus ferrooxidans strain D2 with 98.67......
