Microcystins (MCs) are the most common and toxic cyanotoxins that hazardous to human health ecosystems. Microcystinase is enzyme in charge of initial step biodegradation MCs. The characterization, application conditions, detoxification mechanisms microcystinase from an indigenous bacterium Sphingopyxis sp. YF1 towards MC-LR were investigated current study. gene strain was similar Sphingomonas USTB-05 contained a CAAX-family conversed abortive Infection (ABI) domain. successful obtained...
Acidithiobacillus ferrivorans is an acidophile that often occurs in low temperature acid mine drainage, e.g., located at high altitude. Being able to inhabit the extreme environment, bacterium must possess strategies copy with survival stress. Nonetheless, information on demand. Here, genomic and transcriptomic assays were performed illuminate adaptation mechanisms of A. strain YL15, alpine drainage environment Yulong copper southwest China. Genomic analysis revealed has a gene repertoire...
Low-temperature biohydrometallurgy is implicated in metal recovery alpine mining areas, but bioleaching using microbial consortia at temperatures <10°C was scarcely discussed. To this end, a mixed culture used for chalcopyrite 6°C. The resulted higher copper leaching rate than the pure of Acidithiobacillus ferrivorans strain YL15. High-throughput sequencing technology showed that spp. and Sulfobacillus were culture’s major lineages. Cyclic voltammograms, potentiodynamic polarization...
Our knowledge on the dissolution and passivation mechanisms of chalcopyrite during bioleaching at low temperature has been limited to date. In this study, an Acidithiobacillus ferrivorans strain with high tolerance heavy metals UV radiation was used for bioleaching. At 6 °C, no apparent precipitate detected mineral surface after using a scanning electron microscope (SEM). X-ray diffraction (XRD) revealed that ore residue contained only quartz. photoelectron spectroscopy (XPS) analysis...
Sphingopyxis sp. YF1 has proven to be efficient in biodegrading microcystin (MC)-leucine (L) and arginine (R) (MC-LR); however, the optimal environmental factors biodegrade toxin have not been investigated. In this study, characteristics of strain against MC-LR were assessed under diverse factors, including temperature (20, 30 or 40 °C), pH (5, 7 9) concentration (1, 3 5 µg/mL). Data obtained from single-factor experiment indicated that biodegradation by was temperature-, pH-...
Two novel acidothermophilic archaea, strains Ric-A T and Ric-F, were isolated from muddy water samples of a sulfuric hot spring located in Tengchong County, Yunnan Province, PR China. The aerobic facultatively chemolithoautotrophic. Both could oxidize S 0 K 2 4 O 6 for autotrophic growth, use organic materials heterotrophic growth. Growth was observed at 55–75 °C pH 1.5–6.5. metal sulfide ores, showing their potential bioleaching. DNA G+C contents Ric-F 41.8 41.6 mol%, respectively. Analysis...
To explore the distribution disciplinarian of alginate on chalcopyrite concentrate surface during bioleaching. The evolution Sulfobacillus thermosulfidooxidans secreting bioleaching was investigated through gas chromatography coupled with mass spectrometry (GC‐MS) and confocal laser scanning microscope (CLSM), critical synthetic genes (algA, algC, algD) were analysed by real‐time polymerase chain reaction (RT‐PCR). GC‐MS analysis results indicated that there a little amount formed mineral at...
