We developed a rapid method of total phosphorus (TP) determination in fresh water by optimizing the volumes and concentrations oxidant (potassium persulfate), reductant (ascorbic acid), colorant (molybdate + antimony potassium tartrate).Instead UV spectrophotometer, as used national standard (GB 11893-89), we iMark Microplate Absorbance Reader to measure absorbance.The principle TP was identical that sample digested under neutral condition oxidized orthophosphate colored absorbance.In...
To investigate the plasma membrane damage of chlorine dioxide (ClO(2)) to Candida albicans ATCC10231 at or below minimal fungicidal concentration (MFC).ClO(2) MFC was adopted treat cell suspensions C. ATCC10231. Using transmission electron microscopy, no visible physiological alteration shape and occurred. Potassium (K(+)) leakages were significant; likewise, it showed time- dose-dependent increases. However, adenosine triphosphate (ATP) very slight. Research shows that when 99% cells...
In the biological nitrogen cycle, nitrite oxidation is performed by bacteria, of which Nitrospira widespread and diverse. Communities were collected at 25-1500 m depths in South China Sea. Phylogenetic diversity, community composition, environmental factors investigated using high-throughput sequencing targeting nxrB gene statistical analyses. The composition varied spatially depth. Among 24 OTUs with relatively high abundance, 70% unclassified not affiliated known genus, suggesting a...
The oxidation of nitrite to nitrate as the second step nitrification is vital for global nitrogen cycle, and genus Nitrospira most widespread nitrite-oxidizing bacteria (NOB) in diverse natural ecosystems. However, our understanding distribution their response dynamic environmental parameters still limited subterranean estuary (STE), a special environment mixed zone between land sea. In this study, communities were collected within 5–10 cm depth intervals sediments with physiochemical...
There has been a trend toward the use of microorganisms as biomaterial for removing dyes and metals from wastewater. However, native microorganism cells have low mechanical stability, which limit their further application in industries. In this study, chlorine dioxide (ClO2), high-efficiency, low-toxicity, environmentally benign disinfectant, was used surface modification to enhance stability metal ion adsorption cell. ClO2 can either modify cell walls improve capacity or membranes...
Abstract Although multiple microorganisms can remove ammonium and nitrate simultaneously, their metabolic mechanisms are not well understood. Strain R-1, isolated from the activated sludge of a sewage treatment plant, was identified as Paracoccus denitrificans , found to efficiently under anaerobic aerobic conditions. The maximal NH 4 + removal rate (RR = 9.94 mg·L − 1 ·h ) significantly higher conditions than 2.91 ). Analysis nitrogen balance isotope tracers indicated that consumed through...
Leaf mustard ( Brassica juncea L. Czern & Coss), an important vegetable crop, experiences pronounced adversity due to seasonal drought stress, particularly at the seed germination stage. Although there is partial comprehension of drought-responsive genes, role long non-coding RNAs (lncRNAs) in adjusting mustard’s stress response largely unexplored. In this study, we showed that drought-tolerant cultivar ‘Weiliang’ manifested a markedly lower base water potential (−1.073 MPa vs −0.437...

Abstract The triple junction area, bordered by the Longmenshan, Xianshuihe, and Anninghe faults, is located at southeastern corner of Songpan–Ganzi block, northern Tibet. In this a series strong earthquakes occurred, including 2008 Mw 7.9 Wenchuan, 2013 6.6 Lushan, 2014 5.9 Kangding, 2022 5.8 Luding. addition, multiple hot springs with different temperatures are distributed along faults in same area. This study tries to figure out: (1) necessity catalog replenishment based on statistical...
