influential factors, such as gas, solution, solids, microorganism and heat. Oxygen is a fundamental element for aerobic microorganism activity and propagation, and it’s usually provided by the gas... with the livixiant and the heap. 5) The overall microorganism to adsorptive quantity ratio is a constant. The heap height is 20 m, the slope angle is 40°, and the upper and bottom widths are 32.3 m and 80......
and the sustainability of renewable biomass [10]. Bioremediation is targeted to reduce the pH, sodicity and salinity of bauxite residue, and microorganism plays a vital role in bioremediation. Microorganism... as nutrients for the production of citric, acetic and lactic acid by microorganism [12], which makes the alkalinity of bauxite residue decrease during remediation. Some microorganism produces inorganic acids......
capacity of the fluid at constant pressure; b is the chemotaxis constant; Wc is the maximum cell swimming speed (bWc is assumed to be constant); Dn is the microorganism diffusivity; kf is the thermal... microorganisms, Nn, which is the ratio of the convective microorganism transfer to the rate of diffusive microorganism transport. The local skin friction coefficients in the x and y directions are given......
that the relative abundances of Fe-oxidizers, S-oxidizers and other Herotrophic acidophiles were different at dissimilar sites, as well as microorganism community composition. Even if the geography... of Leptospirillum ferrooxidans except for clone GXDC-19 (Fig.2). There are eight OTUs associated with Leptospirillum ferrooxidans. Gamma-Proteobacteria was another dominant microorganism according......
and a possible new microorganism were dominant groups in the Chinese acid mine drainage. Moreover, the RFLP and 16S rRNA sequences analysis showed that the heterotrophic acidophilic microorganism... was detected in DWT and SLS. 16S rRNA sequences analysis also showed that a kind of microorganism possibly belonging to a new genus or species was extensively found in the mine districts and had......
drying, frozen preservation at -20 ℃ or -70 ℃ could obviously increase the storing time of the microorganism and improve the cell viability for long periods[10]. On the other hand, freeze drying... way for storing the special bioleaching microorganism in a long time. While storing in a short time, this method is not considered to be a good way due to causing serious cells death. 2) Freeze......
parameters towards metal contamination because dehydrogenase only occurs within living cells. Dehydrogenase activity can reflect the ability of microorganism taking part in redox reaction... activity is probably caused by the action of soil microorganism’s detoxification system. Fig.1(c) shows the total effect of Cr(Ⅵ) on polyphenol oxidase activity. All the tested Cr(Ⅵ) concentrations......
inocula of Pseudomonas aeruginosa ZH able to assist the growth of sulfur-oxidizing microorganism by consuming microbial metabolites and oxidizing S0 produced acid which is benefit for the sulfur-oxidizing microorganism growth and Acidithiobacillus thiooxidans DMC able to oxidize sulphur and sulfide. 2 Experimental 2.1 Contaminated sediment The sediment for the present study was collected from......
and for removal of chromium-containing wastewater by microorganism Achromobacter sp. CH-1 were put forward, and then the correlated researches have been done. During the process of bacterial cultivation..., phosphatide is considered as the sign of the microorganism biomass in the sea and the bayou sediment. Electronic impedance methods based on the electrochemistry technology can be used to confirm the growth......
r/min in a rotary shaker for 3-4 d. The cultures were plated onto the solid media with Hg2+ from 10 mg/L to 65 mg/L to select the highest mercury-resistant isolate. The microorganism resistance... of strain D2 Microorganisms might develop various mechanisms to resist antibiotics and tolerate metals under environmental conditions of heavy metal. The presence of such mercury-resistant microorganism......
