Lipopeptides are known as promising microbial surfactants and have been successfully used in enhancing oil recovery extreme environmental conditions. A biosurfactant-producing strain, Bacillus atrophaeus 5-2a, was recently isolated from an oil-contaminated soil the Ansai oilfield, Northwest China. In this study, we evaluated crude removal efficiency of lipopeptide biosurfactants produced by B. 5-2a their feasibility for use enhanced recovery.The production tested culture media containing...
Abstract Yuba is a traditional soy product made from soymilk. However, producing nutritious yuba with high quality and yield remains challenge. This study aimed to optimize the mechanical nutritional properties of by adding whey protein isolate (WPI). The impact ultrasound powers (0-800 W) on physicochemical WPI-soymilk dispersions their product-yuba was studied. group at 400 W had highest surface hydrophobicity (3917.25 ± 10.54) free sulfhydryl content (52.31 0.39 μmol/g proein). Compared...
Cadmium (Cd) and arsenic (As) contamination of soil has been a public concern due to their potential accumulation risk through the food chain. This study was conducted investigate performance ferrous sulfate (FeSO4) ferric oxide (Fe2O3) nanoparticle (Nano-Fe) stabilize concentrations Cd As in paddy soil. Both Fe treatments led low extractable contents specifically sorbed contents, increased (p < 0.05) Shannon index decreased Simpson diversity indices compared with control. Nano-Fe relative...
Servo-proportional valves are gradually being introduced into aircraft electro-hydraulic systems as performance improves. Reducing the flow force of is beneficial in improving rapidity and stability valve operation. Meanwhile, maintaining linearity structural design can prevent reduction margin load system control. Therefore, a non-throttling port spool guide bevel designed to reduce based on relationship between jet angle force. A step structure maintain alleviate reversal problem. To...
Microbial-induced calcium carbonate precipitation is an efficient and environmentally friendly soil stabilization technology. To explore the mineralization performance of precipitation, this study selects three factors, including type cementing solution (TCS), concentration (CSC), ratio bacteria to (B/C ratio), investigate their effects on microbial mineralization. This reveals influence each factor amount rate analyzes changes in characteristics crystals, such as crystal diameter. The...
Microbial enhanced oil recovery has played a major role in enhancing crude from depleted reservoirs to solve stagnant petroleum production.
Cam-lobe radial-piston hydraulic motors are widely used in large heavy-duty machinery as direct-drive components of systems. Due to their extremely high output torque and power density, the wet brake equipped with necessary achieve ultra-high braking a compact space. How optimize structure friction pairs reduce temperature rise non-braking state is persistent challenge. For that, this study proposed an optimization approach for low-temperature motor. In approach, process could be divided...
Wheat-bran (Triticum aestivum L.) antifreeze protein (TaAFP) was purified 323-fold to electrophoretic homogeneity with an overall yield of 1.64% from wheat-bran by a specific three-step procedure. The procedure quicker, cheaper, and more effective than the five-step we used earlier. First, TaAFP concentrated phosphate buffer, on basis its strong hydrophilicity that validated thermal gravimetric analyses surface hydrophobicity analysis. Second, trapped in ice crystals for ice-binding...
