Optical characterization of salt-induced swelling behavior of poly(N -isopropylacrylamide) terpolymer hydrogel layers

tailieu.vn

At very low salt concentrations M) the swelling of the layers did not change significantly, whereas a large increase in swelling was observed upon. A further increase in the salt concentration led to a reduction in the solvent quality of the salt solution and due to this PNIPAAm layers started to collapse at high salt concentrations (1 M). MABP [20] and propyl- 3-(4-benzoylphenoxy) thioacetate (BPSAc) [22] were synthesized as described in the literature. Synthesis of PNIPAAm terpolymer.

Physiological and biochemical responses to salt stress in the mangrove

tailieu.vn

We were unable to find such major differences in salt concentration between xylem sap and medium as those reported by Scholander and co-workers (Scholander et al., 1962;. 3, salt concentrations in sap from different plant parts were always lower than in the medium. These enzymes differed in their response from the seven enzymes from the leaves of the secreter mangrove A. marina, studied by Ashihara et al. All seven enzymes were strongly inhibited at 500 mM NaCl..

Revegetation on abandoned salt ponds relieves the seasonal fluctuation of soil microbiomes

tailieu.vn

Of the restoration strategies, phytoremediation that utilizes salt-tolerant plants and soil microorganisms to reduce the salt concentrations is believed to be environmentally-friendly. However, little is known about the change of bacterial community during salt pond restoration in the context of phytoremediation.. In the present study, we used 16S metagenomics to compare seasonal changes of bacterial communities between the revegetated and barren salterns at Sicao, Taiwan..

Effects of salinity and shaking condition on the growth and virulence of vibrio parahaemolyticus

tailieu.vn

In this work, we investigated different salt concentrations for BHI only and it was observed that the growth of V.. parahaemolyticus was similar between 2.5 and 3.0% NaCl condition while significantly different to 2.0% NaCl. At 2.0% NaCl, V.. parahaemolyticus also expressed significantly high activity of gelatinase than in higher salt concentrations (p<0.05). Therefore, it can be suggested that the three enzymes are kind of important for the growth and survival of V.

Two quinoa genotypes and four NaCl salt concentrations and 300 mM) were laid out in factorial experiment in RCBD with three replications. Salinity stress was induced by irrigation with nutrient solution containing NaCl with corresponding concentrations to quinoa plants grown in sands for two weeks during flowering initiation (35 days after sowing).

Handbook of Plant Nutrition - chapter 20

Title: The effect of fermentation temperatures and salt concentrations on the quality of pickled purple onion. Ở nước ta, các sản phẩm rau muối chua thường được chế biến theo phương pháp lên men tự nhiên nên chất lượng sản phẩm không ổn định và thời gian bảo quản ngắn. Nguyên nhân là do quá trình lên men chịu ảnh hưởng của nhiều yếu tố như: chế độ tiền xử lý nguyên liệu, nồng độ muối, nhiệt độ lên men, nguồn giống.

RNA : DNA and RNA : RNA hybrids require slightly lower salt concentrations of 0.18 to 1.0 M to increase hybridization by twofold.. Incorrect pH may impair hybrid formation because the charge of the nucleic acid phosphate backbone is pH dependent. The pH is typically adjusted to 7.0 or from 7.2 to 7.4 for hybridization experiments. to 0.1% Tween-20, 0.1% N-lauroylsarcosine, or Nonidet P-40 have been used in hybridization buffers.

With some adaptations, the proteins of these organisms can remain active in high salt concentrations (Karan et al., 2012). Moreover, halophilic archaea use simple carbon sources and high salt concentrations favored for industrial simple production systems in which enclosed sterile conditions omitted (Hezayen et al., 2001). Currently, halophilic microorganisms, especially halo-archaea, have received a lot of attention for lipase production (Delgado-García et al., 2012.

Productivity of cowpea as affected by salt stress in presence of endomycorrhizae and pseudomonas fluorescens

tailieu.vn

Previous studies have documented that proline (Taffouo et al., 2010) and sugar levels (Praxedes et al., 2011), are increased in salt stressed legumes and play a key role as osmolytes to maintain the water relation in plants. It also functions as a hydroxyl radical scavenger (Cha-um et al., 2013).. Our results demonstrated a decrease in pro- tein concentrations in plants treated with 3000 ppm NaCl solution, and increases, in protein concentrations in plants trea- ted with 6000 ppm NaCl solution.

Salt susceptibility index and salt tolerance index of the wheat genotypes tested were studied on the two concentrations of NaCl (100 and 200 mM/L). Results showed that the cross (Line-A · Gemmeiza-7) gave better re- sponse to salt susceptibility index (1.85), while the control par- ent (Line-A) gave lowest response to salt susceptibility index (0.13) as compared to its derived crosses.
