The solubility of (NH 4) 2SO 4 in water at temperatures of 0 to 30вЊ is approximately 530В gВ l в€’1 or 4В M. For these reasons, ammonium sulphate (NH 4) 2SO 4 is the most frequently applied precipitant for protein salting-out. The salt must also be highly soluble in aqueous solutions to achieve the concentrations required, and should not have a large heat of solution ( Section 5.4.3) to avoid temperature increases that might denature the product or affect its solubility. Protein precipitation at an industrial scale requires large amounts of salt therefore, it is important that the salt used be inexpensive. (11.38) citrate > phosphate > sulphate > acetate > chloride > nitrate > thiocyanateД«ecause polyvalent cations such as calcium and magnesium depress the value of K S, ammonium, potassium, and sodium salts are used widely. It has been reported that salinity stress reduces the chlorophyll content as well as promotes the accumulation of proline, malondialdehyde, and hydrogen peroxide in roots and leaves of mung bean plants ( Zahran, 1991). It also decreases the activity of several enzymes such as nitrogenase and phosphatase in legumes and negatively affects the early growth and development of legume seedlings ( Farooq et al., 2017 Saghafi et al., 2018). The high concentration of salt affects bacterium ( Rhizobium)вЂ“legume symbiotic nitrogen-fixation potential in many legumes such as soybean, chickpea, pea, faba beans, mung beans, etc. It has been reported that under saline conditions there is a considerable reduction in K + and P availability to plant tissues, which results in low K +/Na + ratio and hinders the development of sustainable agriculture. Apart from increasing ethylene and its direct precursor ACC levels, soil salinity also induces ion toxicity, osmotic stress, oxidative stress, and nutritional imbalance in plants. High salt concentration is also a severe problem affecting the productivity and yield of leguminous plants in arid and semiarid regions. 239000005060 rubber Substances 0.Shikha Gupta, Sangeeta Pandey, in Abiotic Stress and Legumes, 2021 1.3.2.2 Salinity.229920001971 elastomer Polymers 0.000 claims abstract description 30.238000005187 foaming Methods 0.000 claims abstract description 41.238000005516 engineering process Methods 0.000 title abstract description 7.238000004073 vulcanization Methods 0.000 title claims abstract description 27.
