WebbAs biological membranes are permeable to water, any microorganism living at high salt concentrations has to maintain its intracellular environment at least isosmotic with the salt concentration in its environment and even hyperosmotic when a turgor pressure has to be maintained (Brown 1976, 1990; Csonka 1989; Grant 2004; Vreeland 1987). WebbIndustrialization causes the generation of phenolic pollutants in the environment. The ability of laccases to oxidize phenolic compounds and reduce molecular oxygen to water has led to intensive studies on these enzymes. Although salt-tolerant fungi are potential sources of enzymes for industrial applications, they have been inadequately explored for …

Webb21 feb. 2024 · When the salt concentration is too high, it means that the soil’s osmotic potential is essentially negative. Plants suffer from osmotic stress when they fail to take up water, even when it is present in the soil. Basically, the process is similar to drought stress due to a lack of moisture in the ground. As a result, vegetation dies.
