I think cyanobacteria are best microorganisms for desalination of soils. Please check these useful PDF attachments.

Interesting question, we shall be happy to know about salt eating microbes which should have capacity to change salts into water and harmless gases like CO2 and ethane and further help in bio-remediation.

Role of Arbuscular Mycorrhiza in Amelioration of Salinity by  R. Hajibolan  

Abstract: Soil salinity is world wide problem because it negatively affect plant productivity and yield of plants particularly in arid and semi-arid regions of the world. Excessive salts decline soil water availability for plants, inhibit plants metabolism and nutrients uptake and is also responsible for osmotic imbalance. All of these changes contribute to stunted growth and less productivity of plants. Exploitation of soil microorganisms for utilizing salt affected soils is of considerable interest to plant and soil scientists. Arbuscular mycorrhizal fungi (AMF) are ubiquitous soil microorganisms inhabiting the rhizosphere and establish a symbiotic relationship with the roots of many plants. Arbuscular mycorrhizal fungi are from integral components of all natural ecosystems and are known to occur in saline soils. Symbiotic association of a plant with AMF results in higher ability for taking up the immobile nutrients in nutrient-poor soils as well as improvement of tolerance to salinity. The possible mechanisms for alleviation of salinity stress by AMF include: (1) improvement of plant nutrient uptake, particularly P, (2) elevation of K:Na ratio, (3) providing higher accumulation of osmosolutes, and (4) maintaining higher antioxidant enzymatic activities. In addition, some aquaporin genes are up-regulated in mycorrhizal plants, causing significant increase in water absorption capacity of salt-affected plants. In contrast, expression of proline biosynthetic enzymes and LEA genes as stress indicators are maintained in mycorrhizal salt stressed plants suggesting that mycorrhizal plants are less susceptible to salinity because of salinity-avoidance mechanisms.Role of Arbuscular Mycorrhiza in Amelioration of Salinity ...

The Role of Rhizobacteria in Salinity Effects on BiochemicalConstituents of the Halophyte Sesuvium portulacastrum1 , ISSN 10214437, Russian Journal of Plant Physiology, 2012, Vol. 59, No. 1, pp. 115–119. © Pleiades Publishing, Ltd., 2012.

Abstract—An experiment was conducted to understand the role of rhizospheric microorganisms in salinity effects on growth, antioxidants, pigments, and ion concentrations in the halophyte Sesuvium portulacastrum L. The plants grown in nonsterilized soil exhibited the enhanced growth rate, suppressed antioxidant enzymes, increased contents of chlorophylls and carotenoids, the greater accumulation of sodium and the reduction in the potassium ion concentration, as compared with the plants grown in microbefree soil. The dominantmicrobes identified from the rhizophere soil of nonsterilized plant groups included Bacillus cereus, Aeromo nas hydrophila, Pseudomonas aeruginosa, Corynebacterium xerosis, and Escherichia coli. The work emphasizes the importance of the rhizobacteria that colonize the root at the interface with soil in preventing the delete rious effects caused by salinity through accumulation of sodium and pigments and reduction of antioxidants and potassium.

Interesting responses. Isolation characterization and their evaluation of salt tolerant microbes are major issues to be exercised in saline soil for their effective remedies of saline soil.

Microbial amelioration of crop salinity stress by Ian C. Dodd Francisco Pérez-Alfocea published in  J Exp Bot (2012) 63 (9): 3415-3428.

Abstract

The use of soil and irrigation water with a high content of soluble salts is a major limiting factor for crop productivity in the semi-arid areas of the world. While important physiological insights about the mechanisms of salt tolerance in plants have been gained, the transfer of such knowledge into crop improvement has been limited. The identification and exploitation of soil microorganisms (especially rhizosphere bacteria and mycorrhizal fungi) that interact with plants by alleviating stress opens new alternatives for a pyramiding strategy against salinity, as well as new approaches to discover new mechanisms involved in stress tolerance. Although these mechanisms are not always well understood, beneficial physiological effects include improved nutrient and water uptake, growth promotion, and alteration of plant hormonal status and metabolism. This review aims to evaluate the beneficial effects of soil biota on the plant response to saline stress, with special reference to phytohormonal signalling mechanisms that interact with key physiological processes to improve plant tolerance to the osmotic and toxic components of salinity. Improved plant nutrition is a quite general beneficial effect and may contribute to the maintenance of homeostasis of toxic ions under saline stress. Furthermore, alteration of crop hormonal status to decrease evolution of the growth-retarding and senescence-inducing hormone ethylene (or its precursor 1-aminocyclopropane-1-carboxylic acid), or to maintain source–sink relations, photosynthesis, and biomass production and allocation (by altering indole-3-acetic acid and cytokinin biosynthesis) seem to be promising target processes for soil biota-improved crop salt tolerance.
