Soil degradation can be originated by salinity due to mishandling of agricultural activities which result in negative effects for the plant’s development and, consequently, crop yield. Because of this, different alternatives have been implemented to mitigate these effects, one of the most studied of these techniques recently have been the use of “Plant Growth Promoting Bacteria” (PGPB) which stimulate plant growth under limited conditions. PGPB have a positive effect by increasing nutrient availability and protecting the plant from a variety of different pathogens that might affect its development. The Streptomyces genera are one of the bacteria groups that inhabit the plant’s rhizosphere, present bioremediation capabilities, and have growth promoting activity; due to most of them having the ease of colonizing the rhizosphere by means of chemotaxis, synthesis of secondary metabolites and the capability of survive in different environments. Some Streptomyces strains which have been isolated from limiting environments, can also possess these PGP characteristics, due to them been able to adapt to different agroecological situations and can be implemented as a positive complement for the plant’s development. Similarly, halotolerant strains have been reported to have the capability of promoting plant growth in salinity-troubled soils by augmenting growth significantly in different parts of the plant. From this starting point, it is desired to demonstrate PGP capacity in native halotolerant Streptomyces strains, isolated from minerals found in mining zones, in salinity conditions by evaluating the plant´s sprout and root length as well as its dry and fresh weight.
