Plant growth promoting halobacteria associated to plant growth promoting halobacteria associated to Lippia palmeri (Verbenaceae) in the arid zone of northwestern Mexico
The production of oregano is of economic relevance in northwestern Mexico. However, to obtain high yields, producers resort to chemical fertilization, but its misuse increases salinity. Lippia palmeri Watts is a species of oregano that naturally grows in arid soils with poor organic matter, high salinity and temperature in the northwestern Mexico. In the context of sustainable agriculture, microorganisms activate soil fertility and increase plant productivity. Currently there is interest in proposing biofertilizers in the agriculture with high saline intrusion and temperatures for the cultivation of oregano. The Plant Growth Promoting Halobacteria (HPCP) have stood out by the beneficiary of the nutritious crops and mitigate the effect of the salinity. The goal of this work was to identify HPCP associated to the rhizosphere of L. palmeri, thermo and halotolerant; phosphate solubilizing activity, organic acid production, siderophores and nitrogen fixation were evaluated; the highest activity colonies were identified by the rRNA-16S gene and the effect on germination and root length was evaluated. Fifteen different colonies stood out when growing in NaCl (0.25, 0.50 and 0.75 M) at 35 and 45 °C, from which three bacteria were identified: Bacillus amyloliquefaciens, Bacillus subtilis and Bacillus licheniformis. The effect on root length was significant for B. amyloliquefaciens. Studies related to plant promotion should be involved in subsequent studies. This is the first report of Bacillus amyloliquefaciens as a nitrogen fixing bacteria associated with Lipia palmeri.

The production of oregano is of economic relevance in northwestern Mexico. However, to obtain high yields, producers resort to chemical fertilization, but its misuse increases salinity. Lippia palmeri Watts is a species of oregano that naturally grows in arid soils with poor organic matter, high salinity and temperature in the northwestern Mexico. In the context of sustainable agriculture, microorganisms activate soil fertility and increase plant productivity. Currently there is interest in proposing biofertilizers in the agriculture with high saline intrusion and temperatures for the cultivation of oregano. The Plant Growth Promoting Halobacteria (HPCP) have stood out by the beneficiary of the nutritious crops and mitigate the effect of the salinity. The goal of this work was to identify HPCP associated to the rhizosphere of L. palmeri, thermo and halotolerant; phosphate solubilizing activity, organic acid production, siderophores and nitrogen fixation were evaluated; the highest activity colonies were identified by the rRNA-16S gene and the effect on germination and root length was evaluated. Fifteen different colonies stood out when growing in NaCl (0.25, 0.50 and 0.75 M) at 35 and 45 °C, from which three bacteria were identified: Bacillus amyloliquefaciens, Bacillus subtilis and Bacillus licheniformis. The effect on root length was significant for B. amyloliquefaciens. Studies related to plant promotion should be involved in subsequent studies.

Sin embargo, los productores para obtener altos rendimientos recurren a la fertilización química, pero su mal uso, agudiza la salinidad. Lippia palmeri crece de manera natural en suelos áridos, pobres en materia orgánica, alta salinidad y temperatura en el noroeste de México. En el contexto de una agricultura sustentable, los microorganismos mantienen la fertilidad del suelo e incrementan la productividad de la planta. Actualmente existe interés en proponer biofertilizantes en la agricultura de alta intrusión salina y elevadas temperaturas para el cultivo de orégano. Las Halobacterias Promotoras del Crecimiento de Plantas (HPCP), se han destacado por beneficiar a los cultivos nutrimentalmente y mitigar el efecto de la salinidad. El objetivo del presente trabajo consistió en identificar termo- y halo-tolerantes HPCP asociadas a la rizosfera de L. palmeri; se evaluó la actividad solubilizadora de fosfatos, producción de ácidos orgánicos, sideróforos y fijación de nitrógeno; se identificaron mediante el gen ARNr-16S aquellas con alta actividad evaluándose su efecto en la germinación y longitud radicular. Quince diferentes colonias sobresalieron al crecer en NaCl (0.25, 0.50 y 0.75 M) a 35 y 45 °C, destacando tres bacterias identificadas: Bacillus amyloliquefaciens, Bacillus subtilis y Bacillus licheniformis. El efecto en la longitud radicular es significativo por la aplicación de B. amyloliquefaciens. Estudios relacionados con la promoción vegetal deben ser considerados en posteriores estudios. Este es el primer informe de B. amyloliquefaciens como una bacteria fijadora de nitrógeno asociada a L. palmeri.
