Phosphorus Recycling, Biocontrol, and Growth Promotion Capabilities of Soil Bacterial Isolates from Mexican Oak Forests: An Alternative to Reduce the Use of Agrochemicals in Maize Cultivation

Six bacteria (Bacillus velezensis 13, Bacillus subtillis 42, Pseudomonas fluorescens E221, Poae EE12, Rahnella sp. EM1, and Serratia EM2) isolated from the soil litter of Mexican oak forests were characterized by identifying their ability to acquire phosphorus different sources, analyzed for biocontrol capabilities against two phytopathogenic fungi, finally tested stimulate germination maize seeds promotion seedling growth. The greatest capacity mycelial growth fungi Botrytis cinerea Fusarium oxysporum was found in B. 13 42. P. poae EE12 E221 significantly promoted length primary root Zea mays. EM1 EM2 could produce indole compounds related auxin synthesis increased fresh weight seedlings. Together, these isolates represent an alternative reduce use agrochemicals cultivation. In general, microorganisms a source genetic resources sustainable management conservation soils agricultural use.
