Monitoring of microbial population of the páramo soil of the charge zone of lake Mapahuiña in Chimborazo-Ecuador

Abstract:

The present investigation analyzed the presence of microorganisms in soils of the recharge zone of the Lake Mapahuiña, Ecuador. The location has a large microbial diversity which is characterized by a páramo ecosystem presenting acidic soil types, which coincides with other paramunos volcanic soils analyzed in the region. The general microbial analysis revealed a considerable amount of microorganisms in each region of study, with no significant correlation found regarding the physical and chemical characteristics measured. For microalgae, the banks of the Lake Mapahuiña had the highest concentration (5, 5 x 105 cells/mm3) in contrast to the Pine forest area (1, 7 x 105 cells/mm3). Microalgae growth showed significant differences with respect to pH, relative soil humidity, and vegetation type with soil temperature relatively homogeneous. Our study is the first investigation of the area and presents the foundation for unearthing microbial strains of biotechnological interest.
