Introduction
I'm a PhD in Environmental Science and Technology (UAB, Spain). I was working on understanding the dynamics and bacterial community composition in autotrophic biological nitrogen removal from urban wastewater. Now, I'm back at the University of Concepción (Chile) as Laboratory Chief and working on different projects studying bacterial communities diversity in several environmental systems. I'm a beginner in the use of bioinformatics tools in the omic era, but I learn quickly.

Article
Biases on molecular techniques used to study microbial communities in the anammox process are not always considered. This work aimed to evaluate different molecular approaches to study bacterial communities in an anammox reactor treating real urban wastewater at mainstream conditions. 16 S rRNA amplicon sequencing with different primer sets, metage...
Article
In Chile, species of true morels have traditionally been identified on the basis of few morphological characteristics, but overall the genus Morchella has been poorly investigated and no studies combining morphological with molecular data exist. Here, Morchella collections from native forests of Nothofagus in Chilean Patagonia were characterized by...

Nitrogen, P and K are essential macronutrients that are not readily available to plants. Rhizobacteria are able to convert these unavailable forms for subsequent uptake by the plant, diverse species have been characterized as N2 fixers, P solubilizers and capable to solubilize mineral K from unavailable forms. The objective of this study was to sel...
Article
Alfalfa (Medicago sativa L. subsp. sativa) has emerged as an alternative crop for Mediterranean dryland areas in Chile. These soils show deficient nutritional levels affecting legume nodulation and N fixation through symbiosis with Ensifer meliloti. The objective of this work was to select plant growth promoting rhizobacteria (PGPR) associated with...
Article
The walnut blight disease, caused by the bacterium Xanthomonas arboricola pv. juglandis (Xaj) severely affects walnut production in the Biobio Region in Chile. The disease control is based on the excessive use of cupric bactericides (12 to 14 spray applications during the growing season), which can generate resistance by the bacteria. This research...

Lentil is cultivated in Chilean Mediterranean drylands, in areas with soils that are nutrient depleted and eroded. Inoculation of lentil with rhizobia in co-inoculation with growth promoting rhizobacteria would allow higher biomass and an opportunity for early nodulation and increased nitrogen fixation. The objective of this research was to select...

Legumes in the genus Adesmia are wild species with forage and medicinal potential. Their nitrogen fixation efficiency depends on their association with soil bacteria known as rhizobia. The aim of this work was to assess the diversity and symbiotic effectiveness of root nodule bacteria from Adesmia boronioides, Adesmia emarginata and Adesmia tenella...

Aegorhinus superciliosus is an important pest on blueberry (Vaccinium corymbosum L.) and other fruit trees. The use of entomopathogenic fungi as Metarhizium spp. has been evaluated for the control of this insect, but variability has been observed among different strains. The aim of this study was to characterize six promising strains of Metarhizium...
Article
Magnesium is an element essential for life and is found ubiquitously in all organisms. The different cations play important roles as enzymatic co-factors, as signaling molecules, and in stabilizing cellular components. It is not surprising that magnesium salts in microbiological experiments are typically associated with positive effects. In this st...
