Lasallian professor participates on research into the impact of glyphosate on microorganisms
Rosalina González, professor of Environmental and Sanitary Engineering Program at Universidad de La Salle is currently a member of the International Lasallian Research Center where faculty from different lasallian universities in the world, meet to discuss common issues and have a global perspective.
“Thanks to this group I learned about the research of Dr. Jerry Kavouras, director of the Applied Biology and Environmental Microbiology Program at Lewis University, to whom I commented on my idea of analyzing the impact of glyphosate, not from the chemical side, but from an environmental biomonitoring, so his inquiries and research method could serve this purpose” explains Dr. Rosalina González.
With this goal in mind, González conducted a scientific research internship at Lewis University, where she formulated a project to monitoring quickly and economically the effect of glyphosate in soils by checking long-term microbial (biological) activity.
“The research method of Dr. Jerry Kavouras is not expensive and easy to use. Echo dishes are used for introducing the sample. In this case we take water and soil samples from three different places, one from a farm where they have used glyphosate for 15 years, another from an industrial zone and the last one from a nature reserve”, says the Professor.
Samples with and without glyphosate were analyzed in a five-day monitoring to assess how the behavior of the myco-organism community is.
"In conducting this study and analyze the behavior of the soil microbial community after five days, it was found that in all samples there was activity and as time progressed, further adaptation of microorganisms was observed on the ground; In some cases, at five days they had a similar behavior to that before applying the agrochemical. So you can analyze these have adaptability to applied doses”, explains González.
These analyzes continue in studies and more research is planned on Colombian soils and thus be able to determine remediation methods for ecosystems impacted with this highly controversial substance today.
