Seminar: Using physical processes in biological systems

Mr. Manuel Sandoval in his seminarThe activity counted with two exhibitions about research where are applied physical process in biological systems.

On Thursday 6 September, a seminar was presented by the Division of Optical Instrumentation and Sensing Technologies of our Center, which featured talks about “Biophotonics in the Microbiological Research of the Atacama Desert” and “bioleaching of sulphide ores and e-waste “.

Armando Azúa-Bustos, academic from the Department of Molecular Genetics and Microbiology at the Catholic University of Chile, visited CEFOP within the framework of his  partnership with Dra. María José Gallardo and Dr. Juan Pablo Staforrelli. This partnership aims to carry out experimental research to use in biophotonic and  obtain individual bacteria and cyanobacteria, that is, by isolating bacteria optical tweezers.

On that occasion, researcher from PUC, spoke in detail about his research in the area of the Atacama Desert, specifically about existence and characterization of microorganisms and their tolerance to extreme conditions and UV radiation.He also elaborate on into development research around the microbiology of caverns, where photosynthesis is examined inside of caverns, and which is associated with the NASA program on detection of caves on Mars, through thermography infrared and thermal differential phenomenon of air contained within the cavern.

Manuel Sandoval, student from Environmental Microbiology Laboratory at University of Lagos, had the second presentation. Student was directed by Dr. Alex González, who discussed apps of physical processes in biological systems, especially in the bioleaching of minerals sulfur. The research was under the supervision of Dr. María José Gallardo and Dr. Juan Pablo Staforelli.

In Bioleaching are used bacterias and their chemical reaction for dissolution of heavy minerals. That means that bacteria feeds with the mineral. The process has been observed by infrared spectroscopy in the Transmission Laboratory from Optoelectronics Division, where it is possible detect changes in temperature for the process.

Sandoval took the opportunity to speak about experimental research that he has been developed within the framework of this undergraduate thesis. This experimental research it’s associated with e-waste, where highlights insights into the recycling process of the battery mobile devices’s
