Silvio-Alejandro López-Pazos has been a Professor in Microbiology at the Faculty of Sciences at the Universidad Antonio Nariño (Bogotá-Colombia). His work in several areas of biological sciences, and parts of this work forge links between agriculture and biotechnology, especially microbiology, plant pathology, recombinant DNA technology or intellectual property rights. He has many years of experience on many different aspects of the microbiology applications such as biological control of pest using extremophile microorganisms and recombinant DNA technology in biotechnological applications such as genetically modified crops, intellectual property rights, or growth promotion in plants. In these studies molecular and genomic tools and biological assays were applied for typing protein activities Some of his studies showed that microbiological toxins had activity against Tecia solanivora, Premnotrypes vorax, Asymmathetes vulcanorum (potato pests) and Hypothenemus hampei (coffee crops pest). More recently his research has concentrated on novel proteins from different biological sources for biotechnological approaches by means of analysis of microbiological genomes, and specifically he found proteins with possible activity against pests from Bacillus weihenstephanensis and Aquifex sp. He decided to make a sharp move to the field of plant biotechnology for crop improvement, where he spend time studying novel applications of biochemical compounds for crop protection and environmental management, genetically modified crops and biosafety, and agricultural patents. So, professor López-Pazos identified antimicrobial peptides from Chamaemelum nobile with potential in plant pathogen control, transgenic gene flow in Colombian corn, and genetically modified soybean patents. Currently he studies the field of extremophiles as a tool for understanding of the physico-chemical conditions defining the life, and on this way, Dr. López-Pazos try to give novel biotechnology options for agriculture, including growth promotion and stress adaptation in plants. Recently, he works in identification of factors such as siderophore production, phosphate solubilization or nitrogen fixation in extremophile microorganisms with potential in growth promotion in Phaseolus vulgaris.
