Penitentiaries: Bringing microbiological literacy to the fringes of society

Abstract

This report highlights a science outreach effort for prisons launched by the Spanish National Research Council (CSIC) in collaboration with the NGO Solidarios para el Desarrollo. The Microbiology-focused part of the initiative aims at educating inmates on some basic facts, in order to raise awareness about microorganisms and their impact on daily life. The outline of the talks, inspired by the International Initiative for Microbial Literacy, aims to encourage this collective to move from passive listeners into active participants, helping them understand that Earth is a microbial planet, and that their bodies harbour vast microbiomes that affect their health and social interactions. The talks introduce Microbiology using simple metaphors and emphasize the role of beneficial microorganisms. By explaining the power of microscopes, inmates are shown the hidden microbial world that surrounds them, sparking interest and curiosity. The talks also cover microbial biotechnology, using examples such as bioplastics, anti-cavity bacteria, and skin microorganisms designed for acne prevention. Overall, this outreach initiative seeks to provide inmates with valuable scientific knowledge, fostering curiosity and critical thinking. Despite the challenges of delivering such content in a prison setting, the initiative demonstrates that even marginalized groups can benefit from microbiological literacy, helping them to both endure their terms and eventually reintegrate into society.
