Construção de bacterioteca em instituição de ensino superior para fins didáticos e de pesquisa

Abstract: Introdução: As bacteriotecas possuem um para grande relevância para Instituições de Ensino Superior, tanto para uso didático, quanto para uso em pesquisas. Os métodos de estocagem visam preservar os aspectos morfofisiológicos dos espécimes para sua utilização a qualquer momento. As técnicas de para conservação microbiana podem ser a curto prazo, médio prazo e longo prazo. Dentre os princípios de cada técnica, os métodos de criopreservação com congelamentos comum e ultracongelamento associados a aditivos criopr… Show more

“…All tests were repeated in 10 tubes and frozen at -20 and -80°C, followed by the viability test after one day of freezing to evaluate frozen strains' activity metabolism. The concentrations of the cryoprotectants were chosen based on the studies by Amorim and colleagues [4] and Becheleni and colleagues [7] with the necessary additions and alterations.…”

“…However, medium (-20ºC) and long-term freezing methods, if not carried out effectively according to the needs of each microorganism, can cause a deleterious effect, mainly on the cell membrane, and eventually cause cell death, because of the formation of crystals inside the cell. Therefore, it is essential to add cryoprotectants whose action protects against damage caused by freezing [4].…”
