Estirpes standard bacterial strains, ways of obtaining donation and maintenance in teaching and research

Abstract

Good Laboratory Practices (GLP) refer to the quality system that contributes to guarantee the quality of research results,
including the use of standard strains to control the performance of culture media, dyes, and reactions. Standard strains or reference bacteria are cultures originated from a collection of cultures nationally and/or internationally recognized, followed by a certificate describing their phenotypic and genotypic characteristics and other relevant information. The preservation of their original characteristics is one of the essential requirements for their viability, important for their reproduction in industrial processes and in pure and applied research experiments. The objective of this work was to compile and disseminate information on the ways of obtaining donation of standard strains to teaching and research laboratories and their maintenance in microbiological analysis laboratories. Through a bibliographic survey, information was compiled on institutions that donate reference material and on methods of standard strain reactivation and adequate maintenance. The availability of this material through donations and adequate maintenance according to laboratory conditions allow fulfilling GLP requirements and the quality of the works developed.
