CURIA, María V; D'ALESSANDRO, Oriana  e  BRIAND, Laura E. A Simple and Low Cost Experiment as a Tool to Teach Concepts in Biotechnology. Form. Univ. [online]. 2010, vol.3, n.1, pp.27-30. ISSN 0718-5006.  http://dx.doi.org/10.4067/S0718-50062010000100005.

A simple experiment that can be applied to the teaching of biotechnology to students of either elementary, high school or university level is proposed. The experiment consists of the fermentation of sugarwith commercial yeast. This process produces carbón dioxide that is collected in a balloon as a visual indicator of the progress of the fermentation reaction. This particular experiment is a good method to teach various concepts related with chemistry, physics, biology and biotechnology. The applications of the proposed fermentation experiment using microorganisms represents a direct connection for the students to understand common and domestic processes such as dough rising or production of alcoholic beverages.

Palavras-chave : biotechnology; fermentation; yeasts; natural science; teaching.
