L-systems are string rewriting mechanisms used to create images of complex organisms from a simple set of an axiom and production rules. They have also been used to create music. This study developed a Musical Instrument Digital Interface interpretation suitable for applying to strings generated by L-systems that had been previously developed to model the growth of filamentous microbes (fungi and bacteria). The resulting sound files helped distinguish between organisms with different growth rates, provided some insight into the temporal differences among stages of growth, and also resulted in interesting musical pieces.
