Manutenção de isolados fúngicos de importância em alimentos

Abstract

The collections of fungal cultures are an important biological patrimony, useful to mycology as a support in scientific work. They provide specimens at any time for identification, morphophysiological studies, life cycle, aiming to contribute to the study improvement of each specimen. There is no preservation method that is efficient and recommended for different groups of fungi, and it is more appropriate to maintain the original characteristics of the crop, ie, viability, sporulation and pathogenicity, avoiding undesired mutations and contamination. The choice will depend on the infrastructure of the laboratory, the micro-organism under study and the objectives of the work. The objective of this work was to evaluate the sporulation and viability of the fungal isolates used, thus confirming the efficiency of the silica gel preservation method. All isolates were maintained viable during the study period.
