Abstract
In the search for natural substances, with antifungical activity of anamorphic fungus species was carried out a cultural characterization of tow strains (2432 and 3528), belonging to the Beltrania and Beltraniella genus located in the INIFAT micoteca. The aim of this paper was to optimize the production of bioactive substances. During the experiments six different mediums are studied (OA, PDA, MA, CA, Rice and CMA), below equaling conditions of temperature and humidity, being carried out daily mensurations of the growth of the colonies. For the cultural characterization the following parameters were sized: color, forms, surface, borders and height. To the 13 days also It determines the conidiums presence for observation to the optic microscope. The results showed a better morphologic development in the Potato medium for both strains. The means of Rice was the less one favorable for the growth and development of the tow strains. As soon as the conidiums production, the 2432 strain alone it showed a slight presence of these in the Oat means, while the 3528 strain produced abundant in this same medium and acceptable in the Corn and Potato mediums. These results constitute a contribution to the studies guided to the obtaining of bioproducts of microbial origin for their use in the agroecology handling of plagues.
