Zusammenfassung: | This work was carried out to evaluate the efficiency of the culture medium from sour guava (Psidium araca) against commercial media in the growth of three native strains: Candida guillermondii, Candida famata and Candida sp. Microbial growth was evaluated at different concentrations of fruit, 5, 10, 25, 50% w /v, using as control the commercial media: Malta, Sabouraud and PDA (Potato Dextrose Agar). The productivity and selectivity of the sour guava medium was determined by the Ecometric method in a time of 48 hours. The applied statistical analysis to evaluate and compare growth of strains in commercial culture medium and in the medium from sour guava at different concentrations showed: Candida guillermondii grew greater than or equal to 25 and 50% w / v compared with commercial medium, Candida famata and Candida sp showed better growth at 5% w / v, with respect to commercial medium. The results showed that the medium is highly productive and non-selective representing an alternative to the conservation, maintenance and development of the yeasts. |
