| Para el control de la antracnosis del frijol (Phaseolus vulgaris L.) en invernadero y campo, se evaluó el efecto del extracto crudo (EC) y la mezcla de compuestos bioactivos afinina (A) y decatrién bornilo (DB), obtenidos de la raíz de Heliopsis longipes 'A. Gray' Blake. También se evaluó el efecto sobre la colonización de la raíz del frijol por hongos micorrízicos vesículo arbusculares (HMVA) y la nodulación de bacterias fijadoras de nitrógeno. En invernadero, dos de las concentraciones del EC (700/70 y 70/7 µg mL-1) y A/DB (700/70 y 70/7 µg mL-1), redujeron la incidencia de la antracnosis en 90%, sin reducción significativa (p>0.05) del peso seco de las plantas tratadas. En campo, las concentraciones evaluadas de EC (70/7 µg mL-1) y A/DB (70/7 µg... |

| Abstract Stress tolerance is a key attribute that must be considered when using yeast cells for industrial applications. High temperature is one factor that can cause stress in yeast. High environmental temperature in particular may exert a natural selection pressure to evolve yeasts into thermotolerant strains. In the present study, three yeasts (Saccharomyces cerevisiae, MC4, and Kluyveromyces marxianus, OFF1 and SLP1) isolated from hot environments were exposed to increased temperatures and were then compared with a laboratory yeast strain. Their resistance to high temperature, oxidative stress, and antioxidant response were evaluated, along with the fatty acid composition of their cell membranes. The SLP1 strain showed a higher specific growth rate,... |
