Abstract Light quality is a crucial abiotic environmental factor that influences the growth and β-carotene accumulation on Dunaliella salina. However, influence of primary photochemical reactions D. salina physiological mechanisms regulating metabolism remains unclear at present. This study involved batch culture using low light (40 ± 5 μmol photons m-2 s-1, without inhibiting photosynthetic electron transfer) provided by different colored LEDs. Our results indicated rate, chlorophyll a/chlorophyll b/β-carotene content cells were higher under BL RL than WL GL. The absorption rates chloroplasts in algae (22.8% 18.6%, respectively) those GL (14.0% 10.2%, respectively), which was attributed to reduced energy dissipation increased efficiency RL. enhanced synthesis capability cells.

La crisis provocada por la pandemia COVID-19 condujo a las universidades reestructurar rápidamente sus programas de estudios. El área experimental ciencias biológicas se vio afectada ya que los laboratorios presenciales son parte integral educación superior. Este hecho, llevó materia biotecnología adopte su programa estudios virtuales y modelamientos in silico. De esta manera el objetivo este trabajo es mejorar formación académica en tiempos críticos, utilizando silico como un mecanismo enseñanza-aprendizaje contexto con estudiantes biotecnología. Para simular procesos biotecnológicos Dunaliella salina tomó modelo gen psy, amplificación del PCR, resguardo gen, caracterización enzima biosíntesis carotenoides. Las aptitudes conocimientos adquiridos fueron evaluados través una encuesta 156 cursaron biotecnología-UPSE. Los demostraron psy comparte alta similitud cobertura superior 81% otras especies vegetales, resultó producto 1218 pb. Mientras estructura proteica alcanzó 0,69 QMING activación cascada señalización celular demostró 5 genes involucrados Finalmente, percepción positiva favor 70,83%. aplicación permitieron biológicos experimentales comprender efectiva no presencialidad.
