Abstract
Eficiencia de la larva Plagiohammus maculosus bates en la biodegradación de polietileno de baja densidad, bajo condiciones de laboratorio, 2020.
El estudio tuvo como objetivo general evaluar la biodegradación del polietileno de baja densidad (PEBD) mediante la larva Plagiohammus maculosus bates bajo condiciones de laboratorio. La investigación fue de tipo aplicada, ya que buscó resolver un problema práctico, y de nivel explicativo, debido a su enfoque en probar hipótesis y explicar relaciones causales. Se utilizó un diseño experimental factorial con tres tratamientos y tres repeticiones. La población incluyó 0,0427 kg/hab/día de PEBD generados en Moyobamba, y la muestra fue de 540 gramos de PEBD. Se aplicaron técnica de observación y registro sistemático mediante fichas de datos como instrumento. El análisis estadístico se realizó con SPSS v.24 y ANOVA factorial, permitiendo comparar tratamientos. Los resultados principales mostraron que 10 gramos de larvas aplicadas a 30 °C durante 72 horas fueron más eficaces, alcanzando una eficiencia de biodegradación del 53.53%. Se determinó que el tiempo y la temperatura óptimos eran 72 horas y 30 °C, respectivamente. El análisis del microbiota endógeno de las larvas identificó bacterias gran negativas las cuales son clave en la biodegradación. En conclusión, la larva Plagiohammus maculosus bates demostró ser un agente biológico eficaz para degradar el PEBD en condiciones controladas. El estudio sugiere su potencial para tratamientos de residuos plásticos y resalta la importancia de investigaciones adicionales para optimizar el proceso y su posible aplicación a gran escala.
Efficiency of Plagiohammus maculosus Bates larvae in the biodegradation of low-density polyethylene under laboratory conditions, 2020. The study's main objective was to evaluate the biodegradation of low-density polyethylene (LDPE) using Plagiohammus maculosus Bates larvae under laboratory conditions. The research was applied, aiming to solve a practical problem, and explanatory, focusing on testing hypotheses and explaining causal relationships. A factorial experimental design with three treatments and three replications was used. The population included 0.0427 kg/inhabitant/day of LDPE generated in Moyobamba, with a sample size of 540 grams of LDPE. Systematic observation and recording techniques were applied using data sheets as instruments. Statistical analysis was performed using SPSS v.24 and factorial ANOVA, allowing treatment comparisons. The main results showed that 10 grams of larvae applied at 30 °C for 72 hours were most effective, achieving a biodegradation efficiency of 53.53%. The optimal time and temperature were determined to be 72 hours and 30 °C, respectively. The endogenous microbiota analysis of the larvae identified Gram-negative bacteria as key agents in the biodegradation process. In conclusion, Plagiohammus maculosus Bates larvae proved to be an effective biological agent for degrading LDPE under controlled conditions. The study suggests its potential for plastic waste treatment and highlights the importance of further research to optimize the process and explore its large-scale application.
