| Abstract (English): | Introduction. The excessive consumption of plastics generates environmental contamination, which is a growing problem and generates intergenerational impacts. Objective. The purpose of this research was to evaluate the biodegradative potential of bacteria and fungi on plastic, isolated from plastic wrappings damaged by time from garbage collection sites in the municipality of Valledupar. Methodology. The research approach is quantitative. The research design is observational, analytical, prospective and transversal. Samples were taken from plastic bags deteriorated by time, at a depth of 20 cm, were sown for pre-enrichment in a medium of mineral salts for 45 days, at three temperatures 30.5°C, 35.1°C and 27.3°C, then enriched in a medium of inorganic compounds at pH 5, pH 7 and pH 8 in triplicate. Results. Plastic biodegradation was observed in 41.2 % of the microbial consortium cultures, followed equally (29.4 %) in both bacteria and fungi. The bacteria identified as potential biodegraders were Serratia liquefaciens group, Serratia marcescens and Klebsiella aerogenes and the fungi Trichosporon mucoides and Candida ciferrii. Conclusions. It was possible to identify bacteria of the genus Serratia and Klebsiella and fungi of the genus Trichosporon and Candida, with the capacity to biodegrade plastics. This work allows for subsequent bioprospective studies and metabolic determination of the isolated microorganisms. [ABSTRACT FROM AUTHOR] |
| Abstract (Spanish): | Introducción. El consumo desmedido de plásticos genera una contaminación ambiental, constituyéndose en un problema que va en aumento y genera impactos intergeneracionales. Objetivo. El propósito de esta investigación fue evaluar el potencial biodegradador de las bacterias y hongos sobre el plástico, aisladas de envolturas dañadas por el tiempo a partir de los lugares de recopilación de basuras del municipio de Valledupar (Colombia). Metodología. El enfoque de la investigación es cuantitativo. El diseño de investigación observacional, analítico, prospectivo y transversal. Se tomaron muestras de bolsas plásticas deterioradas por el tiempo, a una profundidad de 20 cm, se sembraron para preenriquecerlas en un medio de sales minerales por 45 días, en 3 temperaturas 30.5°C, 35.1°C y 27.3°C, luego se enriquecieron en un medio de compuestos inorgánicos a un pH 5, pH 7 y pH 8 por triplicado. Resultados. Se observó que hubo biodegradación de plástico, en el 41,2 % de los cultivos de consorcio microbiano, seguido por igual (29.4 %) tanto en bacterias como en hongos. Las bacterias identificadas como potenciales biodegradadoras, son Serratia liquefaciens group, Serratia marcescens y Klebsiella aerogenes y los hongos Trichosporon mucoides y Candida ciferrii. Conclusiones. Se logró identificar bacterias del género Serratia y Klebsiella y de hongos del género Trichosporon y Candida, con capacidad de biodegradación de plásticos. Este trabajo permite la facilidad de posteriores estudios de tipo bioprospectivo y determinación metabólica de los microorganismos aislados. [ABSTRACT FROM AUTHOR] |
